df5d196f9a Must unlock mutex if pthread_cond_wait succeeds. 2012-07-02 12:37:15 +10:00

fd7b21ed56 Use a pthread conditional that is broadcast whenever work restarts are required. Create a generic wait function waiting a specified time on that conditional that returns if the condition is met or a specified time passed to it has elapsed. Use this to do smarter polling in bitforce to abort work, queue more work, and check for results to minimise time spent working needlessly. 2012-07-02 10:54:20 +10:00

This reverts commit 522f620c89b5f152f86a2916b0dca7b71b2a5005.

Unrealistic. Limits are bitcoind related to 2 hours in the future.

21a23a45d7 Work around pools that advertise very low expire= time inappropriately as this leads to many false positives for stale shares detected. 2012-06-27 10:15:57 +10:00

d3e2b62c54 Change sick/dead processing to use device pointer, not gpu array. 
Change BFL timing to adjust only when hashing complete (not error/idle etc.).
