Dear Camps, let's have a look at all the output, not just the last line:

There must be an error in one of these lines, or in the way you combine them together. I cannot say which, because I don't use lam and I don't have access to the script you've used. > export PARA_PREFIX="mpiexec -n 4" > export PARA_POSTFIX="-npool 1" > PWgui="/software/PWgui-4.1" Double-check the script, maybe you only have to replace -n with -np. best regards. -- Lorenzo Paulatto SISSA & DEMOCRITOS (Trieste) phone: +39 040 3787 511 skype: paulatz www: http://people.sissa.it/~paulatto/ *** save italian brains *** http://saveitalianbrains.wordpress.com/
