Maybe the `mpiexec` isn't found and a submitted script could help: #!/bin/sh . ~/.profile which mpiexec # remove this line when it's working mpiexec ... (Replace ~/.profile with ~/.bash_profile or ~/.bash_login in case you use these. In case `mpiexec` is available even without these: is there something like /etc/profile which needs to be sourced?) -- Reuti > Is there any other scheduling command to schedule task? > > Thank you in advance. > > Best Regards, > Shi Wei > > --- Original Message --- > > From: "Ralph Castain" <r...@open-mpi.org> > Sent: 27 August 2013 11:33 > To: "Open MPI Users" <us...@open-mpi.org> > Subject: Re: [OMPI users] Unable to schedule an MPI tasks > > Perhaps I don't understand, but mpirun has no problem being executed using > the "at" command.
