* E8C is NUMA system on distributed memory and can have several nodes.

* Each node can have some memory (faster to access) and max 8 CPUs (cores)
|
|
* Node number is the same as chip-processor number
|
|
* Some nodes (CPUs) can be without memory
|
|
* LAPIC cluster number is the same as node number
