Functions

inline int init(std::function<int(hpx::program_options::variables_map&)> f, int argc, char **argv, init_params const &params = init_params())#

Main entry point for launching the HPX runtime system.

This is the main entry point for any HPX application. This function (or one of its overloads below) should be called from the users main() function. It will set up the HPX runtime environment and schedule the function given by f as a HPX thread. This overload will not call hpx_main.

This is the main entry point for any HPX application. This function (or one of its overloads below) should be called from the users main() function. It will set up the HPX runtime environment and schedule the function given by f as a HPX thread.

Note

If the parameter mode is not given (defaulted), the created runtime system instance will be executed in console or worker mode depending on the command line arguments passed in argc/argv. Otherwise it will be executed as specified by the parametermode.

Parameters

  • f – [in] The function to be scheduled as an HPX thread. Usually this function represents the main entry point of any HPX application. If f is nullptr the HPX runtime environment will be started without invoking f.

  • argc – [in] The number of command line arguments passed in argv. This is usually the unchanged value as passed by the operating system (to main()).

  • argv – [in] The command line arguments for this application, usually that is the value as passed by the operating system (to main()).

  • params – [in] The parameters to the hpx::init function (See documentation of hpx::init_params)

Returns

The function returns the value, which has been returned from the user supplied f.

This is the main entry point for any HPX application. This function (or one of its overloads below) should be called from the users main() function. It will set up the HPX runtime environment and schedule the function given by f as a HPX thread.

Note

Parameters

  • f – [in] The function to be scheduled as an HPX thread. Usually this function represents the main entry point of any HPX application. If f is nullptr the HPX runtime environment will be started without invoking f.

  • argc – [in] The number of command line arguments passed in argv. This is usually the unchanged value as passed by the operating system (to main()).

  • argv – [in] The command line arguments for this application, usually that is the value as passed by the operating system (to main()).

  • params – [in] The parameters to the hpx::init function (See documentation of hpx::init_params)

Returns

The function returns the value, which has been returned from the user supplied f.

inline int init(int argc, char **argv, init_params const &params = init_params())#

Main entry point for launching the HPX runtime system.

This is the main entry point for any HPX application. This function (or one of its overloads below) should be called from the users main() function. It will set up the HPX runtime environment and schedule the function given by f as a HPX thread. This overload will not call hpx_main.

This is the main entry point for any HPX application. This function (or one of its overloads below) should be called from the users main() function. It will set up the HPX runtime environment and schedule the function given by f as a HPX thread.

Note

If the parameter mode is not given (defaulted), the created runtime system instance will be executed in console or worker mode depending on the command line arguments passed in argc/argv. Otherwise it will be executed as specified by the parametermode.

Parameters

  • argc – [in] The number of command line arguments passed in argv. This is usually the unchanged value as passed by the operating system (to main()).

  • argv – [in] The command line arguments for this application, usually that is the value as passed by the operating system (to main()).

  • params – [in] The parameters to the hpx::init function (See documentation of hpx::init_params)

Returns

The function returns the value, which has been returned from the user supplied f.

inline int init(std::nullptr_t f, int argc, char **argv, init_params const &params = init_params())#

Main entry point for launching the HPX runtime system.

This is the main entry point for any HPX application. This function (or one of its overloads below) should be called from the users main() function. It will set up the HPX runtime environment and schedule the function given by f as a HPX thread. This overload will not call hpx_main.

This is the main entry point for any HPX application. This function (or one of its overloads below) should be called from the users main() function. It will set up the HPX runtime environment and schedule the function given by f as a HPX thread.

Note

If the parameter mode is not given (defaulted), the created runtime system instance will be executed in console or worker mode depending on the command line arguments passed in argc/argv. Otherwise it will be executed as specified by the parametermode.

Parameters

  • f – [in] The function to be scheduled as an HPX thread. Usually this function represents the main entry point of any HPX application. If f is nullptr the HPX runtime environment will be started without invoking f.

  • argc – [in] The number of command line arguments passed in argv. This is usually the unchanged value as passed by the operating system (to main()).

  • argv – [in] The command line arguments for this application, usually that is the value as passed by the operating system (to main()).

  • params – [in] The parameters to the hpx::init function (See documentation of hpx::init_params)

Returns

The function returns the value, which has been returned from the user supplied f.

inline int init(init_params const &params = init_params())#

Main entry point for launching the HPX runtime system.

This is a simplified main entry point, which can be used to set up the runtime for an HPX application (the runtime system will be set up in console mode or worker mode depending on the command line settings).

This is a simplified main entry point, which can be used to set up the runtime for an HPX application (the runtime system will be set up in console mode or worker mode depending on the command line settings).

Note

The created runtime system instance will be executed in console or worker mode depending on the command line arguments passed in argc/argv. If not command line arguments are passed, console mode is assumed.

Note

If no command line arguments are passed the HPX runtime system will not support any of the default command line options as described in the section ‘HPX Command Line Options’.

Parameters

params – [in] The parameters to the hpx::init function (See documentation of hpx::init_params)

Returns

The function returns the value, which has been returned from hpx_main (or 0 when executed in worker mode).
