| |
Hi,
I have a SuperMicro X8DTH-6F motherboard with 2 cpus it has NUMA options in the BIOS; what parameters/should I be using for the NUMA options in the kernel?
| | [*] Numa Memory Allocation and Scheduler Support | | | | [ ] Old style AMD Opteron NUMA detection | | | | [*] ACPI NUMA detection | | | | [ ] NUMA emulation | | | | (6) Maximum NUMA Nodes (as a power of 2) | |
Specifically, the maximum number of NUMA nodes? Will this help to increase performance of large memory allocations/is there any downside to enabling this feature?
Justin.
