	I have recently converted a pvm program to MPI, but I have not
found a parallel to the machine speed information that is available from
PVM.  I run my application on networks of workstations, and I need
to decompose the problem to fit the relative performance of different
machines.  Is there an MPI call, or MPI extension, that will allow me
to (1) encode information about the machines and (2) learn the names
of all the machines, and their encoded information, by the managing (0)
machine?

	Currently I am using the MPICH/p4 implementation.  Is this
information more readily available in the LAM implementation?
