Has anyone in the users list conducted any kind of analysis about using a head
node as a compute node in a distributed system?
Does it effect resources, or simply chance performance in any way?
Thanks!

Hello,
My understanding is Open MPI can utilize shared and/or distributed memory
architecture (parallel programming model). OpenMP is soley for shared memory
systems.
I believe Open MPI incorporates OpenMP from some of the other archives I
glanced at.
Is this a true statement? If so, is there

Hello all,
First time on here. Two questions.
1. I know OpenMPI supports ethernet, but where does it clearly state that?- I
see on the FAQ on the web page there is a whole list of network interconnect,
but how do I relate that to Ethernet network etc.?
2. Does OpenMPI work with PCIe and PCIe swit
