Dear Carsten Kutzner
First, I am very thankful to you and highly appreciate your help. According to
your guideness I given the path for mdrun_mpi and the command run successfully.
But now the problem is the simulation run for some time and the killed and give
the error which is :
p10_522: p4_error: Timeout in establishing connection to remote process: 0
p8_468: p4_error: Timeout in establishing connection to remote process: 0
p9_495: p4_error: Timeout in establishing connection to remote process: 0
p0_32740: p4_error: net_recv read: probable EOF on socket: 1
Killed by signal 2.
Killed by signal 2.
p4_359: p4_error: net_recv read: probable EOF on socket: 1

I dont know how to solve this problem. Any help in this respect will be by
highly appreciated by our research group.
