HP says that what they call “NUMA split mode” should be disabled in the BIOS of the Z800 workstation when running Linux. They are reasoning that Linux kernels do not support this feature and even might not boot if it´s enabled.
Since it apparently was years ago since they made this statement, I´m wondering if I should still leave this feature disabled or not. More recent kernels might support it, and it´s supposed to improve performance.
Could someone explain what this feature actually is or does, and if CentOS kernels support it?
“Didn’t work” is an error.
