Re: [OMPI users] [EXTERNAL] Using Open MPI with multiple versions of GCC and G++
Can you try setting the environment variable OMPI_CXX= Then run: mpicxx -v and see what version it says its running. You may have to be careful mixing the versions too far apart.

Re: [OMPI users] PROBLEM WITH MPIRUN
Hi, This isn't usually an error - you get this by using conventional Fortran exit methods. The Fortran stop means the program hit the exit statements in the code. I have only had this with PGI. -- Si Hammond Research Fellow & Knowledge Transfer Associate Performance Computing & Visualisation Department of Computer Science University of Warwick, UK, CV4 7AL -- On 29 November 2010 04:56, Tushar Andriyas wrote: > Hi there, > I have posted before about the problems that I am facing with mpirun.

[OMPI users] OpenMPI and Port Range
Hi all, Is there anyway to specify the ports that OpenMPI can use? I'm using a TCP/IP network in a closed environment, only certain ports can be used. Thanks, Si Hammond University of Warwick

We are planning on using OpenMPI as the basis for running MPI jobs across a series of workstations overnight. The workstations are locked down so that only a small number of ports are available for use. If we try to use anything else its disaster. Unfortunately this is really an organizational policy above anything else and its very difficult to get it to change.

Sounds very drastic, thanks for the advice. I'll give it a go. Do you think it might be easy to add this to the source code at sometime though?

Re: [OMPI users] Problems with program-execution with OpenMPI: Orted: command not found
Hi, Have you checked the .bashrc or /etc/bash.bashrc file on the machine. We have seen this problem before on both Debian and Ubuntu systems. If you find the following line: # If not running interactively, don't do anything [ -z "$PS1" ] && return It means that the remainder of the file is not processed (which may include setting up your PATH/LD_LIBRARY_PATH) if you are connecting via a non-interactive login. Since this command only works for non-interactive logins the user falsely gets the idea that the PATH/LD_LIBRARY_PATH when they log in over SSH. We commented this line out and it worked for us, so just an idea.

Re: [OMPI users] where is mpif.h ?
Yes, it should be there. Have you configured OpenMPI with Fortran during the build?

Re: [OMPI users] mpirun (signal 15 Termination)
Do you get anything else in the output? We sometimes get this but it means the execution has proceeded sucessfully.
