Chai is a benchmark suite of Collaborative Heterogeneous Applications for Integrated-architectures. The Chai benchmarks are designed to use the latest features of heterogeneous architectures such as shared virtual memory and system-wide atomics to achieve efficient simultaneous collaboration between host and accelerator devices.

Each benchmark has multiple implementations: OpenCL-U, OpenCL-D, CUDA-U, CUDA-D, CUDA-U-Sim, CUDA-D-Sim, and C++AMP. The versions suffixed with -U use unified memory and system-wide atomics while the versions suffixed with -D use the traditional communication techniques of discrete architectures. The versions suffixed with -Sim run on the gem5-gpu simulator.

Check out our Getting Started page for instructions on how to download and use the benchmarks.
