Hello dear QE users, I have solved the QE + openmpi parallel problem, The reason for the problem as follows, though I install openmpi and QE, I did not add the openmpi bin to the bashrc, so in fact I compile the QE without openmpi, as show in the ouput file ,it is still a serial version. Now, I recompile the QE after openmpi is OK. It is Parallel version (MPI). Thank you for your attention! Best wishes! JWY
