even faster after small modification
none@...e ~/Desktop/rr_coal_2/run $ ./john --test --format=argon2i-opencl
Benchmarking: argon2i-opencl [Blake2 OpenCL]...
memory per hash : 1000.00 kB
Device 0: GeForce GTX 960M
using different password for benchmarking
DONE
Speed for cost 1 (t) of 3, cost 2 (m) of 1000, cost 3 (l) of 1
Many salts: 2133 c/s real, 2118 c/s virtual
Only one salt: 2118 c/s real, 2133 c/s virtual
again the same problem as with yescrypt, it's auotuned properly after
I divided MEM_SIZE / 4 here:
opencl_init_auto_setup(SEED, 0, NULL,
warn, 4, self, create_clobj, release_clobj, MEM_SIZE/4, 0);
