[mpich-discuss] HPC cluster network utilisation monitoring tool ?

[Nicholas Yue]

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
