I am trying to use mpich2 1.4.1 alongside Quantum Espresso 5.3. I have been using Windows 7 Enterprise version on Intel Xeon processor. 

I have followed instructions given in the following link to install mpich2 for windows 7:

However, when I am trying to execute QE in parallel formation I am getting the following error:

I use the following line to run QE using mpich2:

mpiexec -localonly -np 8 pw <abc.scf.inp>

I don't know what's wrong here. 

I can run single execution using QE. However, I have not been able to run parallel execution. What should I do? 

Any help will be highly appreciated.

Thanks
