Author	SHA1	Message	Date
Tanguy Pruvot	76a22479b1	whirlpool midstate and debug/trace defines ... + new cuda_debug.cuh include to trace gpu data Happy new year! Signed-off-by: Tanguy Pruvot <tanguy.pruvot@gmail.com>	9 years ago
Tanguy Pruvot	61ff92b5b4	never interrupt global benchmark with found nonces ... fix some algo weird hashrates (like blake) and reset device between algos, for better accuracy but this reset doesnt seems enough to bench all algos correctly... to test on linux, could be a driver issue... heavy: fix first alloc and indent with tabs...	9 years ago
Tanguy Pruvot	0d9d3520ac	simd: add support for SM 2.1 devices ... Add support for x11..x17, s3, fresh and qubit Signed-off-by: Tanguy Pruvot <tanguy.pruvot@gmail.com>	9 years ago

Tanguy Pruvot	d43dc9a021	use blake512 sp kernels on SM 5+ (80+64) ... import and keep my code for older archs, like skein 64 reduce the gap between our versions... +150kH x11 GTX 960 / +30kH 750Ti +900kH quark GTX 960 / +230kH 750Ti	9 years ago
Tanguy Pruvot	ef817df79a	import sp skein512 unrolled 64-bytes kernel (+0,6% x11) ... Quark and S3 are now a bit faster (+1 %) x11 get +0.6 % (+20kH/s on a 750ti, +30kH on a 960) 80 bytes implementation to do/test ... (skein/skein2) but keep my previous version for older devices...	9 years ago
Tanguy Pruvot	355b835ae0	benchmark: enhance the mem leak detection ... reduce "false" warnings, and ignore unrelated/small ones <= 1 MB On windows the gpu memory can be allocated by other processes + some cleanup in algos... (free/gpulog)	9 years ago
Tanguy Pruvot	d195f2e8a2	intensity: do not reduce throughput before init ... Else the memory allocated could be less than required later btw, use the new "cuda" function to apply intensity/throughput	9 years ago
Tanguy Pruvot	922c2a5cd7	algos: free allocated mem for algo switch ... All can be freed propertly now, except script (reset) and lyra2 (leak)	9 years ago

Tanguy Pruvot	c3bdb623e8	Check and submit multiple nonces in one loop ... Added to most algos, checkhash function scans a big range and can find multiple nonces at once if the difficulty is low. Stop ignoring them, submit second one if found... Clean the draft code for rc=2 implemented for blake and pentablake btw... fix the reduced displayed hashrate when a nonce is found... Signed-off-by: Tanguy Pruvot <tanguy.pruvot@gmail.com>	10 years ago
Tanguy Pruvot	f387898ead	Prepare multiple nonces support in one loop (if found) ... Tested on x11 which find sometimes 3 nonces in one call, actually they are ignored because only the biggest was kept... This commit doesnt fix that, but will allow to enhance shares rate later...	10 years ago
Tanguy Pruvot	118a6be361	checkhash: simplify the common function ... use klaus trivial function, the old code has always been a bit weird.. split cuda_check_cpu_hash_64 in two functions, keep old for branched stuff	10 years ago

Tanguy Pruvot	438308b3a2	Rework benchmark mode and min/max range ... Was maybe my fault, but the benchmark mode was always recomputing from nonce 0. Also fix blake if -d 1 is used (one thread but second gpu) stats: do not use thread id as key, prefer gpu id...	10 years ago

Tanguy Pruvot	d8a23fa970	Tune quark part of Xn funcs ... based on klaus commits, will increase a bit speed of most algos PS: main increase is due to the register count tuning in Makefile and for skein512 on linux, its the ROTL64 but almost no changes on X11 : 2648MH/s vs 2630 before	10 years ago
Tanguy Pruvot	7cc5222394	Move common check_cpu functions to root	10 years ago
