Author	SHA1	Message	Date
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	4868c412b0	windows: add support for SM 2.1, drop SM 3.5 (x86) ... Mostly to do compatibilty tests, SM 2.1 support is very limited SM 3.0 code should run on SM 3.5 (only a few cards use this arch) As i can't test SM 3.5, its best to let users do their own tests...	9 years ago
Tanguy Pruvot	a7d54cd7ef	blake: no need to fail on init, no big alloc	9 years ago
Tanguy Pruvot	5bf1f98200	various fixes for SM 2.1 and the benchmark ... X11+ algos and quark are not compatible for the moment but these ones are : Benchmark results for Gigabyte GTX 460 (SM 2.1 / 1 GB): blakecoin : 159090.5 kH/s, 1 MB, 1048576 thr. blake : 70208.9 kH/s, 1 MB, 1048576 thr. bmw : 122802.6 kH/s, 65 MB, 2097152 thr. deep : 3533.6 kH/s, 33 MB, 524288 thr. fugue256 : 43177.9 kH/s, 17 MB, 524288 thr. heavy : 4118.2 kH/s, 147 MB, 524032 thr. keccak : 18673.1 kH/s, 129 MB, 2097152 thr. luffa : 28816.0 kH/s, 257 MB, 4194304 thr. lyra2 : 213.7 kH/s, 570 MB, 65536 thr. mjollnir : 3895.6 kH/s, 147 MB, 524032 thr. nist5 : 1101.4 kH/s, 67 MB, 1048576 thr. penta : 501.6 kH/s, 21 MB, 327680 thr. skein : 5432.4 kH/s, 65 MB, 1048576 thr. skein2 : 6788.9 kH/s, 33 MB, 524288 thr. whirlpool : 688.5 kH/s, 33 MB, 524288 thr. zr5 : 122.5 kH/s, 86 MB, 262144 thr.	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	c6dcc5e5cf	benchmark: show mem and default throughput in results ... and prepare a new function to get the default intensity also, take care of multiple threads per gpu...	9 years ago
Tanguy Pruvot	8db5a0bc9e	blake: change dynamic round system ... blakecoin was conflicting with lyra2, set the rounds more properly	9 years ago
Tanguy Pruvot	5f12943de5	whirlpool: add algo free function + vstudio	9 years ago
Tanguy Pruvot	b641bfdf8b	diff: rename functions like cpuminer-multi ... more proper, intuitive...	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	3d3f2e2cb5	warnings: use the right device id (device_map[thr_id])	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	a66d78e692	reduce lyra2 blake and pentablake cpu load	10 years ago
Tanguy Pruvot	49a73971c4	Enhance stale work detection + throughput fixes ... seems to resolve solo mining lock on share. export also computed solo work diff in api (not perfect) In high rate algos, throughput should be unsigned... This fixes keccak, blake and doom problems And change terminal color of debug lines, to be selectable in putty, color code is not supported in windows but selection is ok there.	10 years ago
Tanguy Pruvot	c5b349e079	Add Lyra2 algo, based on Vertcoin published code ... Seems to be djm34 work, i recognize the code style ;) Code was cleaned/indented and adapted to my fork... Only usable on the test pool until 16 december 2014!	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	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	1b65cd05cc	heavy: add error checks, fix strict aliasing and linux ... The core problem was the cuda hefty Thread per block set to high but took me several hours to find that... btw... +25% in heavy 12500 with 256 threads per block... vs 128 & 512 if max reg count is set to 80...	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	73f22b237a	Prepare trap of hardware/mem failures	10 years ago
Tanguy Pruvot	b4ef7b981f	scan range: add boundary check, cant be > UINT32_MAX	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	93bb428bdf	blake: rewrite the cache system ... Unlike other hash algos, blake256 compute the hash with blocks of 64 bytes. We can do the first part on the cpu, only the 4 last int32 are computed on gpu (including the tested nonce) Previous method was also using this kind of cache with a crc. Blake Hash Speed: +5%	10 years ago
