Benchmarking MPI Collectives

[c***@gmail.com]

We know that if we have to benchmark point to point communications of
any MPI library particularly Send and Recv functions, we use the
"PingPong" program in which two processes send and receive data from
each other.

I want to ask that what are the standard benchmarks for Collective
Communications such as Allgather, Gather, etc... are there any
standard benchmarks??

I don't know if it is justified to call it a »standard benchmark«.
However, Intel® MPI Benchmarks [1] also cover collective
communications.
