[pankaj sejwal <pankajsejwal2@xxxxxxxxx>]

I am new to mpi programming ,I need lil help...
I have used eclipse but here eclipse run configuration I have to set to run MPI programs...
I did set all configurations properly using guide on website of eclipse but when I run it it gives me the following error:

--------------------------------------------------------------------------
mpirun was unable to launch the specified application as it could not access
or execute an executable:

Executable: /home/joker/workspace1/pi
Node: ubuntu

while attempting to start process rank 0.

This works fine when I run it on terminal using mpicc... but here its problem. I am giving ./a.out as application path.Am I doing it wrong,if it's so please suggest me!!

thank you!
