Hello,
Intel MPI Benchmarks suite
(http://software.intel.com/en-us/articles/intel-mpi-benchmarks/) will probably
measure more things about your MPI environment than you'd ever need to know :)
NetPIPE (http://www.scl.ameslab.gov/netpipe/) also has an MPI version. It
measures point-to-point band
That's fine. In that case, you just compile it with your MPI
implementation and do something like this:
mpiexec -np 2 -H masterhostname,slavehostname ./osu_latency
There may be some all-to-all latency tools too. I don't really remember.

I'm not really familiar enough to know what you mean by "em slaves", but
for general testing of bandwidth and latency, I usually use the "OSU
Micro-benchmarks" (see http://mvapich.cse.ohio-state.edu/benchmarks/).
