ccNUMA support
HP's cell-based platforms are ccNUMA (cache coherent, Non-Uniform Memory Access)
capable, i.e. latency and bandwidth of a same-cell memory access is better than accessing
memory on a different cell. For ccNUMA platforms, 11.23PI is ccNUMA-aware. This maintains
good behavior for applications that are not ccNUMA-aware and gives applications, that are
ccNUMA-aware the ability to control their memory placement as well as processor placement.
This is a core feature of 11.23PI.
