Con Kolivas	eea05c05b8	Update kernel with a shorter output path, and use 4k output buffer to match OS page sizes.	14 years ago
Con Kolivas	857902a13d	Commit a new phatk kernel renamed to force new binary building and add proper support in makefiles.	14 years ago
Con Kolivas	0c910673b2	Set max preferred size to 256 to prevent lying cards from crashing when no worksize is set.	14 years ago
Con Kolivas	826cc4800e	Opcode should be ULL.	14 years ago
Rusty Russell	efebee5ab8	Fix the case where there are no GPUs, and exit if they give errors. If there are no GPUs, set nDevs to 0 not -1 (status is set to an unhelpful -1001 here on my laptop, so we can't rely on a particular status value). Also, if nDevs is -1, exit rather than screwing up later.	14 years ago
Ycros	52d6e7ca37	Fixed fread issues under Windows.	14 years ago
Con Kolivas	a93b22c630	Make it possible to build without GPU mining by picking up HAVE_OPENCL from config.h.	14 years ago
Con Kolivas	821da37c84	Add hardware name to binary kernel name allowing for unique kernels for different cards on the same machine.	14 years ago
Con Kolivas	13b43cfad1	Update copyright and authors.	14 years ago
Con Kolivas	594b38b8cb	Fix redefinition of gnu source.	14 years ago
Ycros	ec8319176e	Build on windows using mingw32.	14 years ago
Ycros	5d301c8ba0	Make a binary load failure build from source.	14 years ago
Con Kolivas	3aa5be4fcf	Reinstate binary kernel loading with fixes. Build binaries with unique filenames from the kernel generated and save them. Try to load this cached binary if it matches on next kernel instantiation. This speeds up start-up dramatically, and has a unique kernel binary for different kernel configurations.	14 years ago
Con Kolivas	60f0bb19de	Temporarily back out binary building till it's working more reliably.	14 years ago
Con Kolivas	a095f0fae2	Broke source generated program. Fix.	14 years ago
Con Kolivas	4d73057772	Build binaries with unique filenames from the kernel generated and save them. Try to load this cached binary if it matches on next kernel instantiation. This speeds up start-up dramatically, and has a unique kernel binary for different kernel configurations.	14 years ago
Con Kolivas	973b2199e1	Tidy.	14 years ago
Con Kolivas	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.	14 years ago
ckolivas	1dfbe60353	Put sanity limit on work size since some nvidia fail :(	14 years ago
Con Kolivas	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.	14 years ago
Con Kolivas	2dbb39444d	Base was being set wrongly meaning we were repeating searches and the rate was actually lower than displayed :( Tweak Ma with new changes. Change default vectors to 2 since it's faster than 4 even when 4 is reported as preferred.	14 years ago
Con Kolivas	c566605195	Tab dainbramage.	14 years ago
Con Kolivas	11c8818558	32 bit only builds one elf, not an elf in an elf, so account for it to be able to bfi int patch properly.	14 years ago
Con Kolivas	623b9b9fd8	Patch bitalign separately from bfi_int. Recover from failing to patch for bfi int.	14 years ago

ckolivas	19eea9067f	Implement code detecting max work size and optimal vector width. Use this to patch the kernel to suit the idea values for the card. Then use these values when invoking the kernel.	14 years ago
