    Thread: Infiniband GPU cluster
Post: RE: Infiniband GPU cluster

AFAIK, no. The only way to parallelize pluscat or any other cat is to write a script that will split the workload and assign work to every GPU over the network. Or write some kind of framework. A...

    Thread: Fastest Nvidia driver for hash cracking?
Post: RE: Fastest Nvidia driver for hash cracking?

The trend is a good observation, it depends on the CUDA toolkit used for compilation of oclhc too. Anyways, I personally use some stable forceware (347.25) and don't bother updating it unless new ocl...

NV has done something to either the driver, or to the cuda 5.0 toolkit. Litecat, v0.10 release vs 0.11b20 is always a bit slower in all algos, except LM and old oracle 7-10g. Rolling back to good ol...

Even though hashcat is free software, it's not open source. This may or may not change at some point in the future. Closed.

It's explained in the error, but I'll rephrase it: your GPU is too old to be used by cudahc.

I may be wrong, but rendering graphics has nothing to do with OpenCL code. Also, in my opinion, the hard way is not the best way.

Only hashcat and litecat support restore. The max length of 15 exists for optimization(speed) purposes.

You need to understand how mirrored hashes work. For example, you have a sha512($pass.$salt) algorithm, so in order to brute force the salt you'd need to use sha512($salt.$pass), and configure the ...
