Variables

static const colocating_distribution_policy colocated = {}#

A predefined instance of the co-locating distribution_policy. It will represent the local locality and will place all items to create here.

struct colocating_distribution_policy#
#include <colocating_distribution_policy.hpp>

This class specifies the parameters for a distribution policy to use for creating a given number of items on the locality where a given object is currently placed.

Public Functions

constexpr colocating_distribution_policy() = default#

Default-construct a new instance of a colocating_distribution_policy. This policy will represent the local locality.

inline colocating_distribution_policy operator()(id_type const &id) const#

Create a new colocating_distribution_policy representing the locality where the given object is current located

Parameters

id – [in] The global address of the object with which the new instances should be colocated on

template<typename Client, typename Stub, typename Data>
inline colocating_distribution_policy operator()(client_base<Client, Stub, Data> const &client) const#

Create a new colocating_distribution_policy representing the locality where the given object is current located

Parameters

client – [in] The client side representation of the object with which the new instances should be colocated on

template<typename Component, typename ...Ts>
inline hpx::future<hpx::id_type> create(Ts&&... vs) const#

Create one object on the locality of the object this distribution policy instance is associated with

Note

This function is part of the placement policy implemented by this class

Parameters

vs – [in] The arguments which will be forwarded to the constructor of the new object.

Returns

A future holding the global address which represents the newly created object

template<typename Component, typename ...Ts>
inline hpx::future<std::vector<bulk_locality_result>> bulk_create(std::size_t count, Ts&&... vs) const#

Create multiple objects colocated with the object represented by this policy instance

Note

This function is part of the placement policy implemented by this class

Parameters
  • count – [in] The number of objects to create

  • vs – [in] The arguments which will be forwarded to the constructors of the new objects.

Returns

A future holding the list of global addresses which represent the newly created objects

inline async_result<Action>::type async(launch policy, Ts&&... vs) const#
template<typename Action, typename Callback, typename ...Ts>
inline async_result<Action>::type async_cb(launch policy, Callback &&cb, Ts&&... vs) const#

Note

This function is part of the invocation policy implemented by this class

template<typename Action, typename Continuation, typename ...Ts>
inline bool apply(Continuation &&c, launch policy, Ts&&... vs) const#

Note

This function is part of the invocation policy implemented by this class

template<typename Action, typename ...Ts>
inline bool apply(launch policy, Ts&&... vs) const#
template<typename Action, typename Continuation, typename Callback, typename ...Ts>
inline bool apply_cb(Continuation &&c, launch policy, Callback &&cb, Ts&&... vs) const#

template<typename Action, typename Callback, typename ...Ts>
inline bool apply_cb(launch policy, Callback &&cb, Ts&&... vs) const#
inline hpx::id_type get_next_target() const#

Returns the locality which is anticipated to be used for the next async operation

Public Static Functions

static inline std::size_t get_num_localities()#

Returns the number of associated localities for this distribution policy

Note

This function is part of the creation policy implemented by this class

template<typename Action>
struct async_result#
#include <colocating_distribution_policy.hpp>

Note

This function is part of the invocation policy implemented by this class
