Re: [QE-users] The pencil decomposition option
Dear Professor Paulo Thanks for your response. -pd .true. is a command-line option of the code, not of mpirun, so: mpirun [options] pw.x -pd .true. [other options] >>> I have gathered that I misplaced the option. It works fine now.

Re: [QE-users] The pencil decomposition option
Dear Lorenzo, Thanks for your quick response. i tried this: mpirun pw.x -pd.true. < 1Tppp-mos2.scfeq.in > scfeq.out and it worked perfectly fine.
