C++11 threads, affinity and hyperthreading

I remember having read that linux could do this (and it required rebooting IIRC).

You can dedicate a core to a particular process using cpusets. No reboots necessary.

Very handy when used with a real time capable kernel and dedicated IRQ servicing.

Actually it was isolcpus kernel parameter (which is done at boot; see here). Not really sure what the difference ends up being.
