mps_thread_pool Struct Reference

A thread pool that contains a set of mps_thread and allow to manage them as a set of worker. More...

#include <threading.h>

Public Attributes
unsigned int	n
	The numer of thread in the thread pool.
unsigned int	concurrency_limit
	Limit to the maximum spawnable number of threads. This can be set to 0 that means "No limit". It is useful when less concurrency is desired without deleting and recreating threads.
mps_thread *	first
	A pointer to the first thread in the thread pool.
mps_thread_pool_queue *	queue
	Queue of the work that shall be consumed by the threads.
pthread_mutex_t	queue_changed_mutex
	Mutex associated to the queue_changed condition.
pthread_cond_t	queue_changed
	Condition that is notified when the queue changes.
pthread_mutex_t	work_completed_mutex
pthread_cond_t	work_completed_cond
int	busy_counter
mps_boolean	strict_async
	When this vaulue is set to true every call to mps_assign_job returns immediately.

concurrency_limit

unsigned int mps_thread_pool::concurrency_limit

Limit to the maximum spawnable number of threads. This can be set to 0 that means "No limit". It is useful when less concurrency is desired without deleting and recreating threads.

This variables MUST be updated using the accessor function mps_thread_pool_set_

strict_async

mps_boolean mps_thread_pool::strict_async

When this vaulue is set to true every call to mps_assign_job returns immediately.

When it is set to false the calls to mps_thread_pool_assign() when the number of thread is set to 1 will immediately perform the work, instead of delegating it to a background thread. This is done to ensure reasonable performance for the cases where only 1 CPU is available on the PC.
