Data Structures
struct	_ocl
	Structure that contains basic OpenCL objects for arbitrary computations. More...
struct	_task
	Simple representation of a task. More...
struct	_taskgroup
	A collection of tasks for the same callback function. More...

Macros
#define	CL_CHECK(res)
#define	SCHEDULE_OPENCL(cpu_threads, gpu_threads, func, ...)
	Macro that simplifies the use of the task scheduler. More...

Typedefs
typedef struct _task	task
	Abbreviation for a struct _task.
typedef task *	ptask
	Abbreviation for a pointer to a struct _task.
typedef struct _taskgroup	taskgroup
	Abbreviation for a struct _taskgroup.
typedef taskgroup *	ptaskgroup
	Abbreviation for a pointer to a struct _taskgroup.

Enumerations
enum	task_affinity { CPU_ONLY, GPU_ONLY, CPU_FIRST, GPU_FIRST }
	This enum specifies the affinity of exceution of a taskgroup. More...

Functions

	Create a new list of tasks with the same code to execute. More...
void	del_taskgroup (ptaskgroup tg)
	Delete a taskgroup object. More...
void	add_task_taskgroup (ptaskgroup *tg, void *data)
	Adds a new _task to a _taskgroup. More...
void	add_taskgroup_to_scheduler (ptaskgroup tg)
	Enqueues a full taskgroup to the execution queue of the scheduler. More...
void	start_scheduler (uint cpu_threads, uint gpu_threads)
