Detailed Description

Native parallel execution policy. This policy uses ISO C++ threads as implementation building block allowing usage in any ISO C++ compliant platform.

Constructor & Destructor Documentation

grppi::parallel_execution_native::parallel_execution_native ( )

inlinenoexcept

Default construct a native parallel execution policy.

Creates a parallel execution native object.

The concurrency degree is determined by the platform.

Note

The concurrency degree is fixed to 2 times the hardware concurrency degree.

grppi::parallel_execution_native::parallel_execution_native ( int  concurrency_degree, bool  ordering = true  )

inlinenoexcept

Constructs a native parallel execution policy.

Creates a parallel execution native object selecting the concurrency degree and ordering mode.

Parameters

concurrency_degree	Number of threads used for parallel algorithms.
order	Whether ordered executions is enabled or disabled.

Member Function Documentation

int grppi::parallel_execution_native::concurrency_degree ( ) const

inlinenoexcept

Get number of grppi trheads.

void grppi::parallel_execution_native::disable_ordering ( )

inlinenoexcept

Disable ordering.

void grppi::parallel_execution_native::enable_ordering ( )

inlinenoexcept

Enable ordering.

int grppi::parallel_execution_native::get_thread_id ( ) const

inlinenoexcept

Get index of current thread in the thread table.

Precondition

The current thread is currently registered.

bool grppi::parallel_execution_native::is_ordered ( ) const

inlinenoexcept

Is execution ordered.

template<typename T >

mpmc_queue<T> grppi::parallel_execution_native::make_queue ( ) const

inline

Makes a communication queue for elements of type T. Constructs a queue using the attributes that can be set via set_queue_attributes(). The value is returned via move semantics.

void grppi::parallel_execution_native::set_concurrency_degree ( int  degree )

inlinenoexcept

Set number of grppi threads.

void grppi::parallel_execution_native::set_queue_attributes ( int  size, queue_mode  mode  )

inlinenoexcept

Sets the attributes for the queues built through make_queue<T>()

native_thread_manager grppi::parallel_execution_native::thread_manager ( )

inline

Get a manager object for registration/deregistration in the thread index table for current thread.

Member Data Documentation

thread_pool grppi::parallel_execution_native::pool

Thread pool for lanching workers.

Note

This member is temporary and is likely to be deprecated or even removed in a future version of GrPPI.
