Con Kolivas	25bebf3b92	Make the output line much terser now that it has a lot of information on it.	14 years ago
Con Kolivas	ed233e8cb5	Put work into a staging area which makes it possible to check the latest work data received. Then check the latest work data against a store of the current_block and use it to determine if we have moved to a new block. This makes --no-longpoll work just as efficiently as longpoll, and works around when longpoll is unreliable.	14 years ago
Marco Fontani	c815de4991	Add "efficiency" and "utility" Efficiency is the percentage of getworks compared to the amount of work requested from the pool. It can go higher than 100% in case more shares than getworks were found. Some pools prefer miners to have a high efficiency; CPU miners likely exhibit a low efficiency. Utility is the number of shares found per minute, since the miner was started. It is another way to describe the effectiveness of a miner.	14 years ago
Rusty Russell	efebee5ab8	Fix the case where there are no GPUs, and exit if they give errors. If there are no GPUs, set nDevs to 0 not -1 (status is set to an unhelpful -1001 here on my laptop, so we can't rely on a particular status value). Also, if nDevs is -1, exit rather than screwing up later.	14 years ago
Rusty Russell	8b68dc44d4	Fix --ndevs/-n option. The option should be called from within the callback, and just use printf to give the raw result, rather than using applog which prepends a timestamp.	14 years ago
Rusty Russell	8d25df3c72	Cleanup --cpu-threads/-t logic Currently it gets negated which means the default printed is wrong. Use an explicit flag to tell if the user has overridden it; if they haven't, and they turn off the GPUs, reset it to num_processors.	14 years ago
Rusty Russell	3e8181216c	Use ccan/opt for commandline parsing. This cleans up option handling, by using ccan/opt rather than handcoded getopt_long. We still have to open-code some things, such as json config file handling. The main change is that the --config option causes a file to be parsed during commandline parsing, so you can override the results, and provide multiple of them. Other improvements are that 'help' and 'ndevs' are not valid arguments in the config file; we use a separate argument table for such commandline-only flags.	14 years ago
Con Kolivas	5969d65a04	First work for each thread is now queued in advance.	14 years ago
Con Kolivas	e9a397d4b9	More space to wipe old text.	14 years ago
Con Kolivas	e99069808a	Fix the extra work queued every longpoll by queueing it all in the beginning.	14 years ago
Con Kolivas	719deb3aac	Create a wakeup thread that keeps the hashmeter going in case the mining threads all stall.	14 years ago
Con Kolivas	ddae5aa9d0	Remove unused variable.	14 years ago
Con Kolivas	837e7b1a85	Remove unused cgpu rolling_local variable.	14 years ago
Con Kolivas	93800e5790	More output tidy.	14 years ago
Con Kolivas	56eee5f007	Retry should get_work() fail for whatever reason.	14 years ago
Con Kolivas	07f6de8b34	Change ifdef order since batch is always defined if idle is.	14 years ago
Con Kolivas	cf1e4627e4	Give error messages at all points of failure.	14 years ago
Con Kolivas	ed7e5bf9a3	There is still potential for an uneven number of queued and dropped work items with this unnecessarily complex check. Flush work guarantees a symmetrical number of queue and discard already.	14 years ago
Con Kolivas	69d8df643a	More cleaning of output with detecting new block.	14 years ago
Con Kolivas	8333a2ff40	Improve output appearance +/- verbose mode.	14 years ago
Con Kolivas	1fb09eaa0e	Implement -n/--ndevs option.	14 years ago
Con Kolivas	0ebdc39a19	Make debug mode imply verbose mode.	14 years ago
Con Kolivas	413e6b8645	Fix potential divide by zero.	14 years ago
Con Kolivas	0a80d4b04d	Display the output as a refreshing line and only push continuous log to stderr if desired.	14 years ago
Con Kolivas	a93b22c630	Make it possible to build without GPU mining by picking up HAVE_OPENCL from config.h.	14 years ago
Con Kolivas	4172fec24a	Cope with invalid parameter passing.	14 years ago
Con Kolivas	bc7cde7b36	Implement short option parsing.	14 years ago
Con Kolivas	13c57a5779	Properly initialise qd_lock mutex.	14 years ago
Con Kolivas	f90e73af51	Queue and pop precisely the same amount of work in flush_request to ensure all work is cleared and there isn't an uneven add/remove possible.	14 years ago
Con Kolivas	af6e7937ca	Signal handling in dns lookup code is responsible for libcurl crashes when multithreading. Disable signal handling and use many curl handles instead, thus making work more asynchronous. Theoretically a curl can wait forever on a dns lookup with this but it's extremely unlikely.	14 years ago
Con Kolivas	91f9c527ba	Rename code and application binary to cgminer version 1.0.9 preempting version 1.1.0, moving main code to main.c.	14 years ago
Con Kolivas	8f098e4ab4	Put locking around the queued count to ensure we're never left without work.	14 years ago
Con Kolivas	122f0cf260	With pre-emptive queueing of work there is no need to have extra work in the queue by default. Make it a list of extra queue items instead of a total and default to 0.	14 years ago
Con Kolivas	5cbc33e756	Change default retry to 5 seconds.	14 years ago
Con Kolivas	de3d07d13b	Make the next work item queue 2/3 of the way through the work on the current work item. Load the first queued extra work in the main function to avoid having a once-off variable in get_work(). Load an extra set of work for each function in advance once a longpoll is detected since every thread will need to get new work. Discard requests with a separate function to ensure the right number is always queued.	14 years ago
Con Kolivas	ad787e1c2a	Move the flushing of old work into restart threads so it's done before any worker threads grab more work.	14 years ago
Con Kolivas	5007805d1f	Update CPU reentrant scan code to work properly for extended periods up to scantime and adjust rate properly. Simplify locking in hashmeter since it's called relatively infrequently anyway. Set gpuminer hashmeter interval update to log interval / 5 as well.	14 years ago
Con Kolivas	e4f9ea68a9	CPU mining is spending too much time in the work thread and not receiving restart messages. Update the code to return at log interval / 5 and only get work at the right time.	14 years ago
Con Kolivas	8999bea110	People expect miners to run indefinitely instead of giving up by default so change to never giving up if json call fails.	14 years ago
Con Kolivas	9f726400d4	Logic error in the queueing of work ended up generating more stale blocks. There is a small chance that a longpoll is signalled right at the start which would lead to a deadlock so check for first work before restart.	14 years ago
Con Kolivas	594b38b8cb	Fix redefinition of gnu source.	14 years ago
Ycros	9fe2106467	Fixed up using config.h instead of cpuminer-config.h.	14 years ago
Con Kolivas	edd0591e19	Make the number of queued work items configurable and default to 2.	14 years ago
Con Kolivas	131f60a5ee	Move queueing of one request to separate function in preparation for variable length queues.	14 years ago
Con Kolivas	ffdffe77d3	Make sure the work gets attributed to the correct gpu. Add an fflush to stderr to minimise garbled output when multiple threads write at once.	14 years ago
Con Kolivas	86e40ed9c8	Stale block control makes it possible to make 2 threads per gpu the default again.	14 years ago
Con Kolivas	48caf248a7	Check for stale block after failed submission as well.	14 years ago
Con Kolivas	09104ce3e8	Flag the work back to just thread 0 used by all the threads to avoid lots of queued older work for each thread.	14 years ago
Con Kolivas	bed692152f	Get rid of the requirement for a static struct that needs locking to cache work. Make it possible to use the thread id for getting work again. Flag the getwork() function when we have a new block to explicitly discard any cached work when a new block is detected. Store the header of each new work and compare it to blocks we're about to submit to decide if they're stale due to a new block and don't try to submit them. This should significantly decrease the number of rejected blocks.	14 years ago
Con Kolivas	e2fb3e84cb	Queueing all kernel parameters dramatically reduces stale block rates.	14 years ago
