To Whom It May Concern: I'm trying to run Converge CFD by Converge Science using OpenMPI and I am getting the error:
bash: orted: command not found I've already read and executed the FAQ about adding OpenMPI to my PATH and LD_LIBRARY_PATH (https://www.open-mpi.org/faq/?category=running#adding-ompi-to-path). Here's my configuration: OS: CentOS 7.6.1810 x86_64 (it's a fresh install. I installed it last night.) OpenMPI version: 1.10.7 (that was the version that was available in the CentOS install repo) path to mpirun: /usr/lib64/openmpi/bin path to lib: /usr/lib64/openmpi/lib $ cat ~/.bashrc PATH=$PATH export PATH LD_LIBRARY_PATH=$LD_LIBRARY_PATH export LD_LIBRARY_PATH $ cat ~/.bash_profile PATH=$PATH export PATH LD_LIBRARY_PATH=$LD_LIBRARY_PATH export LD_LIBRARY_PATH $ cat ~/.profile PATH=$PATH export PATH LD_LIBRARY_PATH=$LD_LIBRARY_PATH export LD_LIBRARY_PATH $ cat /etc/profile ... PATH=$PATH:...:/usr/lib64/openmpi/bin export PATH LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/openmpi/lib export LD_LIBRARY_PATH SI8_premix_PFI_SAGE$ cat node003_16_node004_16.txt node003 node003 node003 node003 node003 node003 node003 node003 node003 node003 node003 node003 node003 node003 node003 node003 node004 node004 node004 node004 node004 node004 node004 node004 node004 node004 node004 node004 node004 node004 node004 node004 command that I am trying to run that results in the error: SI8_premix_PFI_SAGE$ time -p mpirun -hostfile node003_16_node004_16.txt /opt/converge_2.4.0/l_x86_64/bin/converge...ompi 2>&1 | tee run.log However, if I run where I explicitly give the absolute path to the mpirun, then it works: SI8_premix_PFI_SAGE$ time -p /usr/lib64/openmpi/bin/mpirun -hostfile node003_16_node004_16.txt /opt/converge_2.4.0/l_x86_64/bin/converge...ompi 2>&1 | tee run.log I also tried exporting the PATH and LD_LIBRARY_PATH to the slave node and that didn't seem to work (results in the same error): SI8_premix_PFI_SAGE$ time -p mpirun -x PATH -x LD_LIBRARY_PATH -hostfile node003_16_node004_16.txt /opt/converge_2.4.0/l_x86_64/bin/converge...ompi 2>&1 | tee run.log I think that I'm using bash shell (I think that's the default for CentOS users), but to be sure, I created the .profile anyways. passwordless ssh has been properly configured, so that's not an issue (and I've tested that permutatively). The two nodes can ping each other, back and forth, also permutatively as well. I'm at a loss as to why I need to specify the absolute path to mpirun despite having everything else set up and to me, it looks like that I've set everything else up correctly. Your help is greatly appreciated. Thank you. Sincerely, Ewen Chan
