[OMPI users] OpenMPI 2.x + PGI + Mellanox OFED

Matt Thompson reported an issue over the summer that prevented one from using OpenMPI when built with the PGI compilers and Mellanox OFED (At least the 3.x series). The thread is here https://www.mail-archive.com/users@lists.open-mpi.org/msg29698.html. Information about how PGI is reacting with

[OMPI users] Memory management and data structures with OpenMPI.

Greetings, I need help understanding how I can better manage memory in my code. sizeof(x)=8 (file main.cpp) and this is always equal to the number of processes spawned. How do I ensure that sizeof(x) = 1 and that it is a 1D array of size num (from main.cpp). I would like to import utils.h as

Re: [OMPI users] Hello world Runtime error: Primary job terminated normally, but 1 process returned a non-zero exit code.

What Gilles suggested is probably the right answer. There's a Linux executable named "test" already (e.g., /usr/bin/test) that is not an MPI application. When you didn't specify a path, mpirun probably found and ran that one instead. > On May 22, 2017, at 9:58 AM, Gilles Gouaillardet > wrot

[OMPI users] Hello world Runtime error: Primary job terminated normally, but 1 process returned a non-zero exit code.

Hello All, I'm able to successfully compile my code when I execute the make command. However, when I run the code as: mpirun -np 4 test The error generated is: --- Primary job terminated normally, but 1 process returned a non-zero exit code..
