Inheritance diagram for ttg_parsec::Buffer< T, Allocator >:

Documentation

template<typename T, typename Allocator>
struct ttg_parsec::Buffer< T, Allocator >

A buffer that is mirrored between host memory and different devices. The runtime is free to move data between device and host memory based on where the tasks are executing.

Note that a buffer is movable and should not be shared between two objects (e.g., through a pointer) in order for TTG to properly facilitate ownership tracking of the containing object.

Definition at line 40 of file buffer.h.
