While I am not sure about the windows version, the 64-bit (intel) linux version
of G09 I use at my university will
certainly use all 8 cores I have on a shared memory node. I think you must
use the linda parallel version to run
jobs on multiple compute nodes, but I think the normal version requires nothing
special to run on shared cores
using the same memory space.
