Hi all,
According to FAQ 14 (How do I control how my processes are scheduled across nodes?) [http://www.open-mpi.org/faq/?category=running#mpirun-scheduling], it says that the default scheduling policy is by slot and not by node. I'm curious why the default is "by slot" since I am thinking of

I would start by improving the mentioned macro with specific support for each

because not all MPI implementations have
wrapper compilers -- so it's up to you to decide how portable you want
to be. The open source MPI's both have wrapper compilers by the same
names (mpicc et al.), but some of the vendor/MPP platform-specific
MPI's may not.
Good luck.

I'm very new to MPI and am trying to install it on to a Debian Etch

Then, I installed the following packages:
