Use the NUMA Group Size Optimization option to configure how the system ROM reports the number of logical processors in a NUMA (Non-Uniform Memory Access) node. The resulting information helps the operating system group processors for application use.
Procedure
From the
System Utilities screen, select
System Configuration > BIOS/Platform Configuration (RBSU) > Power and Performance Options > NUMA Group Size Optimization.
Select a setting.
Clustered—Optimizes groups along NUMA boundaries, providing better performance.
Flat—Enables applications that are not optimized to take advantage of processors spanning multiple groups to utilize more logical processors.
