Author	SHA1	Message	Date
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	1187a6e7e3	x11: improve aes (shavite/echo) ... shavite is faster, echo doesn't really change due to the reg. overload This changes allow custom lauchbounds without other code changes and improve the portability against different devices. also set a minimum throughput to 1024 for these algos (shared mem req. size)	10 years ago
Tanguy Pruvot	9f5744d4c0	luffa/cube: fine tuning of maxregcount for the 750Ti ... This allow to get 69 regs used (tested on linux) 69 or 72 make the compiler to use 64 regs which is not enough on the 750Ti for optimal performance...	10 years ago

Tanguy Pruvot	6c7fce187b	x11: use KlausT optimisation (+20 KHs) ... But use a define in AES to use or not device initial memcpy I already tried to use everywhere direct device constants and its not faster for big arrays (difference is small) also change launch bounds to reduce spills (72 regs) to check on windows too, could improve the perf... or not	10 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...

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	11dbbcc12d	checkhash: some work on a faster variant (wip) ... This should not be used for all algos... not enabled yet todo: multiple nounces or blake32 style checkup	10 years ago

Tanguy Pruvot	fdd5d29071	x11: shavite and echo from sp (now ok on win32) ... Previous echo commit was only increasing linux performance, and reducing windows perf compared to the 1.4.9, this one seems to give at least the 1.4.9 on windows, and the same on linux... Shavite optimisation seems ok on both (use now 64 registers) the launch_bounds will force the number of registers, so remove specific Makefile rules on linux... manual "cherry pick" with fixed line endings and some adaptations	10 years ago
