Version 1.6.2 - September 2, 2011
|
|
|
|
|
|
|
|
- Add --failover-only option to not leak work to backup pools when the primary
|
|
|
|
pool is lagging.
|
|
|
|
- Change recommendation to intensity 9 for dedicated miners.
|
|
|
|
- Fix the bouncing short term value by allowing it to change dynamically when
|
|
|
|
the latest value is very different from the rolling value, but damp the change
|
|
|
|
when it gets close.
|
|
|
|
- Use the curses_lock to protect the curses_active variable and test it under
|
|
|
|
lock.
|
|
|
|
- Go back to requesting work 2/3 of the way through the current scantime with
|
|
|
|
CPU mining as reports of mining threads running out of work have occurred with
|
|
|
|
only 5 seconds to retrieve work.
|
|
|
|
- Add start and stop time scheduling for regular time of day running or once off
|
|
|
|
start/stop options.
|
|
|
|
- Print summary on quit modes.
|
|
|
|
- Put some sanity checks on the times that can be input.
|
|
|
|
- Give a verbose message when no active pools are found and pause before
|
|
|
|
exiting.
|
|
|
|
- Add verbose message when a GPU fails to initialise, and disable the correct
|
|
|
|
GPU.
|
|
|
|
- Cryptopp asm32 was not correctly updated to the incremental nonce code so the
|
|
|
|
hash counter was bogus.
|
|
|
|
- Get rid of poorly executed curl check.
|
|
|
|
- If curl does not have sockopts, do not try to compile the
|
|
|
|
json_rpc_call_sockopt_cb function, making it possible to build against older
|
|
|
|
curl libraries.
|
|
|
|
- Most people expect /usr/local when an unspecified prefix is used so change to
|
|
|
|
that.
|
|
|
|
- Rename localgen occasions to getwork fail occasions since localgen is
|
|
|
|
unrelated now.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.6.1 - August 29, 2011
|
|
|
|
|
|
|
|
- Copy cgminer path, not cat it.
|
|
|
|
- Switching between redrawing windows does not fix the crash with old
|
|
|
|
libncurses, so redraw both windows, but only when the window size hasn't
|
|
|
|
changed.
|
|
|
|
- Reinstate minimum 1 extra in queue to make it extremely unlikely to ever have
|
|
|
|
0 staged work items and any idle time.
|
|
|
|
- Return -1 if no input is detected from the menu to prevent it being
|
|
|
|
interpreted as a 0.
|
|
|
|
- Make pthread, libcurl and libcurses library checks mandatory or fail.
|
|
|
|
- Add a --disable-opencl configure option to make it possible to override
|
|
|
|
detection of opencl and build without GPU mining support.
|
|
|
|
- Confusion over the variable name for number of devices was passing a bogus
|
|
|
|
value which likely was causing the zero sized binary issue.
|
|
|
|
- cgminer no longer supports default url user and pass so remove them.
|
|
|
|
- Don't show value of intensity since it's dynamic by default.
|
|
|
|
- Add options to explicitly enable CPU mining or disable GPU mining.
|
|
|
|
- Convert the opt queue into a minimum number of work items to have queued
|
|
|
|
instead of an extra number to decrease risk of getting idle devices without
|
|
|
|
increasing risk of higher rejects.
|
|
|
|
- Statify tv_sort.
|
|
|
|
- Check for SSE2 before trying to build 32 bit SSE2 assembly version. Prevents
|
|
|
|
build failure when yasm is installed but -msse2 is not specified.
|
|
|
|
- Add some defines to configure.ac to enable exporting of values and packaging,
|
|
|
|
and clean up output.
|
|
|
|
- Give convenient summary at end of ./configure.
|
|
|
|
- Display version information and add --version command line option, and make
|
|
|
|
sure we flush stdout.
|
|
|
|
- Enable curses after the mining threads are set up so that failure messages
|
|
|
|
won't be lost in the curses interface.
|
|
|
|
- Disable curses after inputting a pool if we requested no curses interface.
|
|
|
|
- Add an option to break out after successfully mining a number of accepted
|
|
|
|
shares.
|
|
|
|
- Exit with a failed return code if we did not reach opt_shares.
|
|
|
|
- The cpu mining work data can get modified before we copy it if we submit it
|
|
|
|
async, and the sync submission is not truly sync anyway, so just submit it sync.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.6.0 - August 26, 2011
|
|
|
|
|
|
|
|
- Make restarting of GPUs optional for systems that hang on any attempt to
|
|
|
|
restart them. Fix DEAD status by comparing it to last live time rather than
|
|
|
|
last attempted restart time since that happens every minute.
|
|
|
|
- Move staged threads to hashes so we can sort them by time.
|
|
|
|
- Create a hash list of all the blocks created and search them to detect when a
|
|
|
|
new block has definitely appeared, using that information to detect stale work
|
|
|
|
and discard it.
|
|
|
|
- Update configure.ac for newer autoconf tools.
|
|
|
|
- Use the new hashes directly for counts instead of the fragile counters
|
|
|
|
currently in use.
|
|
|
|
- Update to latest sse2 code from cpuminer-ng.
|
|
|
|
- Allow LP to reset block detect and block detect lp flags to know who really
|
|
|
|
came first.
|
|
|
|
- Get start times just before mining begins to not have very slow rise in
|
|
|
|
average.
|
|
|
|
- Add message about needing one server.
|
|
|
|
- We can queue all the necessary work without hitting frequent stales now with
|
|
|
|
the time and string stale protection active all the time. This prevents a
|
|
|
|
pool being falsely labelled as not providing work fast enough.
|
|
|
|
- Include uthash.h in distro.
|
|
|
|
- Implement SSE2 32 bit assembly algorithm as well.
|
|
|
|
- Fail gracefully if unable to open the opencl files.
|
|
|
|
- Make cgminer look in the install directory for the .cl files making make
|
|
|
|
install work correctly.
|
|
|
|
- Allow a custom kernel path to be entered on the command line.
|
|
|
|
- Bump threshhold for lag up to maximum queued but no staged work.
|
|
|
|
- Remove fragile source patching for bitalign, vectors et. al and simply pass it
|
|
|
|
with the compiler options.
|
|
|
|
- Actually check the value returned for the x-roll-ntime extension to make sure
|
|
|
|
it isn't saying N.
|
|
|
|
- Prevent segfault on exit for when accessory threads don't exist.
|
|
|
|
- Disable curl debugging with opt protocol since it spews to stderr.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.5.8 - August 23, 2011
|
|
|
|
|
|
|
|
- Minimise how much more work can be given in cpu mining threads each interval.
|
|
|
|
- Make the fail-pause progressively longer each time it fails until the network
|
|
|
|
recovers.
|
|
|
|
- Only display the lagging message if we've requested the work earlier.
|
|
|
|
- Clean up the pool switching to not be dependent on whether the work can roll
|
|
|
|
or not by setting a lagging flag and then the idle flag.
|
|
|
|
- Only use one thread to determine if a GPU is sick or well, and make sure to
|
|
|
|
reset the sick restart attempt time.
|
|
|
|
- The worksize was unintentionally changed back to 4k by mistake, this caused a
|
|
|
|
slowdown.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.5.7 - August 22, 2011
|
|
|
|
|
|
|
|
- Fix a crash with --algo auto
|
|
|
|
- Test at appropriate target difficulty now.
|
|
|
|
- Add per-device statics log output with --per-device-stats
|
|
|
|
- Fix breakage that occurs when 1 or 4 vectors are chosen on new phatk.
|
|
|
|
- Make rolltime report debug level only now since we check it every work
|
|
|
|
item.
|
|
|
|
- Add the ability to enable/disable per-device stats on the fly and match
|
|
|
|
logging on/off.
|
|
|
|
- Explicitly tell the compiler to retain the program to minimise the chance of
|
|
|
|
the zero sized binary errors.
|
|
|
|
- Add one more instruction to avoid one branch point in the common path in the
|
|
|
|
cl return code. Although this adds more ALUs overall and more branch points, the
|
|
|
|
common path code has the same number of ALUs and one less jmp, jmps being more
|
|
|
|
expensive.
|
|
|
|
- Explicitly link in ws2_32 on the windows build and update README file on how
|
|
|
|
to compile successfully on windows.
|
|
|
|
- Release cl resources should the gpu mining thread abort.
|
|
|
|
- Attempt to restart a GPU once every minute while it's sick.
|
|
|
|
- Don't kill off the reinit thread if it fails to init a GPU but returns safely.
|
|
|
|
- Only declare a GPU dead if there's been no sign of activity from the reinit
|
|
|
|
thread for 10 mins.
|
|
|
|
- Never automatically disable any pools but just specify them as idle if they're
|
|
|
|
unresponsive at startup.
|
|
|
|
- Use any longpoll available, and don't disable it if switching to a server that
|
|
|
|
doesn't have it. This allows you to mine solo, yet use the longpoll from a pool
|
|
|
|
even if the pool is the backup server.
|
|
|
|
- Display which longpoll failed and don't free the ram for lp_url since it
|
|
|
|
belongs to the pool hdr path.
|
|
|
|
- Make the tcp setsockopts unique to linux in the hope it allows freebsd et. al
|
|
|
|
to compile.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.5.6 - August 17, 2011
|
|
|
|
|
|
|
|
- New phatk and poclbm kernels. Updated phatk to be in sync with latest 2.2
|
|
|
|
courtesy of phateus. Custom modified to work best with cgminer.
|
|
|
|
- Updated output buffer code to use a smaller buffer with the kernels.
|
|
|
|
- Clean up the longpoll management to ensure the right paths go to the right
|
|
|
|
pool and display whether we're connected to LP or not in the status line.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.5.5 - August 16, 2011
|
|
|
|
|
|
|
|
- Rework entirely the GPU restart code. Strike a balance between code that
|
|
|
|
re-initialises the GPU entirely so that soft hangs in the code are properly
|
|
|
|
managed, but if a GPU is completely hung, the thread restart code fails
|
|
|
|
gracefully, so that it does not take out any other code or devices. This will
|
|
|
|
allow cgminer to keep restarting GPUs that can be restarted, but continue
|
|
|
|
mining even if one or more GPUs hangs which would normally require a reboot.
|
|
|
|
- Add --submit-stale option which submits all shares, regardless of whether they
|
|
|
|
would normally be considered stale.
|
|
|
|
- Keep options in alphabetical order.
|
|
|
|
- Probe for slightly longer for when network conditions are lagging.
|
|
|
|
- Only display the CPU algo when we're CPU mining.
|
|
|
|
- As we have keepalives now, blaming network flakiness on timeouts appears to
|
|
|
|
have been wrong. Set a timeout for longpoll to 1 hour, and most other
|
|
|
|
network connectivity to 1 minute.
|
|
|
|
- Simplify output code and remove HW errors from CPU stats.
|
|
|
|
- Simplify code and tidy output.
|
|
|
|
- Only show cpu algo in summary if cpu mining.
|
|
|
|
- Log summary at the end as per any other output.
|
|
|
|
- Flush output.
|
|
|
|
- Add a linux-usb-cgminer guide courtesy of Kano.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.5.4 - August 14, 2011
|
|
|
|
|
|
|
|
- Add new option: --monitor <cmd> Option lets user specify a command <cmd> that
|
|
|
|
will get forked by cgminer on startup. cgminer's stderr output subsequently gets
|
|
|
|
piped directly to this command.
|
|
|
|
- Allocate work from one function to be able to initialise variables added
|
|
|
|
later.
|
|
|
|
- Add missing fflush(stdout) for --ndevs and conclusion summary.
|
|
|
|
- Preinitialise the devices only once on startup.
|
|
|
|
- Move the non cl_ variables into the cgpu info struct to allow creating a new
|
|
|
|
cl state on reinit, preserving known GPU variables.
|
|
|
|
- Create a new context from scratch in initCQ in case something was corrupted to
|
|
|
|
maximise our chance of succesfully creating a new worker thread. Hopefully this
|
|
|
|
makes thread restart on GPU failure more reliable, without hanging everything
|
|
|
|
in the case of a completely wedged GPU.
|
|
|
|
- Display last initialised time in gpu management info, to know if a GPU has
|
|
|
|
been re-initialised.
|
|
|
|
- When pinging a sick cpu, flush finish and then ping it in a separate thread in
|
|
|
|
the hope it recovers without needing a restart, but without blocking code
|
|
|
|
elsewhere.
|
|
|
|
- Only consider a pool lagging if we actually need the work and we have none
|
|
|
|
staged despite queue requests stacking up. This decreases significantly the
|
|
|
|
amount of work that leaks to the backup pools.
|
|
|
|
- The can_roll function fails inappropriately in stale_work.
|
|
|
|
- Only put the message that a pool is down if not pinging it every minute. This
|
|
|
|
prevents cgminer from saying pool down at 1 minute intervals unless in debug
|
|
|
|
mode.
|
|
|
|
- Free all work in one place allowing us to perform actions on it in the future.
|
|
|
|
- Remove the extra shift in the output code which was of dubious benefit. In
|
|
|
|
fact in cgminer's implementation, removing this caused a miniscule speedup.
|
|
|
|
- Test each work item to see if it can be rolled instead of per-pool and roll
|
|
|
|
whenever possible, adhering to the 60 second timeout. This makes the period
|
|
|
|
after a longpoll have smaller dips in throughput, as well as requiring less
|
|
|
|
getworks overall thus increasing efficiency.
|
|
|
|
- Stick to rolling only work from the current pool unless we're in load balance
|
|
|
|
mode or lagging to avoid aggressive rolling imitating load balancing.
|
|
|
|
- If a work item has had any mining done on it, don't consider it discarded
|
|
|
|
work.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.5.3 - July 30, 2011
|
|
|
|
|
|
|
|
- Significant work went into attempting to make the thread restart code robust
|
|
|
|
to identify sick threads, tag them SICK after 1 minute, then DEAD after 5
|
|
|
|
minutes of inactivity and try to restart them. Instead of re-initialising the
|
|
|
|
GPU completely, only a new cl context is created to avoid hanging the rest of
|
|
|
|
the GPUs should the dead GPU be hung irrevocably.
|
|
|
|
- Use correct application name in syslog.
|
|
|
|
- Get rid of extra line feeds.
|
|
|
|
- Use pkg-config to check for libcurl version
|
|
|
|
- Implement per-thread getwork count with proper accounting to not over-account
|
|
|
|
queued items when local work replaces it.
|
|
|
|
- Create a command queue from the program created from source which allows us
|
|
|
|
to flush the command queue in the hope it will not generate a zero sized binary
|
|
|
|
any more.
|
|
|
|
- Be more willing to get work from the backup pools if the work is simply being
|
|
|
|
queued faster than it is being retrieved.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.5.2 - July 28, 2011
|
|
|
|
|
|
|
|
- Restarting a hung GPU can hang the rest of the GPUs so just declare it dead
|
|
|
|
and provide the information in the status.
|
|
|
|
- The work length in the miner thread gets smaller but doesn't get bigger if
|
|
|
|
it's under 1 second. This could end up leading to CPU under-utilisation and
|
|
|
|
lower and lower hash rates. Fix it by increasing work length if it drops
|
|
|
|
under 1 second.
|
|
|
|
- Make the "quiet" mode still update the status and display errors, and add a
|
|
|
|
new --real-quiet option which disables all output and can be set once while
|
|
|
|
running.
|
|
|
|
- Update utility and efficiency figures when displaying them.
|
|
|
|
- Some Intel HD graphics support the opencl commands but return errors since
|
|
|
|
they don't support opencl. Don't fail with them, just provide a warning and
|
|
|
|
disable GPU mining.
|
|
|
|
- Add http:// if it's not explicitly set for URL entries.
|
|
|
|
- Log to the output file at any time with warnings and errors, instead of just
|
|
|
|
when verbose mode is on.
|
|
|
|
- Display the correct current hash as per blockexplorer, truncated to 16
|
|
|
|
characters, with just the time.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.5.1 - July 27, 2011
|
|
|
|
|
|
|
|
- Two redraws in a row cause a crash in old libncurses so just do one redraw
|
|
|
|
using the main window.
|
|
|
|
- Don't adjust hash_div only up for GPUs. Disable hash_div adjustment for GPUs.
|
|
|
|
- Only free the thread structures if the thread still exists.
|
|
|
|
- Update both windows separately, but not at the same time to prevent the double
|
|
|
|
refresh crash that old libncurses has. Do the window resize check only when
|
|
|
|
about to redraw the log window to minimise ncurses cpu usage.
|
|
|
|
- Abstract out the decay time function and use it to make hash_div a rolling
|
|
|
|
average so it doesn't change too abruptly and divide work in chunks large enough
|
|
|
|
to guarantee they won't overlap.
|
|
|
|
- Sanity check to prove locking.
|
|
|
|
- Don't take more than one lock at a time.
|
|
|
|
- Make threads report out when they're queueing a request and report if they've
|
|
|
|
failed.
|
|
|
|
- Make cpu mining work submission asynchronous as well.
|
|
|
|
- Properly detect stale work based on time from staging and discard instead of
|
|
|
|
handing on, but be more lax about how long work can be divided for up to the
|
|
|
|
scantime.
|
|
|
|
- Do away with queueing work separately at the start and let each thread grab
|
|
|
|
its own work as soon as it's ready.
|
|
|
|
- Don't put an extra work item in the queue as each new device thread will do so
|
|
|
|
itself.
|
|
|
|
- Make sure to decrease queued count if we discard the work.
|
|
|
|
- Attribute split work as local work generation.
|
|
|
|
- If work has been cloned it is already at the head of the list and when being
|
|
|
|
reinserted into the queue it should be placed back at the head of the list.
|
|
|
|
- Dividing work is like the work is never removed at all so treat it as such.
|
|
|
|
However the queued bool needs to be reset to ensure we *can* request more work
|
|
|
|
even if we didn't initially.
|
|
|
|
- Make the display options clearer.
|
|
|
|
- Add debugging output to tq_push calls.
|
|
|
|
- Add debugging output to all tq_pop calls.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.5.0 - July 26, 2011
|
|
|
|
|
|
|
|
- Increase efficiency of slow mining threads such as CPU miners dramatically. Do
|
|
|
|
this by detecting which threads cannot complete searching a work item within the
|
|
|
|
scantime and then divide up a work item into multiple smaller work items.
|
|
|
|
Detect the age of the work items and if they've been cloned before to prevent
|
|
|
|
doing the same work over. If the work is too old to be divided, then see if it
|
|
|
|
can be time rolled and do that to generate work. This dramatically decreases the
|
|
|
|
number of queued work items from a pool leading to higher overall efficiency
|
|
|
|
(but the same hashrate and share submission rate).
|
|
|
|
- Don't request work too early for CPUs as CPUs will scan for the full
|
|
|
|
opt_scantime anyway.
|
|
|
|
- Simplify gpu management enable/disable/restart code.
|
|
|
|
- Implement much more accurate rolling statistics per thread and per gpu and
|
|
|
|
improve accuracy of rolling displayed values.
|
|
|
|
- Make the rolling log-second average more accurate.
|
|
|
|
- Add a menu to manage GPUs on the fly allowing you to enable/disable GPUs or
|
|
|
|
try restarting them.
|
|
|
|
- Keep track of which GPUs are alive versus enabled.
|
|
|
|
- Start threads for devices that are even disabled, but don't allow them to
|
|
|
|
start working.
|
|
|
|
- The last pool is when we are low in total_pools, not active_pools.
|
|
|
|
- Make the thread restart do a pthread_join after disabling the device, only
|
|
|
|
re-enabling it if we succeed in restarting the thread. Do this from a separate
|
|
|
|
thread so as to not block any other code.This will allow cgminer to continue
|
|
|
|
even if one GPU hangs.
|
|
|
|
- Try to do every curses manipulation under the curses lock.
|
|
|
|
- Only use the sockoptfunction if the version of curl is recent enough.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.4.1 - July 24, 2011
|
|
|
|
|
|
|
|
- Do away with GET for dealing with longpoll forever. POST is the one that works
|
|
|
|
everywhere, not the other way around.
|
|
|
|
- Detect when the primary pool is lagging and start queueing requests on backup
|
|
|
|
pools if possible before needing to roll work.
|
|
|
|
- Load balancing puts more into the current pool if there are disabled pools.
|
|
|
|
Fix.
|
|
|
|
- Disable a GPU device should the thread fail to init.
|
|
|
|
- Out of order command queue may fail on osx. Try without if it fails.
|
|
|
|
- Fix possible dereference on blank inputs during input_pool.
|
|
|
|
- Defines missing would segfault on --help when no sse mining is built in.
|
|
|
|
- Revert "Free up resources/stale compilers." - didn't help.
|
|
|
|
- Only try to print the status of active devices or it would crash.
|
|
|
|
- Some hardware might benefit from the less OPS so there's no harm in leaving
|
|
|
|
kernel changes that do that apart from readability of the code.
|
|
|
|
|
|
|
|
Version 1.4.0 - July 23, 2011
|
|
|
|
|
|
|
|
- Feature upgrade: Add keyboard input during runtime to allow modification of
|
|
|
|
and viewing of numerous settings such as adding/removing pools, changing
|
|
|
|
multipool management strategy, switching pools, changing intensiy, verbosity,
|
|
|
|
etc. with a simple keypress menu system.
|
|
|
|
- Free up resources/stale compilers.
|
|
|
|
- Kernels are safely flushed in a way that allows out of order execution to
|
|
|
|
work.
|
|
|
|
- Sometimes the cl compiler generates zero sized binaries and only a reboot
|
|
|
|
seems to fix it.
|
|
|
|
- Don't try to stop/cancel threads that don't exist.
|
|
|
|
- Only set option to show devices and exit if built with opencl support.
|
|
|
|
- Enable curses earlier and exit with message in main for messages to not be
|
|
|
|
lost in curses windows.
|
|
|
|
- Make it possible to enter server credentials with curses input if none are
|
|
|
|
specified on the command line.
|
|
|
|
- Abstract out a curses input function and separate input pool function to allow
|
|
|
|
for live adding of pools later.
|
|
|
|
- Remove the nil arguments check to allow starting without parameters.
|
|
|
|
- Disable/enable echo & cbreak modes.
|
|
|
|
- Add a thread that takes keyboard input and allow for quit, silent, debug,
|
|
|
|
verbose, normal, rpc protocol debugging and clear screen options.
|
|
|
|
- Add pool option to input and display current pool status, pending code to
|
|
|
|
allow live changes.
|
|
|
|
- Add a bool for explicit enabling/disabling of pools.
|
|
|
|
- Make input pool capable of bringing up pools while running.
|
|
|
|
- Do one last check of the work before submitting it.
|
|
|
|
- Implement the ability to live add, enable, disable, and switch to pools.
|
|
|
|
- Only internally test for block changes when the work matches the current pool
|
|
|
|
to prevent interleaved block change timing on multipools.
|
|
|
|
- Display current pool management strategy to enable changing it on the fly.
|
|
|
|
- The longpoll blanking of the current_block data may not be happening before
|
|
|
|
the work is converted and appears to be a detected block change. Blank the
|
|
|
|
current block be
|
|
|
|
- Make --no-longpoll work again.
|
|
|
|
- Abstract out active pools count.
|
|
|
|
- Allow the pool strategy to be modified on the fly.
|
|
|
|
- Display pool information on the fly as well.
|
|
|
|
- Add a menu and separate out display options.
|
|
|
|
- Clean up the messy way the staging thread communicates with the longpoll
|
|
|
|
thread to determine who found the block first.
|
|
|
|
- Make the input windows update immediately instead of needing a refresh.
|
|
|
|
- Allow log interval to be set in the menu.
|
|
|
|
- Allow scan settings to be modified at runtime.
|
|
|
|
- Abstract out the longpoll start and explicitly restart it on pool change.
|
|
|
|
- Make it possible to enable/disable longpoll.
|
|
|
|
- Set priority correctly on multipools. Display priority and alive/dead
|
|
|
|
information in display_pools.
|
|
|
|
- Implement pool removal.
|
|
|
|
- Limit rolltime work generation to 10 iterations only.
|
|
|
|
- Decrease testing log to info level.
|
|
|
|
- Extra refresh not required.
|
|
|
|
- With huge variation in GPU performance, allow intensity to go from -10 to +10.
|
|
|
|
- Tell getwork how much of a work item we're likely to complete for future
|
|
|
|
splitting up of work.
|
|
|
|
- Remove the mandatory work requirement at startup by testing for invalid work
|
|
|
|
being passed which allows for work to be queued immediately. This also
|
|
|
|
removes the requirem
|
|
|
|
- Make sure intensity is carried over to thread count and is at least the
|
|
|
|
minimum necessary to work.
|
|
|
|
- Unlocking error on retry. Locking unnecessary anyway so remove it.
|
|
|
|
- Clear log window from consistent place. No need for locking since logging is
|
|
|
|
disabled during input.
|
|
|
|
- Cannot print the status of threads that don't exist so just queue enough work
|
|
|
|
for the number of mining threads to prevent crash with -Q N.
|
|
|
|
- Update phatk kernel to one with new parameters for slightly less overhead
|
|
|
|
again. Make the queue kernel parameters call a function pointer to select
|
|
|
|
phatk or poclbm.
|
|
|
|
- Make it possible to select the choice of kernel on the command line.
|
|
|
|
- Simplify the output part of the kernel. There's no demonstrable advantage from
|
|
|
|
more complexity.
|
|
|
|
- Merge pull request #18 from ycros/cgminer
|
|
|
|
- No need to make leaveok changes win32 only.
|
|
|
|
- Build support in for all SSE if possible and only set the default according to
|
|
|
|
machine capabilities.
|
|
|
|
- Win32 threading and longpoll keepalive fixes.
|
|
|
|
- Win32: Fix for mangled output on the terminal on exit.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.3.1 - July 20, 2011
|
|
|
|
|
|
|
|
- Feature upgrade; Multiple strategies for failover. Choose from default which
|
|
|
|
now falls back to a priority order from 1st to last, round robin which only
|
|
|
|
changes pools when one is idle, rotate which changes pools at user-defined
|
|
|
|
intervals, and load-balance which spreads the work evenly amongst all pools.
|
|
|
|
- Implement pool rotation strategy.
|
|
|
|
- Implement load balancing algorithm by rotating requests to each pool.
|
|
|
|
- Timeout on failed discarding of staged requests.
|
|
|
|
- Implement proper flagging of idle pools, test them with the watchdog thread,
|
|
|
|
and failover correctly.
|
|
|
|
- Move pool active test to own function.
|
|
|
|
- Allow multiple strategies to be set for multipool management.
|
|
|
|
- Track pool number.
|
|
|
|
- Don't waste the work items queued on testing the pools at startup.
|
|
|
|
- Reinstate the mining thread watchdog restart.
|
|
|
|
- Add a getpoll bool into the thread information and don't restart threads stuck
|
|
|
|
waiting on work.
|
|
|
|
- Rename the idlenet bool for the pool for later use.
|
|
|
|
- Allow the user/pass userpass urls to be input in any order.
|
|
|
|
- When json rpc errors occur they occur in spits and starts, so trying to limit
|
|
|
|
them with the comms error bool doesn't stop a flood of them appearing.
|
|
|
|
- Reset the queued count to allow more work to be queued for the new pool on
|
|
|
|
pool switch.
|
|
|
|
|
|
|
|
Version 1.3.0 - July 19, 2011
|
|
|
|
|
|
|
|
- Massive infrastructure update to support pool failover.
|
|
|
|
- Accept multiple parameters for url, user and pass and set up structures of
|
|
|
|
pool data accordingly.
|
|
|
|
- Probe each pool for what it supports.
|
|
|
|
- Implement per pool feature support according to rolltime support as
|
|
|
|
advertised by server.
|
|
|
|
- Do switching automatically based on a 300 second timeout of locally generated
|
|
|
|
work or 60 seconds of no response from a server that doesn't support rolltime.
|
|
|
|
- Implement longpoll server switching.
|
|
|
|
- Keep per-pool data and display accordingly.
|
|
|
|
- Make sure cgminer knows how long the pool has actually been out for before
|
|
|
|
deeming it a prolonged outage.
|
|
|
|
- Fix bug with ever increasing staged work in 1.2.8 that eventually caused
|
|
|
|
infinite rejects.
|
|
|
|
- Make warning about empty http requests not show by default since many
|
|
|
|
servers do this regularly.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.2.8 - July 18, 2011
|
|
|
|
|
|
|
|
- More OSX build fixes.
|
|
|
|
- Add an sse4 algorithm to CPU mining.
|
|
|
|
- Fix CPU mining with other algorithms not working.
|
|
|
|
- Rename the poclbm file to ensure a new binary is built since.
|
|
|
|
- We now are guaranteed to have one fresh work item after a block change and we
|
|
|
|
should only discard staged requests.
|
|
|
|
- Don't waste the work we retrieve from a longpoll.
|
|
|
|
- Provide a control lock around global bools to avoid racing on them.
|
|
|
|
- Iterating over 1026 nonces when confirming data from the GPU is old code
|
|
|
|
and unnecessary and can lead to repeats/stales.
|
|
|
|
- The poclbm kernel needs to be updated to work with the change to 4k sized
|
|
|
|
output buffers.
|
|
|
|
- longpoll seems to work either way with post or get but some servers prefer
|
|
|
|
get so change to httpget.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.2.7 - July 16, 2011
|
|
|
|
|
|
|
|
- Show last 8 characters of share submitted in log.
|
|
|
|
- Display URL connected to and user logged in as in status.
|
|
|
|
- Display current block and when it was started in the status line.
|
|
|
|
- Only pthread_join the mining threads if they exist as determined by
|
|
|
|
pthread_cancel and don't fail on pthread_cancel.
|
|
|
|
- Create a unique work queue for all getworks instead of binding it to thread 0
|
|
|
|
to avoid any conflict over thread 0's queue.
|
|
|
|
- Clean up the code to make it clear it's watchdog thread being messaged to
|
|
|
|
restart the threads.
|
|
|
|
- Check the current block description hasn't been blanked pending the real
|
|
|
|
new current block data.
|
|
|
|
- Re-enable signal handlers once the signal has been received to make it
|
|
|
|
possible to kill cgminer if it fails to shut down.
|
|
|
|
- Disable restarting of CPU mining threads pending further investigation.
|
|
|
|
- Update longpoll messages.
|
|
|
|
- Add new block data to status line.
|
|
|
|
- Fix opencl tests for osx.
|
|
|
|
- Only do local generation of work if the work item is not stale itself.
|
|
|
|
- Check for stale work within the mining threads and grab new work if
|
|
|
|
positive.
|
|
|
|
- Test for idle network conditions and prevent threads from being restarted
|
|
|
|
by the watchdog thread under those circumstances.
|
|
|
|
- Make sure that local work generation does not continue indefinitely by
|
|
|
|
stopping it after 10 minutes.
|
|
|
|
- Tweak the kernel to have a shorter path using a 4k buffer and a mask on the
|
|
|
|
nonce value instead of a compare and loop for a shorter code path.
|
|
|
|
- Allow queue of zero and make that default again now that we can track how
|
|
|
|
work is being queued versus staged. This can decrease reject rates.
|
|
|
|
- Queue precisely the number of mining threads as longpoll_staged after a
|
|
|
|
new block to not generate local work.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.2.6 - July 15, 2011
|
|
|
|
|
|
|
|
- Put a current system status line beneath the total work status line
|
|
|
|
- Fix a counting error that would prevent cgminer from correctly detecting
|
|
|
|
situations where getwork was failing - this would cause stalls sometimes
|
|
|
|
unrecoverably.
|
|
|
|
- Limit the maximum number of requests that can be put into the queue which
|
|
|
|
otherwise could get arbitrarily long during a network outage.
|
|
|
|
- Only count getworks that are real queue requests.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.2.5 - July 15, 2011
|
|
|
|
|
|
|
|
- Conflicting -n options corrected
|
|
|
|
- Setting an intensity with -I disables dynamic intensity setting
|
|
|
|
- Removed option to manually disable dynamic intensity
|
|
|
|
- Improve display output
|
|
|
|
- Implement signal handler and attempt to clean up properly on exit
|
|
|
|
- Only restart threads that are not stuck waiting on mandatory getworks
|
|
|
|
- Compatibility changes courtesy of Ycros to build on mingw32 and osx
|
|
|
|
- Explicitly grab first work item to prevent false positive hardware errors
|
|
|
|
due to working on uninitialised work structs
|
|
|
|
- Add option for non curses --text-only output
|
|
|
|
- Ensure we connect at least once successfully before continuing to retry to
|
|
|
|
connect in case url/login parameters were wrong
|
|
|
|
- Print an executive summary when cgminer is terminated
|
|
|
|
- Make sure to refresh the status window
|
|
|
|
|
|
|
|

Version 1.0.2
|
|
|
|
|
|
|
|
- Linux x86_64 optimisations - Con Kolivas
|
|
|
|
- Optimise for x86_64 by default by using sse2_64 algo
|
|
|
|
- Detects CPUs and sets number of threads accordingly
|
|
|
|
- Uses CPU affinity for each thread where appropriate
|
|
|
|
- Sets scheduling policy to lowest possible
|
|
|
|
- Minor performance tweaks
|
|
|
|
|
|
|
|
Version 1.0.1 - May 14, 2011
|
|
|
|
|
|
|
|
- OSX support
|
|
|
|
|
|
|
|
Version 1.0 - May 9, 2011
|
|
|
|
|
|
|
|
- jansson 2.0 compatibility
|
|
|
|
- correct off-by-one in date (month) display output
|
|
|
|
- fix platform detection
|
|
|
|
- improve yasm configure bits
|
|
|
|
- support full URL, in X-Long-Polling header
|
|
|
|
|
|
|
|
Version 0.8.1 - March 22, 2011
|
|
|
|
|
|
|
|
- Make --user, --pass actually work
|
|
|
|
|
|
|
|
- Add User-Agent HTTP header to requests, so that server operators may
|
|
|
|
more easily identify the miner client.
|
|
|
|
|
|
|
|
- Fix minor bug in example JSON config file
|
|
|
|
|
|
|
|
Version 0.8 - March 21, 2011
|
|
|
|
|
|
|
|
- Support long polling: http://deepbit.net/longpolling.php
|
|
|
|
|
|
|
|
- Adjust max workload based on scantime (default 5 seconds,
|
|
|
|
or 60 seconds for longpoll)
|
|
|
|
|
|
|
|
- Standardize program output, and support syslog on Unix platforms
|
|
|
|
|
|
|
|
- Suport --user/--pass options (and "user" and "pass" in config file),
|
|
|
|
as an alternative to the current --userpass
|
|
|
|
|
|
|
|
Version 0.7.2 - March 14, 2011
|
|
|
|
|
|
|
|
- Add port of ufasoft's sse2 assembly implementation (Linux only)
|
|
|
|
This is a substantial speed improvement on Intel CPUs.
|
|
|
|
|
|
|
|
- Move all JSON-RPC I/O to separate thread. This reduces the
|
|
|
|
number of HTTP connections from one-per-thread to one, reducing resource
|
|
|
|
usage on upstream bitcoind / pool server.
|
|
|
|
|
|
|
|
Version 0.7.1 - March 2, 2011
|
|
|
|
|
|
|
|
- Add support for JSON-format configuration file. See example
|
|
|
|
file example-cfg.json. Any long argument on the command line
|
|
|
|
may be stored in the config file.
|
|
|
|
- Timestamp each solution found
|
|
|
|
- Improve sha256_4way performance. NOTE: This optimization makes
|
|
|
|
the 'hash' debug-print output for sha256_way incorrect.
|
|
|
|
- Use __builtin_expect() intrinsic as compiler micro-optimization
|
|
|
|
- Build on Intel compiler
|
|
|
|
- HTTP library now follows HTTP redirects
|
|
|
|
|
|
|
|
Version 0.7 - February 12, 2011
|
|
|
|
|
|
|
|
- Re-use CURL object, thereby reuseing DNS cache and HTTP connections
|
|
|
|
- Use bswap_32, if compiler intrinsic is not available
|
|
|
|
- Disable full target validation (as opposed to simply H==0) for now
|
|
|
|
|
|
|
|
Version 0.6.1 - February 4, 2011
|
|
|
|
|
|
|
|
- Fully validate "hash < target", rather than simply stopping our scan
|
|
|
|
if the high 32 bits are 00000000.
|
|
|
|
- Add --retry-pause, to set length of pause time between failure retries
|
|
|
|
- Display proof-of-work hash and target, if -D (debug mode) enabled
|
|
|
|
- Fix max-nonce auto-adjustment to actually work. This means if your
|
|
|
|
scan takes longer than 5 seconds (--scantime), the miner will slowly
|
|
|
|
reduce the number of hashes you work on, before fetching a new work unit.
|
|
|
|
|
|
|
|
Version 0.6 - January 29, 2011
|
|
|
|
|
|
|
|
- Fetch new work unit, if scanhash takes longer than 5 seconds (--scantime)
|
|
|
|
- BeeCee1's sha256 4way optimizations
|
|
