Enhanced Processor Core Disable (Intel Core Select)
NOTE: This option is available on some G7 and Gen8 servers with Intel processors.
The Enhanced Processor Core Disable option allows you to specify the number of cores to enable
per processor socket, in multiples of 2. Unused cores are disabled.
Depending on the applications used, controlling the number of cores to enable has the following
benefits:
•
Reduces processor power usage and improves overall performance
•
Improves overall performance for applications that benefit from higher performance cores
rather than from additional processing cores
•
Addresses issues with software licensed on a per-core basis. Software licensing issues with
enabling or disabling processor core count may exist. For more information, see your software
licensing agreement and user documentation.
After reading the window with additional information about this option, press any key to display
the box in which to enter the number of cores to enable per processor socket.
Options include:
•
All (default)
•
User-defined entry, in multiples of 2
