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
