Tanguy Pruvot	a237601747	1.7.1 release set schedule flags to reduce linux cpu usage without MyStreamSynchronize()	9 years ago
Tanguy Pruvot	e50556b637	various changes, cleanup for the release small fixes to handle better the multi thread per gpu explicitly report than quark is not compatible with SM 2.1 (compact shuffle)	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	8d4d4d65ce	cuda: header for common kernel functions (quark/x11) Was thinking about doing that since months ;) lets go	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	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	9dfa757dc7	warn on cuda errors + various small changes The full benchmark can now be launched with "ccminer --benchmark" add a new helper function which log a warning with last cuda error (not shown with the quiet option) : CUDA_LOG_ERROR(); it can be used where miner.h is included (.c/.cpp/.cu) fix x14 (in ccminer.cpp), a break was missing in switch..case	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	c2214091ae	benchmark: free last memory leaks on algo switch remains my original lyra2 implementation to fix... (cuda_lyra2.cu) I guess some kind of memory overflow force the driver to allocate memory... but was unable to free it without device reset.	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	ee93927fac	diff: use the new function in all algos	9 years ago
Tanguy Pruvot	e1c4b3042c	algos: add functions to free allocated resources Will be used later for algo switching not really tested yet...	9 years ago
Tanguy Pruvot	5308898d1c	start v1.7, apply new prototypes to all algos	9 years ago
Tanguy Pruvot	42bcb91ca0	x11: update sp luffa/cube to get closer x11 speeds.. i had to clean it... lot of unused defines...	10 years ago
Tanguy Pruvot	2113be6eec	blake80: some changes and launch bounds, no perf changes	10 years ago
Tanguy Pruvot	3d3f2e2cb5	warnings: use the right device id (device_map[thr_id])	10 years ago
KlausT	ae8e863591	remove uint32_t cast	10 years ago
Tanguy Pruvot	e6112e878d	cleanup: use unsigned throughput parameters Yes, its a big commit, was waiting 1.6 to do that... Sorry for your possible merge issues ;)	10 years ago
Tanguy Pruvot	26b51a557b	Allow different intensity per device and clean the old variables, no more required	10 years ago
Tanguy Pruvot	45206e49c1	hamsi: TPB of 128 give better results (+10kh)	10 years ago
Tanguy Pruvot	2a5233f56e	api: report throughput when default	10 years ago
Tanguy Pruvot	cafd4477d7	Handle a maximum of 16 gpus (vs 8 before) Some cards have 2 gpus on board...	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	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

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

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	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	06763c20b1	Implement x14 (cuda + cpu functions) Project was updated for VS2013 and CUDA SDK 6.5 add also a --cputest function to dump cpu hash results TODO: x15 is not fully functional, but first loop seems ok Signed-off-by: Tanguy Pruvot <tanguy.pruvot@gmail.com>	11 years ago
