What's the proper way to start a boost thread for each hardware thread available? I can do this... but it is clunky and does not scale (especially when there are lots of cores):

const unsigned int hwt() {          const unsigned int t = boost::thread::hardware_concurrency();          return t; }

try boost::thread_group [1]

boost::thread_group tg;

for (int i  =0; i < hwt(); ++i) {  tg.create_thread(...); } tg.join_all();

Best regards, Christoph

I'm not sure if this was also part of the question, but even if not, I'm also curious: Is there a boost-ey way of setting the affinity so that the threads are pinned to physical cores? I have my own wrappers at the moment, but I'd love to use something from boost, if available. Thanks, Brian
