Hi,

  I am mainly using MPICH via the mpiexec that ships with Paraview

  I have a small test cluster and a 1Gbit switch.

  What is the recommended way to determine and record the network utilization for a given MPI run?

  I was hoping to gather such information over time and be in a proactive position to plan for network equipment update should I find that I start running into a situation where my network is becoming the performance bottleneck.

Cheers
