NUMA: Non-Uniform Memory Architecture
In a NUMA system, processors, memory, and I/O are grouped together into nodes/cells.
The memory in NUMA systems is physically distributed but logically shared.
Under NUMA, a processor can access its own local memory faster than non-local memory
Each of the ‘cells’ may be viewed as an SMP [symmetric multi-processor]
(Cell 1) (Cell 2) CPU 1 --- Inter-connect --- CPU 2 | | RAM 1 RAM 2
Inter-Connect
- AMD: Hyper Transport (HT) interconnect
- Intel: Quick Path Interconnect (QPI)
應用: Super Computers (解決多 Core 到 Memory 的 bottleneck)
