actually, I typed wrong command in my earlier mail. My SCF calculation was indeed performed using 64 processors as:
aprun -N 8 -n 64 ./ph.x -npool 4 < ph.in > ph.out Next, I tried the image method for phonons using: aprun -N 8 -n 640 ./ph.x -nimage 10 -npool 4 < ph.in > ph.out Thanks, David _______________________________________________ Pw_forum mailing list Pw_forum at pwscf.org http://www.democritos.it/mailman/listinfo/pw_forum -------------- next part -------------- An HTML attachment was scrubbed...
