Non-Uniform Memory Access (NUMA)
Non-Uniform Memory Access (NUMA) is available on some Z series Workstations. NUMA can improve
memory bandwidth and latency for multi-process or multi-threaded applications or workloads.
Observed performance improvements depend on the operating system, customer workload, system
configuration, and the degree to which the applications used are designed to be NUMA-aware/
efficient.
NUMA requires that both processor sockets be populated. Installed memory should be balanced
between both processors for maximum performance.
NUMA is enabled if Memory Node Interleave is disabled in the system BIOS. To do this, press
F10
during startup to enter the Computer Setup (F10) Utility. Select
Advanced > Chipset/Memory
. Use
the arrow keys to set
Memory Node Interleave
to
Disable
. Press
F10
to exit the menu, then select
File > Save Changes
and
Exit
. NUMA is enabled when the system is restarted.
BIOS ROM
The BIOS ROM is a collection of machine language applications stored as firmware in ROM. It includes
functions such as Power on Self Test (POST), PCI device initialization, Plug and Play support, power
management, and the Computer Setup (F10) Utility.
