[Octopus-users] how to build parallel version correctly ?

[Xavier Andrade]

Hi,

The easiest way to do it is to use the wrappers that mpi provides to the 
compiler, so instead of your compilers use mpicc and mpif90. So you 
should call configure like this (plus the other options you might need):

./configure --enable-mpi CC=mpicc FC=mpif90

Cheers,

Xavier
