oclhashcat 21 speed reduction - c4p0ne - 06-24-2010
I just upgraded from 18 all the way to 21 and i've dropped down to a FRACTION of the speed. Now (with one nvidia 275 and one 260) i can barely do 100m hashes per sec with BOTH cards where with 18 i was doing over 900m hashes per sec.
wth happened????????????
RE: oclhashcat 21 speed reduction - c4p0ne - 06-24-2010
Welp, just upgraded to the latest bleeding edge nvidia drivers 257.21 (CUDA 3.1.1) and still get about 112m md5 per second. Abysmal compared to 900m+. Perhaps I'm doing something wrong, some new config option?
I should mention my hashlist is hovering around 4 million hashes (md5).

please paste speed of v0.18 with this command:
oclHashcat.exe example.hash -1 ?l?d ?1?1?1?1 ?1?1?1?1 -n 8
and of v0.21 with this command:
oclHashcat.exe example.hash -1 ?l?d ?1?1?1?1 ?1?1?1?1 -n 8 --gpu-loops 1024

The speed it exactly the same for both (>1000m/sec) which is good. I've discovered that it is the size of my md5 hashlist that is slowing oclhashcat down TREMENDOUSLY. 3 million hashes slow it down to a crawl of 100m/sec when i chop the list in half to 1.5 million hashes, the speed jumps up to 500m/sec, etc... This was not the case with .18.

Latest OCLHC is optimized to handle up to 0.5M hashes.

Hmm, it was becoming apparent that the latest version was optimized for lower numbers of hashes. Guess that gives me a reason to keep the old versions around then....

fixed in v0.23
