[mpich-discuss] Unable to run program parallely on cluster... Its running properly on single machine...

[Albert Spade]

Hi everybody,

I am using mpich2-1.4.1p1 and mpiexec from hydra-1.5b1
I have a cluster of 5 machines.
When I am trying to run the program for parallel fast fourier transform on
single machine it runs correctly but on a cluster it gives error.
Can you please tell me why its happening.

Thanks.

Here is my sample output:
