Comparaison CudaHashcat-plus 0.08 vs 0.07 ... !!!

[hasheponge]

@ALL for users who use cudahashcat-plus, i tested 0.07 and 0.08 with same script... same files and same rule, same GPU !
differents performances ! and the worst not the same result !!!!

Results :

with 0.07 :

Speed........: 612.6M c/s Real, 582.8M c/s GPU
Recovered....: 311/1441897 Digests, 0/1 Salts
Progress.....: 20132793600/80453034400 (25.02%)
Rejected.....: 4420537600/20132793600 (21.96%)

with 0.08 :

Speed........: 472.3M c/s Real, 485.6M c/s GPU
Recovered....: 7/1441897 Digests, 0/1 Salts
Progress.....: 20444744960/80453034400 (25.41%)
Rejected.....: 4420537600/20444744960 (21.62%)

0.08 -23% !! and curious Recovered !!! 0.07 = 311, 0.08 = 7 !!!

Drivers 296.10
Hashs : MD5 , Rule : d3ad0ne.rule
GPU for this test : GTX 470 , win 7-32bits

... Bug ?

I tested with my second GPU (GTS 450) same results... :-(

** on this test same GPU-Loops, GPU-Accel...

I tried to reproduce your case with my own made files on AMD and on NVidia, using multihash MD5 cracking, rule-based. But I am unable to reproduce!

Maybe you can share all the required files to reproduce?

[hasheponge]

ok Atom i pm you all informations for this test . Thanks

[atom]

OK, thanks for the files. I got them. Here is the result from oclHashcat-plus v0.08:

AMD hd7970:

Speed........: 1029.1M c/s Real, 1203.9M c/s GPU
Recovered....: 1138/1441897 Digests, 0/1 Salts

See what happens to the speed after I've added -n 160 and --gpu-loops 1024:

Speed........: 2175.4M c/s Real, 2216.0M c/s GPU
Recovered....: 1138/1441897 Digests, 0/1 Salts

Now the NVidia gtx560Ti:

Speed........: 269.0M c/s Real, 271.7M c/s GPU
Recovered....: 1138/1441897 Digests, 0/1 Salts

Again, after I've added -n 160 and --gpu-loops 1024:

Speed........: 380.3M c/s Real, 394.3M c/s GPU
Recovered....: 1138/1441897 Digests, 0/1 Salts

Then I tried with the NVidia gtx560Ti with -n 160 and --gpu-loops 1024 but on oclHashcat-plus v0.07:

Speed........: 554.9M c/s Real, 516.2M c/s GPU
Recovered....: 1138/1441897 Digests, 0/1 Salts

So you are right, it is slower. But the important part, the number of cracked hashes is the same. I can not explain why this happens on your card, but I can not reproduce it. The speed drop itself must be because of the CUDA 4.2 and not because of a code change since I did not change anything on there.

thanks Atom, strange strange for the number of cracked hashes... i try install a last Cuda 4.1.28 32 bits. And test... wait.

it's crazy !
same results on GTX 470 or GTS 450

0.08 :

Speed........: 444.6M c/s Real, 425.9M c/s GPU
Recovered....: 3/1441897 Digests, 0/1 Salts
Progress.....: 8216719872/80453034400 (10.21%)

0.07 (+ fix 0.071)

Speed........: 661.2M c/s Real, 660.4M c/s GPU
Recovered....: 159/1441897 Digests, 0/1 Salts
Progress.....: 8399222240/80453034400 (10.44%)

i don't know what... :-(
