4f43abb402 bmw512: indent and restore SM 3.0 compat
could be also the source of the problem seen with CUDA 7

restored the code before sp/klaus changes for SM 3.0 devices...

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...

f387898ead Prepare multiple nonces support in one loop (if 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...

118a6be361 checkhash: simplify the common function
use klaus trivial function, the old code has always been a bit weird..

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)

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

c88750332c simd512: restore SM3/3.5 perfs
Simple change which affect all algos based on SIMD512

fresh, qubit, s3, x11 to x17...

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

c859041993 quark/blake512 opt. pointed by sp without asm
indeed, the pragma unroll doesnt always make things faster

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...

d8a23fa970 Tune quark part of Xn funcs
based on klaus commits, will increase a bit speed of most algos

PS: main increase is due to the register count tuning in Makefile

and for skein512 on linux, its the ROTL64

but almost no changes on X11 : 2648MH/s vs 2630 before
