Couple of things: 1. Check the configure cmd line you gave - OMPI thinks your local computer should have an openib support that isn't correct. 2. did you recompile your app on your local computer, using the version of OMPI built/installed there? On Nov 3, 2011, at 10:10 AM, amine mrabet

Re: [OMPI users] problem using mpirun over multiple nodes

Hi Jeff, Thanks to you, I figured the problem . As you suspected, it was iptables which was acting as firewalls in some machines. So, after I stopped the iptable, the MPI communication is going fine. Even I tried with 5 machines together and the communication is going allright. Thanks again,

ssh may be allowed but other random TCP ports may not. iptables is the typical firewall software that most Linux installations use; it may have been enabled by default. I'm a little doubtful that this is your problem, though, because you're apparently able to *launch* your application, which

I'm a afraid I don't know anything about OpenFoam, but it looks like it deliberately chose to abort due to some error (i.e., it then called MPI_ABORT to abort). I don't know what those stack traces mean; you will likely have better luck asking your question on the OpenFoam support list. Good

I verified that the preload functionality works on the trunk. It seems to be broken on the v1.3/v1.4 branches. The version of this code has changed significantly between the v1.3/v1.4 and the trunk/v1.5 versions. I filed a bug about this so it does not get lost:

Re: [OMPI users] Problem with mpirun -preload-binary option

I'm no expert on the preload-binary option - but I would suspect that is the case given your observations. That option was created to support checkpoint/restart, not for what you are attempting to do. Like I said, you -should- be able to use it for that purpose, but I expect you may hit a

Please see my earlier response. This proposed solution will work, but may be unstable as it (a) removes all of OMPI's internal variables, some of which are required; and (b) also removes all the variables that might be needed by your system. For example, envars directing the use of specific

I see. No, we don't copy your envars and ship them to remote nodes. Simple reason is that we don't know which ones we can safely move, and which would cause problems. However, we do provide a mechanism for you to tell us which envars to move. Just add: -x LD_LIBRARY_PATH to your mpirun cmd line

Re: [OMPI users] problem calling mpirun from script invoked with mpirun

Normally, one does simply set the ld_library_path in your environment to point to the right thing. Alternatively, you could configure OMPI with --enable-mpirun-prefix-by-default This tells OMPI to automatically add the prefix you configured the system with to your ld_library_path and path

Thanks for the quick reply. This leads me to another issue I have been having with openmpi as it relates to sge. The "tight integration" works where I do not have to give mpirun a hostfile when I use the scheduler, but it does not seem to be passing on my environment variables. Specifically

Re: [OMPI users] problem calling mpirun from script invoked with mpirun

I'm afraid we have never really supported this kind of nested invocations of mpirun. If it works with any version of OMPI, it is totally a fluke - it might work one time, and then fail the next. The problem is that we pass envars to the launched processes to control their behavior, and these
