Write Privilege Server Control License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable BIOS.ProcSettings.LogicalProc (Read or Write) Description Each processor core supports up to two logical processors. When set to Enabled, the BIOS reports all logical processors. When set to Disabled, the BIOS only reports one logical processor per core. Generally, higher processor count results in increased performance for most multi-threaded workloads and the recommendation is to keep this enabled. However, there are some floating point/scientific workloads, including HPC workloads, where disabling this feature may result in higher performance. Processor must support HyperThreading. Legal Values ● Enabled ● Disabled Default Value Not Applicable Write Privilege Server Control License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable BIOS.ProcSettings.MadtCoreEnumeration (Read or Write) Description This field determines how BIOS enumerates processor cores in the ACPI MADT table. When set to Round Robin, Processor cores are enumerated in a Round Robin order to evenly distribute interrupt controllers for the OS across all Sockets and Dies. When set to Linear, Processor cores are enumerated across all Dies within a Socket before enumerating additional Sockets for a linear distribution of interrupt controllers for the OS. Only visible on systems with AMD processors. Legal Values ● RoundRobin ● Linear Default Value Not Applicable Write Privilege Server Control License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable BIOS.ProcSettings.NumaDistanceEnum (Read or Write) Description This field determines how BIOS enumerate NUMA nodes distance in ACPI SLIT tables. When set to physical, NUMA node distance will enumerated by physical architecture. When set to logical, the level of NUMA node distance will simplified by logical distance for better OS capability.
