Re: [Starpu-devel] starpu_task_destroy

Sorry I was not concise in my previous email. The confusion actually started while looking into examples/openmp/vector_scal.c code as there you are using starpu_task_destroy(task) for task created with starpu_task_create() without explicitly setting destroy..

Then, just skimming through doc at starpu_task_destroy description I got bit confused:

— Function: void starpu_task_destroy (struct starpu_task *task)

Free the resource allocated during starpu_task_create and associated with task. This function can be called automatically after the execution of a task by setting the destroy flag of the starpu_task structure (default behaviour). Calling this function on a statically allocated task results in an undefined behaviour.

and default value of destroy field says "0"

But then looking more into starpu_task_create() and destroy field description in doc it became clearer. So in brief, there is no conflicting statement in doc however the information looks a bit scattered to me.

While reading doc, there is slight confusion about starpu_task_destroy and how

it behaves with starpu_task_create.

Where is it so?  If there is confusion anywhere, we have to fix it. What
I currently see it is always said that task created by
starpu_task_create() are automatically freed, is there any place where
it is not so?

(I'll answer OpenMP separately, since it's a completely different
matter)
