[Pw_forum] paralel calculations

[Dariusz Chrobak]

Dear PWSCF users,

I would like to start 4 processes on  two (one-processor) computers.
I'm using MPICH-1.2.5.2 MPI implementation with the machines.LINUX file:

kometk.ifichm.us.edu.pl
kometk.ifichm.us.edu.pl
zgredek.ifichm.us.edu.p
zgredek.ifichm.us.edu.pl

The command:

mpirun -np4 ../bin/pw.x -npool 2 < nmgs.in > nmgs.out

starts my calculation and create the following PI#### file:

kometk.ifichm.us.edu.pl  0  ../pw.x
kometk.ifichm.us.edu.pl  1  ../pw.x
zgredek.ifichm.us.edu.pl  1  ../pw.x
zgredek.ifichm.us.edu.pl  1  ../pw.x

Could you tell me are the above numbers correct? What mean these numbers?

Best regards
Darek Chrobak
