Hi All,


I am attempting to run SU2 in parallel and am running into an issue.



Whenever I try to run a .cfg file (that I already have sucessfully run in serial using the ususal SU2_CFD command), I get an error that tells me that mpi doesn't recognize the SU2_CFD command. Here's what happens in my CLI:

aac1@aac1-VirtualBox:~/Desktop/0012_test$ mpirun -n 4 SU2_CFD config.cfg
--------------------------------------------------------------------------
mpirun was unable to find the specified executable file, and therefore
did not launch the job. This error was first reported for process
rank 0; it may have occurred for other processes as well.

NOTE: A common cause for this error is misspelling a mpirun command
line parameter option (remember that mpirun interprets the first
unrecognized command line token as the executable).

Node: aac1-VirtualBox
Executable: SU2_CFD
--------------------------------------------------------------------------
4 total processes failed to start

Has anyone else come across this issue and sucessfully solved it?


Cheers,
Moshe.

Hi Moshe,

There are two things that I can think that may be causing this problem:
1.) The path variables are set incorrectly, be sure they match what is output during the configuration process.

2.) The code wasn't compiled with parallel support.

These are my best guesses at the moment. Let us know if these were the issues, or have any more questions.
