gethostbyname error in REDHAT

Asked by transoft in Linux Setup

Hi

I have a quadricore system with REDHAT Enterprise version 5 64 bit.
I have MPICH on the system and need to run a parallel application with mpirun.

When I run mpirun by specifying the number of processors as 1,2,3 or 4 processors
I get the error message

p0_24205: p4_error: Could not gethostbyname for host NASSAU; may be invalid name
: 61

It seems that mpirun is not able to find the hostname. Here my hostname is NASSAU
Earlier the hostname was LINUX. I changed it later to NASSAU.

Do I need to change any other parameters. Is the system still recognising LINUX as the hostname ? I have also enabled rsh service as MPICH uses rsh.

Thanks for your help
