Hello, I'm interested in using PMI from mpich programs. Can someone tell me what the status of PMI is? Is it usable or is it in an experimental state? Do I need to build mpich with any special flags to take advantage of it? I have a program developed on a Cray that I would like to port to other machines, but I get an error when compiling (using mpicc) about not finding pmi.h. Kevin Olson
