Yes, that's where I compiled and installed the nightly snapshot to. (I did a make clean and recompile of the app, though I see that only hydra needed changing ) - I assumed that the mpich snapshot did include the updated hydra - if not, I should redo it with the fixed hydra.

I'll wipe everything and rebuild one more time just in case I messed up. Does it matter that I'm installing to a non standard location? Does it need to be on any system paths or have special privileges?

Non-standard locations are fine, as long as you use full paths to the executables. Just untar the nightly tarball and build from scratch. Technically you only need to get a new mpiexec, not the entire mpich, but it only takes a couple of minutes to build, so it's not a big deal either way. -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
