Like Titan and OIC Phase 5, Metis uses the AMD interlagos chip. With these cpu there is only one floating point per 2 cores. From the perspective of most scientific computing this means a the number of cores is halved. If you don't correctly map your processes onto the nodes you'll waste significant computing time.
