/*! \defgroup API_Parallel_Tasks Parallel Tasks

\fn int starpu_combined_worker_get_size(void)
\ingroup API_Parallel_Tasks
Return the size of the current combined worker, i.e. the total number
of cpus running the same task in the case of ::STARPU_SPMD parallel
tasks, or the total number of threads that the task is allowed to
start in the case of ::STARPU_FORKJOIN parallel tasks.

\fn int starpu_combined_worker_get_rank(void)
\ingroup API_Parallel_Tasks
Return the rank of the current thread within the combined worker. Can
only be used in ::STARPU_FORKJOIN parallel tasks, to know which part
of the task to work on.

\fn unsigned starpu_combined_worker_get_count(void)
\ingroup API_Parallel_Tasks
Return the number of different combined workers.

\fn int starpu_combined_worker_get_id(void)
\ingroup API_Parallel_Tasks
Return the identifier of the current combined worker.

\fn int starpu_combined_worker_assign_workerid(int nworkers, int workerid_array[])
\ingroup API_Parallel_Tasks
Register a new combined worker and get its identifier

\fn int starpu_combined_worker_get_description(int workerid, int *worker_size, int **combined_workerid)
\ingroup API_Parallel_Tasks
Get the description of a combined worker

\fn int starpu_combined_worker_can_execute_task(unsigned workerid, struct starpu_task *task, unsigned nimpl)
\ingroup API_Parallel_Tasks
Variant of starpu_worker_can_execute_task() compatible with combined
workers

\fn void starpu_parallel_task_barrier_init(struct starpu_task *task, int workerid)
\ingroup API_Parallel_Tasks
Initialise the barrier for the parallel task, and dispatch the task
between the different combined workers.
