Why not generate an ifort version with a prefix of _intel
And the gfortran version with a prefix of _gcc
?
That's what I do and then use mpi-selector to switch between versions as
required.

Is it correct to assume that, when one is configuring openmpi v1.3.2 and if
one leaves out the
--with-openib=/dir
from the ./configure command line, that InfiniBand support will NOT be built
into openmpi v1.3.2? Then, if an Ethernet network is present that connects
all the nodes, openmpi will us
sed nor have I asked about the use of
--enable-static for their 1.3.2 configurations.
I will have to follow-up on that.

Do I install them all on my compute nodes or just a subset?
Thanks for the help.

Noam, Gus and List,
Did you statically link your openmpi when you built it? If you did (the
default is NOT to do this) then that could explain the discrepancy.

This is what I get
[root@master ~]# ompi_info | grep openib
MCA btl: openib (MCA v2.0, API v2.0, Component v1.3.2)

For the app I am using, ORCA (a Quantum Chemistry program), when it was
compiled using openMPI 1.2.8 and run under 1.2.8 with the following in
the openmpi-mca-params.conf file:
btl=self,openib
the app ran fine with no traffic over my Ethernet network and all
traffic over my Infiniband network.

Never mind. I figured it out for myself.

I need to use openMPI in a mode where the input and output data reside
on one node of my cluster while all the other nodes are just used for
computation and send data to/from the head node.
All I can find in the documentation are cases showing how to use openMPI
for cases where input and output da
23 matches
