Sound like you want a thread_group, to which you can call
create_thread() or add_thread() in a loop then join_all():
<http://www.boost.org/doc/html/thread/thread_management.html#thread.thread_management.threadgroup>

Or you could always do silly things with recursion:
    void foo(int n = boost::thread::hardware_concurrency()) {
        if (n < 1) return;
        boost::thread bar( task, thread_data, St );
        foo(n-1);
        bar.join();
    }
