SPEC CPU2017 Platform Settings for ASUSTek Systems

Operating System Tuning Parameters

The OS 'cpupower' utility is used to change CPU power governors settings. Available settings are:
The 'tuned' provides a number of predefined profiles for typical use cases. The 'tuned-adm' command is used to change settings of the tuned daemon. The tuned-adm command can query current settings, list available profiles, recommend a tuning profile for the system, change profiles directly, or turn off tuning. Available profiles are:

Firmware / BIOS / Microcode Settings

Patrol Scrub:
Patrol scrubbing is a mechanism for the memory controller to periodically read all memory locations and write back corrected data. The time interval for scrubbing the entire memory is defaulted to 24-hour period. Values for this BIOS option can be: Enabled/Disabled. Current default is Enabled.
Intel VT for Directed I/O (VT-d):
Intel Virtualization Technology for Directed I/O (VT-d) by reporting the I/O device assignment to VMM through DMAR ACPI Tables. Values for this BIOS option can be: Enabled/Disabled. Current default is Enabled.
Enables Hyper Threading(Software Method to Enable Logical Processor threads. Values for this BIOS option can be: Enable/Disable. Current default is Enable.
Sub NUMA Clustering (SNC) is a feature for breaking up the LLC into disjoint clusters based on address range, with each cluster bound to a subset of the memory controllers in the system. It improves average latency to the LLC and is an important pre-requisite to enabling KTI prefetch and is a replacement for the Cluster-on-Die feature found in previous processors. SNC is only available on Ice Lake processors that have 12 or more LLC slices per die. Values for this BIOS option can be: Disable/Enable SNC2 (2-clusters). Current default is Disable.
SR-IOV Support:
In virtualization, single root input/output virtualization or SR-IOV is a specification that allows the isolation of the PCI Express resources for manageability and performance reasons. A single physical PCI Express can be shared on a virtual environment using the SR-IOV specification. If system has SR-IOV capable PCIe Devices, this option Enables or Disables Single Root IO Virtualization Support. Values for this BIOS option can be: Enabled/Disabled. Current default is Enabled.
This BIOS option allows for processor performance and power optmization. Available settings are:
Engine Boost:
ASUS individual feature with the power acceleration design to increase CPU over-all performance. Available settings are: Disabled(default), Normal, and Aggressive. Aggressive mode means it could improve CPU performance more aggressively than Normal mode, but comes with more power consumption and higher CPU temperature.
LLC dead line allc:
In the processor non-inclusive cache scheme, MLC evictions are filled into the LLC. When lines are evicted from the MLC, the core can flag them as “dead” (i.e., not likely to be read again). The LLC has the option to drop dead lines and not fill them in the LLC. This can help save space in the LLC and prevent the LLC from evicting useful data. Available settings are:
Fan mode:
To Select system Fan policy on BMC WebUI. Available settings are:
