• On Dell’s 12th generation PowerEdge and later systems: single, all, dual, quad, 1, 2,
4, 6, 8, 10, 12, 14, 16, 18
Description
Controls the number of enabled cores in each processor. The default value is set to the
maximum number of cores per processor. The number of cores depends on the
processor. Reading the cpucore that is set to the highest value of number of cores
displays as all.
For example, if six-core CPU is installed, after setting to the highest value, 6, when you
read the cpucore, it displays as all.
Example:
A:>syscfg --cpucore=1
cpucore=1
Applicable Systems All PowerEdge systems.
ProcCoreSpeed*
Table 127. ProcCoreSpeed
Valid Arguments
• On systems prior to Dell’s 12th generation PowerEdge systems: NA
• On Dell’s 12th generation PowerEdge and later systems: Read-only
Description
Displays the clock speed of the processors.
Example:
A:>syscfg --ProcCoreSpeed
Applicable Systems Dell’s 12th generation PowerEdge and later systems.
ProcExecuteDisable/cpuxdsupport
Table 128. ProcExecuteDisable / cpuxdsupport
Valid Arguments
• On systems prior to Dell’s 12th generation PowerEdge systems: enable, disable
• On Dell’s 12th generation PowerEdge and later systems: Enabled, Disabled
Description
Enables or disables the Execute Disable Memory Protection Technology feature of the
CPU.
Example:
A:>syscfg --cpuxdsupport=enable
cpuxdsupport=enable
Applicable Systems All PowerEdge systems running on Intel processors.
ProcHwPrefetcher/hwprefetcher
Table 129. ProcHwPrefetcher / hwprefetcher
Valid Arguments
• On systems prior to Dell’s 12th generation PowerEdge systems: enable, disable
• On Dell’s 12th generation PowerEdge and later systems: Enabled, Disabled
Description
Enables or disables the hardware prefetcher. Processor preempts what data might be
needed next, when set to enable. When some data is found, it loads several steps in
advance.
Processor does not preempt, when set to disable.
This option can be replicated.
