Author	SHA1	Message	Date
Tanguy Pruvot	ec5a48f420	x11: small simd512 gpu_expand improvement	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... 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	8ad180cc70	various small changes ... heavy: reduce by 256 threads default intensity to all -i 20 cuda: put static thread init bools outside the code (made once) api: fix nvml header to build without	10 years ago
Tanguy Pruvot	6ae28162db	various extern cleanup + api history uids and gpu SM ... uids could be useful to create graphes from history data Note: please do a clean build after this commit (changes in miner.h)	10 years ago
Tanguy Pruvot	9b1ff1280e	Allow intermediate intensity (decimals) ... Sample with -i 18.5 Adding 131072 threads to intensity 18, 393216 cuda threads And with -i 19.5 Adding 262144 threads to intensity 19, 786432 cuda threads	10 years ago
Tanguy Pruvot	d0316220dd	simd512: restore full maxwell power (typo)	10 years ago
Tanguy Pruvot	c88750332c	simd512: restore SM3/3.5 perfs ... Simple change which affect all algos based on SIMD512 fresh, qubit, s3, x11 to x17...	10 years ago
Tanguy Pruvot	94c9945fe6	cubeluffa: Fix indent and add some static prefixes ... use git "show -w <commithash>" to see changes Duplicated functions in merged Cube+Luffa could be cross linked without	10 years ago
sp-hash	f0d91ab8a6	Luffa and simd merged to one kernal. ... Small echo rewrite. +10KHASH on the 650(compute 3.0) tpruvot: add Linux Makefile - Force to 80 registers (else -30KH/s) Note : the hashrate seems more constant with this change	10 years ago
sp-hash	7d88e5cca1	Faster Simd ... On maxwell compress1 and compress2 can be run in one run instead of two.(750TI + 20KHASH)	10 years ago
Tanguy Pruvot	73f22b237a	Prepare trap of hardware/mem failures	10 years ago
Tanguy Pruvot	bdfce54c3b	x11: restore default intensity to 19 on windows	10 years ago
Tanguy Pruvot	fe4ad36b73	intensity: sign warnings fixes min(i,u)	10 years ago
Tanguy Pruvot	c859041993	quark/blake512 opt. pointed by sp without asm ... indeed, the pragma unroll doesnt always make things faster asm part... to check later	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	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	14a41959f8	x11: switch to intensity 20 for SM>=5.2 750+970	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
sp-hash	e18a54e8fc	sp echo optimisation + cleanup ... Original Commit : Removed sharedmem and reduced calculations with precalcing (ECHO hash). 750ti + 20KHASH(x11) tpruvot notes: Real change is more of 10 KH/s on stock clocks (but real) launch bounds disabled, no perf increase with 64 registers	10 years ago
Tanguy Pruvot	b128312efb	cuda: store device SM in a global var ... sample usage made for blake and fugue (higher intensity for SM5.2) add these to cuda_helper and clean unused code	10 years ago
Tanguy Pruvot	11c5ec810d	Handle intensity param in all algos ... and add a check related to start/max nounce params	10 years ago
sp-hash	5be6811dcf	x11: echo and cubehash optimization ... echo : 40.056ms -> 39.241ms cube : 14.490ms -> 13.511ms cube hash change look like useless (__device__ code in generally inlined) but the reality proves that cuda documentation is wrong... tpruvot: fixed dos lines ending in echo, and used my style for cuda function attributes	10 years ago
Tanguy Pruvot	b191d713a0	s3: reduce a bit the intensity on windows	10 years ago
Tanguy Pruvot	6169bf683b	Add S3 Algo (1Coin) ... Simple addition of the algo using existing X11 code	10 years ago
Tanguy Pruvot	93f4409dde	simd: then reindent the code ... no changes, only error checks (cuda safe call)	10 years ago
Tanguy Pruvot	b465fe6825	optimize x11 simd512 (+100KH/s) ... change picked from tsiv repo	10 years ago
Tanguy Pruvot	1b241df5c0	cubehash and luffa funnel shit (from klaus) ... No gain... but i like this define, more readable in luffa ;)	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
Tanguy Pruvot	95ac1d0f19	x11: adapt some blake 256 opts to 512 one ... blake512: for the moment 6.2ms vs 7.12 before (+10%)	10 years ago

Tanguy Pruvot	bc2eb75758	Add fresh algo (based on djm34 code) ... Cleaned up and adapted to my changes (cputest added) Remove Makefile.in which should be in gitignore (Plz refresh it with ./config.sh to compile on linux)	10 years ago
