Excluding the CUDA/GPU versions:
• Linux-x86_64-multicore (64-bit Intel/AMD single node)
• Linux-x86_64 (64-bit Intel/AMD with ethernet)
• Linux-x86_64-TCP (TCP may be better on gigabit)
• Linux-x86_64-ibverbs (InfiniBand via OpenFabrics OFED, not for Omni-Path, no MPI needed)
• Linux-x86_64-ibverbs-smp (InfiniBand plus shared memory, no MPI needed)
Multicore is listed as single-node for a single server, and all others above are multi-node. I ended up using ibverbs-smp since I have Infiniband available. I’ve used the TCP one for testing, but it didn’t scale well at all across multiple nodes.

I would appreciate any information in this regard…If a binary was built for GPU’s it can’t be used for strictly CPU machines..right?
