numaplace tool

Cliff, Filipe et al,

I've been developing a tool called numaplace [1,2] which gives run-time task affinity; this is needed when booting with the 'isolcpus' kernel parameter.

Secondly, it dynamically allocates (and locks out) cores at task-creation time, giving a kind of run-time resource scheduling; this allows users to execute OpenMP/threaded/multi-process applications without preparing environment variables with explicit list of cores.

Later, I'll add NUMA locality guidance for improved spatial locality.

The numactl package seems a natural place to contribute this to, yes?

Many thanks!
Daniel
