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...

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...

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)

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

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

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...
