Hi Brad/others
Sorry for waking this very stale thread, but I am researching the
prospects of CellBE based supercomputing and I found this old email a
promising lead.
My question is: what was the reason for choosing to mix an x86 based
AMD cores and PPC 970 based Cell? Was the Cell based computer

Ahh...sorry for the confusion. By "unmodified", I meant
Brad just curious.
Did you tweak any other values for starting and running a job on such
a large system? You say unmodified, but OpenMPI lets you tweak many
values at runtime.
I would be curious to expand what I know from what you discovered.

Greetings Open MPI users; we thought you'd be interested in the
following announcement...
A new supercomputer, powered by Open MPI, has broken the petaflop
barrier to become the world's fastest supercomputer. The
"Roadrunner" system was jointly developed by Los Alamos National
Laboratories and IB
