e90ade048a ndevs: get vendor names on windows too 
ccminer -n 2>NUL

GPU #0: SM 5.2 GeForce GTX 970
GPU #1: SM 5.0 Gigabyte GTX 750 Ti
GPU #2: SM 5.2 ASUS GTX 970

note: nvml destroy is made in proper_exit function

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)

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...

8fd2739a65 lyra2: support for SM 2.1 cards (GTX 460)

fc84c719e9 lyra2: improve cuda implementation (part 1, SM5+) 
based on the new djm34 method, 2x faster than first version

cleaned and tuned for the GTX 750/960 (linux / cuda 6.5)

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
 2015-10-12 08:46:13 +02:00

8fbfe2cfda add gpulog() function helper, simple and multi-threads 
when using multiple cpu threads per gpu, use the T prefix, ex:

[2015-10-11 09:52:49] GPU #0: app clocks set to P0 (3600/1228)
 vs
[2015-10-11 09:52:51] GPU T0: MSI GTX 960, 5953.35 kH/s

Only thr_id is required, the function take care of the dev id

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.

4e1e03b891 benchmark: store all algos results + cuda fixes 
Note: lyra2, lyra2v2 and script seems to have problems
to coexist with other algos... to run after some of them...

moved lyra2 first and skip scrypt/jane for the moment...

Only stored in memory for now.. to display a table after the bench

ccminer -a auto --benchmark

Results may be exported later to a json file...

42789f1a0d whirlpool: allow stratum compat with new coins

Doesn't affect solo mining, only pools using stratum+tcp:// protocol

b3adebdf2a lyra2v2: improve speed on SM 5.2 (Cuda 6.5) with sp unrolls 
Reduce a bit the 750Ti speed but improve a lot the 9xx speed.

Keep compat for SM 3/3.5 in a second file..

Note: With this code and Cuda 7.5, the speed won is the reverse...
      May be "reverted" soon
