Hello again ;),
after getting acceptable latency on our Chelsio S320E-CXA adapters we
now want to check if we can
also tune the bandwidth. On TCP level (measured via iperf) we get 1.15
GB/s, on MPI level (measured
via MPI-Ping-Pong) just 930 MB/s. We already set btl_tcp_sndbuf and
btl_tcp_rcvbuf to get these
value. Are there any other parameters which should be in-/decreased to
get a higher bandwidth?
If someone has already experiences in it, any help is welcome!
Thanks and best regards
Andy
Are you using Chelsio's TOE drivers? Or just a driver from the distro?
