Variables

struct get_pu_mask_t : public hpx::functional::detail::tag_fallback<get_pu_mask_t>#

#include <execution_information.hpp>

Retrieve the bitmask describing the processing units the given thread is allowed to run on

All threads::executors invoke sched.get_pu_mask().

Note

If the executor does not support this operation, this call will always invoke hpx::threads::get_pu_mask()

Param exec: [in] The executor object to use for querying the number of pending tasks.
Param topo: [in] The topology object to use to extract the requested information.
Param thream_num: [in] The sequence number of the thread to retrieve information for.

Private Functions

struct has_pending_closures_t : public hpx::functional::detail::tag_fallback<has_pending_closures_t>#

#include <execution_information.hpp>

Retrieve whether this executor has operations pending or not.

Note

If the executor does not expose this information, this call will always return false

Param exec: [in] The executor object to use to extract the requested information for.

Private Functions

template<typename Executor> requires (hpx::traits::is_executor_any_v< Executor >) friend decltype(auto) tag_fallback_invoke(has_pending_closures_t

template<typename Executor> Executor && requires (hpx::traits::is_executor_any_v< Executor > &&detail::has_has_pending_closures_v< Executor >) friend decltype(auto) tag_invoke(has_pending_closures_t

Private Members

Executor Executor && exec {return HPX_FORWARD(Executor, exec).has_pending_closures()

struct set_scheduler_mode_t : public hpx::functional::detail::tag_fallback<set_scheduler_mode_t>#

#include <execution_information.hpp>

Set various modes of operation on the scheduler underneath the given executor.

Note

This calls exec.set_scheduler_mode(mode) if it exists; otherwise it does nothing.

Private Functions

template<typename Executor, typename Mode> requires (hpx::traits::is_executor_any_v< Executor >) friend void tag_fallback_invoke(set_scheduler_mode_t
