Re: NetBSD # actual cores

Maybe hwloc (https://www.open-mpi.org/projects/hwloc/) helps? The version in pkgsrc (parallel/hwloc) is quite outdated, but I guess it should run out of the box.

Does anyone know how to get the number of complete cores on a
hyperthreaded CPU under NetBSD?

On FreeBSD it's sysctl kern.smp.cores.
On Darwin it's sysctl hw.physicalcpu.

I'm not seeing an equivalent on NetBSD.  hw.ncpu reports total
hyperthreads, as it does on the other platforms.

I need this to fix py-joblib, where upstream lacks support for BSDs.

Thanks...
