Detailed Description

Manages a collection of threads.

The thread_group object performs limited exception forwarding. exception throws within a thread of type const char* will be caught and forwarded to the join() function. If the call to join() is wrapped by a try-catch block, the exception will be caught safely and thread cleanup will be completed properly.

If multiple threads are running in the thread-group, the master should test if running_threads() is > 0, and retry the join().

Member Function Documentation

void graphlab::thread_group::join

(

)

Waits for all threads to complete execution. const char* exceptions

thrown by threads are forwarded to the join() function.

void graphlab::thread_group::launch

(

const boost::function< void(void)> &

spawn_function

)

Launch a single thread which calls spawn_function No CPU affinity is set so which core it runs on is up to the OS Scheduler

void graphlab::thread_group::launch	(	const boost::function< void(void)> &	spawn_function,
		size_t	cpu_id
	)

Launch a single thread which calls spawn_function Also sets CPU Affinity
