Hello, mpif90, mpicc and mpirun are all in desired folder
/usr/lib/mvapich-intel-x86_64/bin/.
User run task by typing in command line "mpirun -np 32 -maxtime 1000 -queue
regular sander.MPI -sander_options". This is instruction for /usr/bin/mpirun
script that just add task to queue. When processors are available this task
is run by genuine mpirun.
I'm not shure that problem is related with this "sophisticated" procedure
because it works before upgrades..
Thanks,
