I'm using Charmm c34b1 on CentOS Linux 5.1 X86_64. My intel ifort version is 10.1 20080112.
Charmm was compiled by ifort with mpich-127/mpich2/openmpi/lammpi
I also compile a charmm with ifort and without any mpi.
Modify c34b1/test/cbenchtest/mbcodyn.inp
from
dyna cpt start nstep 1000 timestep 0.001 nbscale @s imscale @t -
to
dyna cpt start nstep 10000000 timestep 0.001 nbscale @s imscale @t -
With mpirun, all Charmmm program parallel on 8core within a node.
All of these program stop on step 2425 charmm output
