Hello,
I'm having trouble running cases in parallel using mpirun. I installed OpenFOAM 4.1 on my Virtual Box (Ubuntu 12.04) using the following guide https://openfoamwiki.net/index.php/I...OAM-4.1/Ubuntu. The installation seems to work fine if I run cases normally, but when I try to run them in parallel, an error is displayed pointing at a missing config file. Code:
ubuntu@ubuntu-VirtualBox:~/OpenFOAM/ubuntu-4.1/run/tmp$ mpirun -np 4 rhoCentralFoam -parallel > log & [1] 9273 ubuntu@ubuntu-VirtualBox:~/OpenFOAM/ubuntu-4.1/run/tmp$ Cannot open configuration file /usr/share/openmpi/mpirun-wrapper-data.txt Error parsing data file mpirun: Not found Code:
ubuntu@ubuntu-VirtualBox:/opt$ ln -s /usr/bin/mpicc.openmpi OpenFOAM-4.1/bin/mpicc ln: failed to create symbolic link `OpenFOAM-4.1/bin/mpicc': File exists ubuntu@ubuntu-VirtualBox:/opt$ ln -s /usr/bin/mpirun.openmpi OpenFOAM-4.1/bin/mpirun ln: failed to create symbolic link `OpenFOAM-4.1/bin/mpirun': File exists Does anyone know what the purpose of "mpirun-wrapper-data.txt" or how I could modify "mpicc-wrapper-data.txt" in order to get it to work? Thank you in advance! |

Quick answer: The straight forward possible solution would be to reboot the virtual machine or at least log out and then log back inside Ubuntu, to ensure that everything that was installed with apt-get is now fully operational.
Then start a new terminal and make sure you run: Code:
