[gmx-users] mpi mdrun

[jayant james]

Hi!
Thanks for your reply. So I suppose I need to have a hostfile in my
directory and call it during the mpirun command.  I have one clarification,
since I am using a quad core how am I to list the processors on the host
file? would it need to open a file name \d hostfile and have a list for
example like some thing below?
processor1
processor 2
processor 3
processor 4

or is getting to the hostfile an automated process (i.e.,) results from
executing a program?
I just put a search for host file and saw a folder by that name in the
directory below
~/software/open-mpi-1.2.8/orte/mca/rds/hostfile
Thanks
JJ
