Hi guys, I want to get together a group of PCs with several GPUs each, I've a couple of questions.
1) What's the real world difference between cracking with or without Inifiniband? Which percentage of cracking power do you lose if you use gigabit ethernet cables vs using Infiniband? Is it dependant on the hash cracked?
2) Does the VCL/oclHashcat-plus combo supports computers with different GPUs models or do they need to be the exact same chip?
3) Is the PCI-e port speed important? Some motherboards have the GPUs connected via a cable, that goes to the 1x PCI-e port. For bitcoin mining, that's allright. Would I lose any speed when hash cracking?
Thanks guys!
