Chai

v1.0-alpha

Overview

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. This release includes the OpenCL-D, OpenCL-U, CUDA-D, CUDA-U, CUDA-D-Sim, and CUDA-U-Sim implementations. The C++AMP implementations are underway. If you would like early access to premature versions, please contact us.
