Oliver Kowalke, the author of the Boost.ThreadPool has posted a compressed file boost-bind_processor.v1.tar.gz  in Boost Vault http://www.boostpro.com/vault/index.php?directory=Concurrent%20Programming&PHPSESSID=96307fee8086c06036af42fae790b449

This file contains functions which allows bind/unbind current thread to a processor 

boost::this_thread::bind_to_processor( unsigned int n); // thread gets bound to processor n

boost::this_thread::bind_to_any_processor(); // thread can be scheduled to all available processors

Both functions will throw boost::system_error. Processors are enumerated starting at 0.

HTH,
