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.
