Are you sure you are using mpich? The below error message about "mpirun" is not from mpich. -- Pavan On 09/21/2012 03:30 PM US Central Time, Elie M wrote:

Dear All, I have a problem. I am doing parallel computing using the QE package and while executing an executable ph.x , i get the error:

What might be the problem.... I am not sure if this might be causing it or not as I am not an expert in programming. The executable ph.x is found in a Package PHONONS which was a separate one from the Quantum espresso Pacakge. I unzipped it and compiled the executables which were put in the bin folder where all other executables are but they were shaded with different colours...I am not sure if this is causing the problem or not. Please help.
