Concurrency::tile_barrier Class Reference

The tile_barrier class is a capability class that is only creatable by the system, and passed to a tiled parallel_for_each lambda as part of the tiled_index parameter. It provides wait methods whose purpose is to synchronize execution of threads running within the thread group (tile). More...

Member Function Documentation

void Concurrency::tile_barrier::wait ( ) const

inline

Blocks execution of all threads in a tile until all all threads in the tile have reached this call. Ensures that memory accesses are visible to other threads in the thread tile, and are executed according to program order

    {
        __dp_d3d_all_memory_fence_with_tile_barrier();
    }

void Concurrency::tile_barrier::wait_with_all_memory_fence ( ) const

inline

Blocks execution of all threads in a tile until all all threads in the tile have reached this call. Ensures that memory accesses are visible to other threads in the thread tile, and are executed according to program order

    {
        __dp_d3d_all_memory_fence_with_tile_barrier();
    }

void Concurrency::tile_barrier::wait_with_global_memory_fence ( ) const

inline

Blocks execution of all threads in a tile until all all threads in the tile have reached this call. Ensures that global memory accesses are visible to other threads in the thread tile, and are executed according to program order

    {
        __dp_d3d_device_memory_fence_with_tile_barrier();
    }

void Concurrency::tile_barrier::wait_with_tile_static_memory_fence ( ) const

inline

Blocks execution of all threads in a tile until all all threads in the tile have reached this call. Ensures that tile_static memory accesses are visible to other threads in the thread tile, and are executed according to program order

    {
        __dp_d3d_tile_static_memory_fence_with_tile_barrier();
    }
