This seems to imply that *some* OpenFabrics service starte
Gustavo,
I will definitely try to compile OpenMPI myself and see if the problem
persist
Regarding your note on homogeneous nodes; I tried to do that as much as
possible.
But I had no control over two nodes and each of them had different setup.
As Jeff suggested, using .bashrc seems to solve the is
Jeff,
My computer doesn't have such a service. and I think that's the correct
name for Fedora
Also, what bugs me is that it used to work with no warnings before
restarting my computer.
I will try to recompile openMPI myself (as opposed to installing it using
yum) and see what happens

Hi Tohiko
If you compiled Open MPI in a computer with IB hardware,
then copied the installation tree to another machine,
or if you installed from an RPM or other package generated in a
machine with IB, your OpenMPI will have IB enabled, I think, even if the
machine where it is running does not
It is possible to have the OpenFabrics drivers loaded in your kernel, even if
you have no OpenFabrics-based devices in your hardware.
You probably just want to unload those drivers, and then Open MPI should not
try to use OpenFabrics. Sometimes distros have init scripts that load the
OpenFabri
Do you get any interfaces shown when you run "ibstat" on any of the
nodes your job is spawned on?

Hi Tohiko
OpenFabrics network a.k.a. Infiniband a.k.a. IB.
To check if the compute nodes have IB interfaces, try:
lspci [and search the output for Infinband]
To see if the IB interface is configured try:
ifconfig -a [and search the output for ib0, ib1, or similar]
To check if the OFED module
Sorry for the noob question, but how do I check my network type and if OFED

Thank you,

Do you have an OpenFabrics-based network? (e.g., InfiniBand or iWarp)
If so, this error message usually means that OFED is either installed
incorrectly, or is not running properly (e.g., its services didn't get started
properly upon boot).
If you don't have an OpenFabrics-based network, then i
Greetings,
Until today I was running my openmpi applications with no errors/warnings
Today I restarted my computer (possibly after an automatic openmpi update)
and got these warnings when
