[mvapich-discuss] job metrics

[Hari Subramoni]

Hello Walid,

There are several profilers like mpiP, IPM, TAU and HPCToolkit that allows
folks to characterize the job and workload in terms of number of / time
spent in MPI calls with relatively low overheads. The amount of overhead
cause and the level and kind of detail provided differs from profiler to
profiler.

Thx,
Hari.
