Yes, the Intel Xeon processor 5500 series is supported. owever, the memory traffic is measured in the memory controller. Therefore it is not possible to measure it on a core basis, but only on a socket basis.
you can consult wikipedia articles on memory controller and QPI (Intel QuickPath Interconnect). The ratio QPI data traffic/ memory controller traffic is a metric to measure NUMA (Non-Uniform Memory Access)friendliness of applications. Memory bandwidth intensive applicationswork fasterif theyaccess mostly local memory (from local memory controller) and not remote memory from memory controller at a different processor/socket - which is slower. Data access to remote memory goes through QPI links.Applications accessing mostly local memory are NUMA-friendly; they donot utilize QPI links much. The metric you are asking about should be near 0 for NUMA-frienly applications. If the value tends to be closer to 1 or even greater, then you application is not particular NUMA-friendly (lots of data need to be transfered through QPI links compared to total memory controller traffic).
