[gmx-users] Unable to fire-up the parallel processes on cluster

[Venkat Reddy]

Dear Gromacs users,
I am trying to invoke a parallel job on three nodes (i101,i102,i103) using
the command as given in gromacs manual
mpirun -p i101,i102,i103 8 mdrun_mpi -v -s npt_100.tpr -deffnm npt_100

but its giving me an error like:
mpirun was unable to launch the specified application as it could not find
an executable:

Executable: -p

Please help me in this regard


With Best Wishes
