I would also suspect there is some optimization occurring in the HP test case,
either via compiler or tuning, as that much speed difference isn't something
commonly observed.

Thank you very much guys. Now a more serious issue:
I am using mpi with laamps (a molecular dynamics package) on a single Rack
Dell server Poweredge R810
(4 eight-core processors, 128 Gb RAM memory).
I am now potentially interested into buying the Intel MPI 4.1 libraries,
and I am trying them by e
oops...
Sorry about that.

This looks like you're trying to execute an MPICH2-build MPI executable, not
Open MPI.

The reason is that you aren't actually running Open MPI - those error messages
are coming from MPICH. Check your path and ensure you put the OMPI install
location first, or use the absolute path to the OMPI mpirun

Hello!
I have built open mpi 1.6 with Intel compilers (2013 versions). Compilation
was smooth, however even when I try to execute
the simple program hello.c:
mpirun -np 4 ./hello_c.x
