Con Kolivas 86d5377e 2012-08-23T10:48:15 Use atomic ops to never miss a nonce on opencl kernels, including nonce==0, also allowing us to make the output buffer smaller.
Con Kolivas 1b5c676d 2012-07-21T11:00:36 Use 256 output slots for kernels to allow 1 for each worksize.
Con Kolivas 02e126f4 2011-08-23T10:28:30 The worksize was unintentionally changed back to 4k by mistake, this caused a slowdown.
Con Kolivas bd79a61c 2011-08-19T17:20:49 Move poclbm to new branch optimisation as well.
Con Kolivas cf54f9b8 2011-08-17T16:07:15 Move to 256 sized buffers and don't risk overwrite by using only 127 mask.
Con Kolivas 0f782ba6 2011-08-17T15:47:18 Update poclbm kernel to FF sized mask and only check that range.
Con Kolivas eea05c05 2011-07-15T13:04:25 Update kernel with a shorter output path, and use 4k output buffer to match OS page sizes.
Con Kolivas cb13e2cf 2011-07-05T19:47:03 Make it possible to build without opencl for cpu mining only.
Con Kolivas 2b6e8416 2011-06-29T23:38:16 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.
ckolivas e1dd27c5 2011-06-29T11:19:43 Ensure that we don't overflow due to 32 bit limitations.
Con Kolivas a45c54aa 2011-06-27T11:31:05 Make postcalc_hash asynchronous as well.
Con Kolivas f117675a 2011-06-22T10:15:23 Optimise work loop to make cl calls asynchronous where possible.
ckolivas 6b77d850 2011-06-17T14:00:41 Fixes.
Con Kolivas dde70397 2011-06-14T10:32:54 Merge gpumining from oclmine. Unstable.
