Each core is actually a processor, and that's the way QE reports it. You are actually running on only one core. > I am using the script that come inside the example tar downloaded from > QE site. There are many scripts in the examples tarball. Please refer to the mpiexec documentation. If you are referreing to environment_variables, maybe you haven't noticed that the PARA_PREFIX variable is defined twice, one after each other, if you have changed the first, than your modification is overwritten immediately afterwards (yes, it is a error of the script). 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/
