This will allow later more gpu candidates.
Note: This is an unfinished work, we keep the previous behavior for now
To finish this, all algos solutions should be migrated and submitted nonces attributes stored.
Its required to handle the different share diff per nonce and fix the possible solved count error (if 1/2 nonces is solved).
also known as "Thor's Riddle"... yes sure ;)
Credits to ocminer who found and "implemented" it.
Note: tested "ok" on x64 and CUDA 6.5 x86, not on 7.5 and 8.0 x86
PS: Don't have the time for a more proper CUDA implementation of Streebog
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...
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
Quark and S3 are now a bit faster (+1 %)
x11 get +0.6 % (+20kH/s on a 750ti, +30kH on a 960)
80 bytes implementation to do/test ... (skein/skein2)
but keep my previous version for older devices...
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)
shavite is faster, echo doesn't really change due to the reg. overload
This changes allow custom lauchbounds without other code changes and improve
the portability against different devices.
also set a minimum throughput to 1024 for these algos (shared mem req. size)
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
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...

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...
