[OMPI users] Not getting mpi.mod file from openmpi build and install

OpenMPI version: 1.3.3 Platform: IBM P5 If I configure with just the --prefix option for where to install, and then run "make all install", I get an "mpi.mod" file in the "lib" directory of the prefix directory I specified. ALL GOOD! When I add compiler options to the configure script (e.g.

[OMPI users] Treatment of SIGHUP by mpirun

If a user connects to a cluster using SSH, starts an MPI program which contains an infinite loop, and then breaks the SSH connection, the processes running the MPI program continue to run on the compute nodes and they have to be killed manually. To investigate this, I found that if the user

Re: [OMPI users] How to debug Open MPI programs with gdb

You can run a X-windows server on your local machine and use the GUI for gdb, or use Eclipse Parallel Tools Platform (http://www.eclipse.org/ptp/) that has a debugger and turn on X-Forwarding in your Secure Shell client. -Original Message- From: users-boun...@open-mpi.org

Re: [OMPI users] How to debug Open MPI programs with gdb

I don't think the "debugger" option to mpirun will work with gdb - I believe it is intended to work with parallel debuggers such as Totalview. Looking at the code, I certainly can't see how gdb would work correctly with it. There is an mpirun option "-xterm" which will launch the xterm windows

[OMPI users] How to debug Open MPI programs with gdb

Hello, I tried to debug with command: "mpirun -debugger gdb -debug -np 4 my_program" Surely, it starts the debugger, but it doesn't start the debugging nor it loads any of the my_program threads into the debugger. If I start debugging manually ("file my_program", then "run"), I can start only
