Simple NUMA policy support. It consists of a numactl program to run other programs with a specific NUMA policy and a libnuma shared library ("NUMA API") to set NUMA policy in applications.
The libnuma binary interface is supposed to stay binary compatible.
Incompatible changes will use new symbol version numbers.
In addition there are various test and utility programs, like
display NUMA allocation statistics and
test/ there is a small regression test suite.
regress assumes a unloaded machine with memory free on each node.
Otherwise you will get spurious failures in the non-strict policies (prefered,

numactl and the demo programs are under the GNU General Public License, v.2.
libnuma is under the GNU Lesser General Public License, v2.1.
The manpages are under the same license as the Linux manpages (see the files.)
numademo links with a library derived from the C version of STREAM by John D.
McCalpin and Joe R. Zagar for one sub benchmark. See
stream_lib.c for the
license. In particular when you publish
numademo output you might need to pay
attention there or filter out the STREAM results.
It also uses a public domain Mersenne Twister implementation from Michael Brundage.
