Re: VanitySearch (Yet another address prefix finder)

Look to:

GPU/GPUEngine.h

Code:

// Number of thread per block
#define NB_TRHEAD_PER_GROUP 128

try increase it to 256 or 512..

Code:

>VanitySearch-1.1.5_th128gr -t 0 -gpu 12345689
GPU: GPU #0 GeForce GTX 1070 (15x128 cores) Grid(120x128)
549.958 MK/s (GPU 549.958 MK/s) (2^33.98) [P 1.88%][50.00% in 00:18:09][0]

>VanitySearch-1.1.5_th256gr -t 0 -gpu 12345689
GPU: GPU #0 GeForce GTX 1070 (15x128 cores) Grid(120x256)
664.534 MK/s (GPU 664.534 MK/s) (2^34.08) [P 2.02%][50.00% in 00:14:59][0]

>VanitySearch-1.1.5_th512gr -t 0 -gpu 12345689
GPU: GPU #0 GeForce GTX 1070 (15x128 cores) Grid(120x512)
710.364 MK/s (GPU 710.364 MK/s) (2^34.35) [P 2.43%][50.00% in 00:13:56][0]

hashrate diff:
664/549 = x1,20
710/549 = x1,29

how about -g argv?
120x512=61440
480x128=64440
but it not equal:

Code:

>VanitySearch-1.1.5_th128gr -t 0 -gpu -g 480 12345689
GPU: GPU #0 GeForce GTX 1070 (15x128 cores) Grid(480x128)
566.206 MK/s (GPU 566.206 MK/s) (2^32.40) [P 0.64%][50.00% in 00:17:57][0]

-g is useless for it, recompilation is necessary

recompiled, non-official build from me (while Jean_Luc thinks what to do)
