Multi-device table generation

Postby cbx » Fri Dec 17, 2010 7:58 pm

Is it possible to generate a rainbow table across multiple cards (in the same machine)? For example, say I want to make a NTLM table composed of 500 tables. Would it be possible to distribute the workload evenly across all 3 of my cards?

I have 3 Tesla C2050's and 27 GTX 480's that I would really like to put to work.

You'd have to generate parts separately and merge them together.

If you have multiple GPUs in a box, run separate tasks with '-d 0', '-d 1', '-d 2' as command line parameters to select the device ID.
