Dear pwscf users, I am trying to run pwscf in parallel on a core2duo cluster. It seems to compile fine (I am using mpiifort), and I am able to send a parallel calculation on two cores (therefore two processes but only one processor). Unfortunately, when I want to use more cores, and therefore more than one processor, for example:
> mpirun -np 4 pw.x -npool 1 < scf.inp this runs four processes but only on two cores, with the following error at the beginning of the output: > You can't run mpdboot on ['compute-0-5'] version of python must be > >= 2.4, current [''] I have been said that this error could be corrected by adding -r ssh, with: > mpirun -r ssh -np 4 pw.x -npool 1 < scf.inp but actually, this does not make any difference. Would you have any idea on the origin of this error and how to correct it?
