Infiniband GPU cluster - aleph - 03-30-2012 Looking to build an Infiniband GPU cluster on the cheap if this is possible. Does hashcat allow for GPUdirect RDMA calls from one GPU to another to form a scalable cluster for password recovery or am I expecting too much? Alternatively, has anybody tried MPI under IPoIB for a cheap 10/20/40gb interconnect fabric? My company just literally threw out a whole bunch of IB gear, TopSpin switches and a bunch of HCA cards. I figure I'll get some cheap Intel PRO cards and boot my servers via PXE to load rocks+OFED drivers and hashcat. No clue how I'm going to do storage though. Let me know if I'm being completely off the wall here and I'll shut up. RE: Infiniband GPU cluster - Rolf - 03-30-2012 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. Anyways, this requires custom solution(s). |
