ed3eb5771a 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. 2012-08-18 15:44:48 +10:00
Con Kolivas
26ab7346e3 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.

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
