Hi, does anyone have experience with AMD's 12-core Magny-Cours processors? With 48 cores on a node it is essential that the processes are properly pinned to the cores for optimum performance. Numactl can do this, but at the moment I do not get good performance with 4.5.1 and threads, which still seem to be migrating around.
