stdgpu 1.0.0 (2019-08-19)

This is the first public version of stdgpu, an open-source C++ library providing generic STL-like GPU data structures for fast and reliable data management. The main components of the library are:

  • Core: A collection of core features including configuration and platform management, a simple contract interface as well as a robust memory and iterator concept.
  • Container: A set of robust containers for GPU programming with an STL-like design consisting of sequential and hash-based data structures.
  • Utilities: A variety of utility functions supporting the container component and general GPU programming.
