between NUMA nodes (e.g., QPI/UPI)
NODE = Connection traversing PCIe as well as the interconnect between
PCIe Host Bridges within a NUMA node
PHB = Connection traversing PCIe as well as a PCIe Host Bridge
(typically the CPU)
PXB = Connection traversing multiple PCIe bridges (without traversing
the PCIe Host Bridge)
PIX = Connection traversing at most a single PCIe bridge
