Subject: [Boost-users] Create A Boost Thread for each HW Thread?
From: Brad (boost_at_[hidden])

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;
}
if ( t == 2 )
{
boost::thread _01( task, thread_data, St );
boost::thread _02( task, thread_data, St );
_01.join();
_02.join();
}
if ( t == 4 )
{
boost::thread _01( task, thread_data, St );
boost::thread _02( task, thread_data, St );
boost::thread _03( task, thread_data, St );
boost::thread _04( task, thread_data, St );
_01.join();
_02.join();
_03.join();
_04.join();
}
It seems that a for loop (or something similar) could be used to start
the same number of boost threads as there are HWTs.
Could someone point me in the right direction?
Thanks,
Brad
