MPI error message

[nemer abosamha]

Hello Everyone, 

I am trying to run FDS experiment for two meshes on two processors in Linux, but i keep receiving this error message :

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).

Here is my command : mpirun -np 2 fds_mpi ceiling_vent.fds

, any suggestion ?

We stopped distributing both an mpi version and a non-mpi version some time ago. If you are running a recent release (which we of course encourage that you do), there is only fds and not both fds and  fds_mpi. This is documented in the User's Guide.

You should always verify which executable to are running:

$ which fds
~/FDS/FDS6/bin/fds

If your computer can't find it, add the FDS install directory to your path or set an alias or just provide the full path name.
