Hi, David and Anton,
Thanks a lot for your email messages which are very helpful to me. According to your good suggestion, I do several tests on my system:
1. run "mpirun" on single processor, the EM successfully passes with the same em.mdp.
2. run "mpirun" on 4 processors also can pass when add "define -DPOSRES"
3. after energy minimization, the md also passes.
