Dear gmx users,
I have installed the parallel version 4.0.7 of gromacs on one of the nodes
of my cluster. Here is the steps I've done through root:
first, the normal installation:
then issued commands below for the mpi build:
I dont see any errors and everything seems to install fine.
I then switch to a normal user to do my work and then after issuing
the grompp_md command as usual, I entered the command below:
mpirun -np 8 mdrun_mpi -s *.tpr -o *.tpr -c *_after_md -v >& output.mdrun_md
however, output.mdrun_md gives:
mpirun was unable to launch the specified application as it could not
find an executable:
while attempting to start process rank 0.
Was the installation procedure incorrect? Or do I need to go through a
separate installation for the mdrun_mpi executable? Please guide me on what
-------------- next part --------------
