Here are some preliminary results from simple benchmarks on a
4-node, 32 CPU core (4x8 core) Dell PowerEdge R910 system.

For the simple linpack streams benchmark, both sched/numa and
autonuma are within the margin of error compared to manual
tuning of task affinity.  This is a big win, since the current
upstream scheduler has regressions of 10-20% when the system
runs 4 through 16 streams processes.

For specjbb, the story is more complicated. After fixing the
obvious bugs in sched/numa, and getting some basic cpu-follows-memory
code (not yet in -tip AFAIK), Larry, Peter and I, averaged results
look like this:

baseline: 	246019
manual pinning: 285481 (+16%)
autonuma:	266626 (+8%)
sched/numa:	226540 (-8%)

This is with newer sched/numa code than what is in -tip right now.
Once Peter pushes the fixes by Larry and me into -tip, as well as
his cpu-follows-memory code, others should be able to run tests
like this as well.

Now for some other workloads, and tests on 8 node systems, etc...


Full results for the specjbb run below:
