Interleaving Mode
In Interleaving mode the cache lines will be distributed over different memory
boards (via the Mboxes) for better performance.
Interleaving Types:
–
2-way interleaving (also called "Intra Socket Interleaving")
This type requires 2 memory boards per CPU and is possible with 2, 3 or 4
CPUs. The data are distributed over the Mboxes of each CPU (see
figure 9
on page 29
). Therefore, this type is called "Intra Socket Interleaving".
–
4-way interleaving mode (also called "Inter Socket Interleaving")
This type requires 2 memory boards per CPU and is possible with 2 or 4
CPUs. The data are distributed over the Mboxes of two CPUs (see
figure 10
on page 30
). Therefore, this type is called "Inter Socket Interleaving".
–
8-way interleaving mode (also called "Inter Socket Interleaving")
This type is only possible with 4 CPUs and requires 2 memory boards per
CPU. The data are distributed over the Mboxes of four CPUs (see
figure 11
on page 31
). Therefore, this type is called "Inter Socket Interleaving".
