Setting Numa Group Size Optimization; Enabling Or Disabling Intel Performance Monitoring Support; Configuring Uncore Frequency Scaling - HPE ProLiant Gen10 User Manual

Setting NUMA Group Size Optimization

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
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Power and Performance Options > NUMA Group Size Optimization.
2. 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.
3. Save your setting.

Enabling or disabling Intel Performance Monitoring Support

Intel processors include performance counters that software can use to measure DRAM performance
(including NVDIMM-N performance). This option is a monitoring tool, and does not impact performance.
For example, the Intel Performance Counter Monitor (PCM) tools can report per-channel bandwidth.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Power and Performance Options > Intel Performance Monitoring Support.
2. Select a setting.
• Enabled
• Disabled
3. Save your setting.

Configuring Uncore Frequency Scaling

Use the Uncore Frequency Scaling option to control the frequency scaling of the processor's internal
busses.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Power and Performance Options > Uncore Frequency Scaling.
2. Select a setting.
