Dear Sir/Madam,
I'm running OpenMPI 1.4.2 version. The operation system is Ubuntu 9.10
with kernel version 2.6.31-14.
$ mpirun -np 1 -cpus-per-proc 1 -bind-to-core a.out
* This works fine on single core P4 machine.*
$ mpirun -np 1 -bind-to-core a.out
*This also
Which version of OMPI are you running on and the OS version?
Can you try and replace the rankfile specification with --bind-to-core
and tell me if that works any better?

I launched my mpi app using,
$ mpirun -np 1 -rf rankfile
