Possible issue with charset and multi gpu system

[mrleau]

Hi,

I'm getting different behaviour when running on two different computers with the following command:

Code:

cudaHashcat-lite64.exe -o out.txt -s 0 -l 65610000 --pw-min 4 --pw-max 4 -m 1400 F6F2EA8F45D8A057C9566A33F99474DA2E5C6A6604D736121650E2730C6FB0A3 -1 "1234567890qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM~@#$%^&*()_+{}:|<>,./;'[]\-=" ?1?1?1?1

Computer 1: Win7 64b with GT 430 driver ver nvidia 285.62
Works fine

Computer 2: Win7 64b with 8x GTX580 driver ver nvidia 285.27
It will write the plaintext to out.txt but will keep running

Below is the console output:

Code:

C:\ProgramData\BOINC\slots\0 - Copy\oclHashcat-lite-0.09>cudaHashcat-lite32.exe

It gets stuck at the last line or if I don't press s it will keep running for ever.

After playing with the parameters I discovered that removing -= from charset made it work on both computers but it doesn't make sense to me.

Code:

cudaHashcat-lite64.exe -o out.txt -s 0 -l 65610000 --pw-min 4 --pw-max 4 -m 1400 F6F2EA8F45D8A057C9566A33F99474DA2E5C6A6604D736121650E2730C6FB0A3 -1 "1234567890qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM~@#$%^&*()_+{}:|<>,./;'[]\" ?1?1?1?1

I don't have these issues with version 0.08

BTW if you wonder I'm playing with distributed hashing and trying to make it cracker independent that's why the parameters are like that.
