Dear users, i compiled mpi version pwscf 4.1.2 on quad core. with ubuntu linux ./pw.x shows "Parallel Version (MPI)". In make.sys, DFLAGS contains -D__MPI and -D_PARA. I have mpirun installed.
may i know what is the complete mpirun command to initiate the calculation. when i run mpirun -np 2 ../../bin/pw.x<si.scf.in>si.scf.out i get error such as It seems that [at least] one of the processes that was started with mpirun did not invoke MPI_INIT before quitting (it is possible that more than one process did not invoke MPI_INIT -- mpirun was only notified of the first one, which was on node n0).
