inline void send_parcel(std::uint64_t tag_msb, std::uint64_t tag_lsb, std::uint64_t size, std::uint64_t target_locality_id) noexcept#

Parcel-send signal: parcel handed to parcelport (APEX shim).

Parcel-send signal: parcel handed to parcelport (no-op stub for ITTNotify).

Parcel-send signal: a parcel has been handed to the parcelport for transmission.

Parcel-send signal: parcel handed to parcelport (no-op stub).

Parameters:

  • tag_msb – High 64 bits of the parcel id.

  • tag_lsb – Low 64 bits of the parcel id. Together with tag_msb they form the full 128-bit id used to pair events across localities; lsb alone restarts per locality and would produce false matches.

  • size – Wire size of the parcel in bytes.

  • target_locality_id – Destination locality id, or naming::invalid_locality_id if unknown.

inline void recv_parcel(std::uint64_t tag_msb, std::uint64_t tag_lsb, std::uint64_t source_locality_id) noexcept#

Parcel-receive signal: parcel arrived (APEX shim).

Parcel-receive signal: parcel arrived (no-op stub for ITTNotify).

Parcel-receive signal: a parcel has arrived and its header has been deserialized.

Parcel-receive signal: parcel arrived (no-op stub).

Parameters:

  • tag_msb – High 64 bits of the parcel id.

  • tag_lsb – Low 64 bits of the parcel id.

  • source_locality_id – Sending locality id, or naming::invalid_locality_id when the parcel has no source id yet (pre-AGAS handshake parcels).

inline void parcel_scheduled(std::uint64_t tag_msb, std::uint64_t tag_lsb, std::uint64_t source_locality_id, std::uint64_t source_thread_id) noexcept#

Parcel-scheduled signal: action entered local scheduler (no-op stub for APEX).

Parcel-scheduled signal: action entered local scheduler (no-op stub for ITTNotify).

Parcel-scheduled signal: an action carried by a parcel has been placed onto the local scheduler. Fires for deferred receives (zero-copy or multi-parcel message), for AGAS-routed parcels, and for parcels the AGAS re-route chain delivered after a migration detection. Does not fire for the non-deferred path where load_schedule schedules inline.

Parcel-scheduled signal: action entered local scheduler (no-op stub).

Parameters:

  • tag_msb – High 64 bits of the parcel id.

  • tag_lsb – Low 64 bits of the parcel id.

  • source_locality_id – Sending locality id (see recv_parcel).

  • source_thread_id – Parent HPX thread id captured on the sender; may be 0 when unavailable.
