Infiniband shall give lower latency & CPU utilization and better
real-world throughput, so that's probably better Lnet-wise.
But Infiniband gears are more expensive so if taking budget into
account, 100G Ethernet may work good-enough allowing saved cost be used
to upgrade other parts of the
With the growth of 100G ethernet, is it better to connect a lustre file
server via EDR 100G Infiniband or 100G Ethernet for a 32 node HPC cluster
running a typical life sciences - Genomics workload?
Thoughts anyone?
