DCC2 - 2100 only using one GPU on multi GPU systems

[bkuzma]

what attack type (-a x) ? What input ? How large is the mask/dict(s) ?

Maybe try using this:

Code:

-S

but the speed will/could suffer a lot with -S.

I guess you could just optimize your attack, also read: https://hashcat.net/faq/morework

I had it running through a relatively small password list with the OnePasswordToRuleThemAll rule applied. Across the entire cluster, it was pushing around 1000 hashes/sec. 

After looking at it again, and eyeballing the portion of the FAQ you linked, I killed the job and started a -a3 with ?a?a?a?a?a?a?a?a as the mask. The total hashrate's jumped and all the GPUs are now fully utilized. 

Am I correct in inferring that I accidentally starved Hashcat of workload?
