It depends on what you are trying to do. Is your network physically
wired such that there is no direct link between nodes 1 and 2? (i.e.,
node 1 cannot directly send to node 2, such as via opening a socket
from node 1 to node 2's IP address)

the Open MPI mpif.h?
Also, there is a known problem tha

Hi,
I compiled a molecular dynamics program DLPOLY3.09 on an AMD64 cluster running
openmpi 1.2.4 with Portland group compilers.The program seems to run alright,

The error you are seeing may be caused by old connectivity
information in the session directory. You may want to make su
