8bd8696854 The work struct pointer in struct pc_data in findnonce is never freed yet there is no need to allocate it separately so make struct work a static part of the struct pc_data.

1c070475c3 Cycling over 1026 nonces is a remnant of old code not relevant now and can just lead to repeat submission of the same block increasing rejects.

d5d4d1da16 Don't want to free the work data out of the transient structs. 2011-07-04 19:47:46 +10:00

2b6e841673 Use a buffer of up to 512 * 4 integers when retrieving work from the GPU. 
This allows each local thread id to have one slot to put any positive results into, thus making overlapping results far less likely.
Thus races will be much rarer, allowing more threads.
It should also pick up blocks close to each other more reliably and hopefully decrease the number of rejects and opencl errors.
Do the search over the buffer entirely in a separate thread to allow the GPU to stay as busy as possible.
Detach threads from themselves to prevent unlucky even where dereferencing occurs by freeing the data that stores the thread info.

6374e0fafe Import the phatk kernel. Enable it only for hardware with amd media ops for now since it crashes nvidia et. al. 
Fallback to the poclbm kernel for the rest. Try harder to avoid stale blocks around longpoll detecting new blocks.
