There are multiple answers possible here. One is related to the over-
subscription of your cluster, but I expect that there are at least 4
cores per node if you want to use the slots=4 option. The real
question is what is the communication pattern in this benchmark ? and
how this match the d

There are a huge number of MPI profiling tools out there. My
preference will be something small, fast and where the output is in
human readable text format (and not fancy graphics). The tools I'm
talking about is called mpiP (http://mpip.sourceforge.net/). It's not

Hi Warner,
how many nodes does your cluster have? I assume it is using only one
process per node by default. With slots=4 yo
Hi,
What is the best way of getting statistics on the size of MPI messages
being sent/received by my OpenMPI-using application? I'm guessing MPE is
one route but is there anything built into OpenMPI that will give me
this specific statistic?
Thanks,

Curious performance when using OpenMPI 1.2 to run Amber 9 on my
Xserve Xeon 5100 cluster. Each cluster node is a dual socket, dual-
core system. The cluster is also running with Myrinet 2000 with MX.
I'm just running some tests with one of Amber's benchmarks.
It seems that my hostfiles effec
