Linux Gains Support for NUMA

Posted by CowboyNeal on from the big-iron-at-your-hip dept.

soosterh writes "CNet has an article about a NUMA patch from IBM. It says that the improvement adds some support in Linux for nonuniform memory access, or NUMA, a design for higher-end servers with many processors. Linus Torvalds, the original creator of the operating system and still its top authority, accepted the update this month into version 2.5, the current test version of the software."

    Not only is this beneficial for large computers, but also on smaller SMP systems with hyperthreading. On CPU's with hyperthreading,
    it's often faster for a process to reside on the same CPU but not necessary the same 'virtual' CPU when accessing memory.
    And alot of 8way+ systems are NUMA whether or not they are advertised as such.
