639d38fbd4 Revert "Make sure to give work items a starting time only once when they're staged." 
This reverts commit 626ae10d7c.

Failed to address all work items.

28880d0dc7 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.

947a74bfa3 Differentiate thread failure from GPU failure by declaring a GPU sick first and trying to restart the thread without re-initialising the card. 
If that fails, then try once more at ten minutes and declare it dead.
This should prevent an attempted re-initialising of the GPU from taking out other GPUs.

3803760689 Reimplement the per-thread getwork count with proper accounting at get_work(). 2011-07-29 11:11:42 +10:00

0fe22d8d94 Revert "Only update the thread getwork queue count if it actually results in a getwork request from the server." 
This reverts commit 2e607d44f2.

The count looks far too difficult to add up with this change since many are queued generically.

e82e390295 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. 2011-07-27 16:40:52 +10:00

1536e085da 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).

7707ed4db1 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.

c9bbaec3b2 Cope with delays in retrieving work from the server by knowing when we have run out of staged work. 
Once we are out of staged work, roll the ntime forwards in the work to generate work locally without a getwork.
Display a message explaining when we move to/from local generation to server retrieval.
Make sure we don't think we've run out of work transiently after a longpoll by flagging a buffer of fake staged work.
