Hi,
I have entered the IP address of the system in the hosts
file (twice the IP for two CPU's) .I don't know about this mca
parameter. Can you please tell me about this or any reference
material for this parameter? Actually the input file is to perform
minimization of the protein using CHARMM program. It is not giving
any error message as which rank stopped. The output shows that the
first charmm stops and the job runs on the other which is fully
completed.
When I tried to check for the CPU's it actually encounts, I gave the
command in charmm and it replied only one CPU. Is there anything
wrong in the way of adding CPU's?
Thanks for help

Could you pass along what is in your hosts file? Did you set any mca
params in the default mca parameter file, or in your environ?
I note that you redirected stdin. Which rank is running and which is
stopped? How big is your input file? I am not familiar with your
program - are both ranks expecting to get stdin, or only rank=0?
Thanks
Ralph

Hi All,
I am a new user of Open MPI. I have installed open mpi-1.3
on a RedHat Linux-5 ver system with F77 set as gfortran compiler. I
tested the programs in examples and all ran. When I tried the CHARMM
program with mpirun (2 CPU's) the job runs on single processor and
it is stopped in the other. Actually I clarified that the error is
not with CHARMM. Is there any error in my MPI procedure? I gave the
job run as
mpirun -hostfile hosts -np 2 charmm < *.inp
Thanks for any help.
Varsha.
