Subject: 3.1-rc2: CONFIG_NUMA Question
Date: Thu, 18 Aug 2011 06:51:40 -0400 (EDT) [thread overview]
Message-ID: <alpine.DEB.2.02.1108180649040.10458@p34.internal.lan> (raw)
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.
