Version 2.7.0 - August 18, 2012 |
|
|
|
|
|
|
|
|
|
- Introduce a new statistic, Work Utility, which is the number of difficulty 1 |
|
|
|
|
shares solved per minute. This is useful for measuring a relative rate of work |
|
|
|
|
that is independent of reject rate and target difficulty. |
|
|
|
|
- Implement a new pool strategy, BALANCE, which monitors work performed per pool |
|
|
|
|
as a rolling average every 10 minutes to try and distribute work evenly over all |
|
|
|
|
the pools. Do this by monitoring diff1 solutions to allow different difficulty |
|
|
|
|
target pools to be treated equally, along with solo mining. Update the |
|
|
|
|
documentation to describe this strategy and more accurately describe the |
|
|
|
|
load-balance one. |
|
|
|
|
- Getwork fail was not being detected. Remove a vast amount of unused variables |
|
|
|
|
and functions used in the old queue request mechanism and redefine the getfail |
|
|
|
|
testing. |
|
|
|
|
- Don't try to start devices that don't support scrypt when scrypt mining. |
|
|
|
|
- 0 is a valid return value for read so only break out if read returns -1. |
|
|
|
|
- Consider us lagging only once our queue is almost full and no staged work. |
|
|
|
|
- Simplify the enough work algorithm dramatically. |
|
|
|
|
- Only queue from backup pools once we have nothing staged. |
|
|
|
|
- Don't keep queueing work indefinitely if we're in opt failover mode. |
|
|
|
|
- Make sure we don't opt out of queueing more work if all the queued work is |
|
|
|
|
from one pool. |
|
|
|
|
- Set lagging flag if we're on the last of our staged items. |
|
|
|
|
- Reinstate clone on grabbing work. |
|
|
|
|
- Grab clones from hashlist wherever possible first. |
|
|
|
|
- Cull all the early queue requests since we request every time work is popped |
|
|
|
|
now. |
|
|
|
|
- Keep track of staged rollable work item counts to speed up clone_available. |
|
|
|
|
- Make expiry on should_roll to 2/3 time instead of share duration since some |
|
|
|
|
hardware will have very fast share times. |
|
|
|
|
- Do the cheaper comparison first. |
|
|
|
|
- Check that we'll get 1 shares' worth of work time by rolling before saying we |
|
|
|
|
should roll the work. |
|
|
|
|
- Simplify all those total_secs usages by initialising it to 1 second. |
|
|
|
|
- Overlap queued decrementing with staged incrementing. |
|
|
|
|
- Artificially set the pool lagging flag on pool switch in failover only mode as |
|
|
|
|
well. |
|
|
|
|
- Artificially set the pool lagging flag on work restart to avoid messages about |
|
|
|
|
slow pools after every longpoll. |
|
|
|
|
- Factor in opt_queue value into enough work queued or staged. |
|
|
|
|
- Roll work whenever we can on getwork. |
|
|
|
|
- Queue requests for getwork regardless and test whether we should send for a |
|
|
|
|
getwork from the getwork thread itself. |
|
|
|
|
- Get rid of age_work(). |
|
|
|
|
- 0 is a valid return value for read so only break out if read returns -1. |
|
|
|
|
- Offset libusb reads/writes by length written as well in ztex. |
|
|
|
|
- Cope with timeouts and partial reads in ztex code. |
|
|
|
|
- fpga serial I/O extra debug (disabled by default) |
