The parameter \p asynchronous indicates whether the function should block or not. In the case of an asynchronous call, it is possible to synchronize with the termination of this operation either by the means of implicit dependencies (if enabled) or by calling starpu_task_wait_for_all(). If \p callback_func is not NULL, this callback function is executed after the handle has been copied, and it is given the pointer \p callback_arg as argument. \fn void starpu_execute_on_each_worker(void (*func)(void *), void *arg, uint32_t where) \ingroup API_Miscellaneous_Helpers This function executes the given function on a subset of workers. When calling this method, the offloaded function \p func is executed by every StarPU worker that may execute the function. The argument \p arg is passed to the offloaded function. The argument \p where specifies on which types of processing units the function should be executed. Similarly to the field starpu_codelet::where, it is possible to specify that the function should be executed on every CUDA device and every CPU by passing ::STARPU_CPU|::STARPU_CUDA. This function blocks until the function has been executed on every appropriate processing units, so that it may not be called from a callback function for instance. */
