Dear Users:
I have some questions about hardware for a cpu/gpu purchase and I would
appreciate some insight. Basically, I don't really understand the ins and
outs of peer-to-peer GPU communication and I need some help.
1. What hardware specifications are required to enable peer-to-peer GPU
communication for pmemd?
2. Given 2 or 4 Pascal P100's or GTX-1080's how much is gpu-to-gpu nvlink
(without possible gpu-to-cpu nvlink) going to affect performance of
multi-gpu runs? -- Note that I realize P100's are excessivly expensive per
flop compared to GTX-1080's.
Thank you very much for your help.
Chris.
