NUMA Group Size Optimization
Use this option to configure how the System BIOS reports the size of a NUMA node (number of logical processors), which assists the Operating System in grouping processors for application use (referred to as Kgroups).
The default setting of Clustered provides better performance due to optimizing the resulting groups along NUMA boundaries.
However, some applications might not be optimized to take advantage of processors spanning multiple groups.
In such cases, selecting the Flat option might be necessary in order for those applications to utilize more logical processors.
