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

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 On Wed, Feb

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

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

Mm... This is really strange I don't have that service and there is no ib* output in 'ifconfig -a' or 'Infinband' in 'lspci' Which makes me believe that I don't have such a network. I also checked on an identical computer on the same network with the same results. What's strange is that these

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

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
