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.
