Hi, all My boss wants me to test a bunch of gigabit ethernet cards of a cluster. He kept getting time-out problems when running some MPI jobs on the cluster. The problem only happens when the network traffic is very high (~100MB/s). Therefore, he wants me to determine which ethernet card(s) is/are having the problem when the traffic is high. (We don't get any useful information from syslog or the log files of MPI jobs.)
I've seen people testing the ethernet card using nc (netcat) -- just transfer some files using nc and then compare them. Is there any better way to do this, or any suggestions about some existing softwares which can automate this, for I have to test a bunch of them? Thanks a lot. -- Best regards, James He
