Subject: CUDA running on multiple cards
I'm hammering you with GPU questions now :)
What would it take to make use of multiple graphic cards in one JtR
session? Would that need a complete re-write and a new design, or do you
get some things "for free" or with help from the toolkit (like in OMP,
where we just add a #pragma and voila, we have parallel processing)?
And second, isn't there any kind of resource protection? I tried running
cRARk and then started a John session. The cRARk session died (out of
memory) and the John session crashed.
Could a format detect that there are multiple cards, and pick one that
is not already used?
If nothing else, I'd like CUDA to support the --gpu=N option that OpenCL
has in JtR, if possible. cRARk lacks that option btw, it always runs on
first card.
