The Parallelization Project - New designs of domain specific accelerators and their compilers
As state-of-the-art smartphones, tablet, laptops and servers adopt multicore processors with GPUs and custom accelerators, computer systems become increasingly parallel and heterogeneous. The parallelization project investigates domain specific programs such as deep learning and scientific applications to find hardware acceleration opportunities, and proposes new hardware acceleration architecture and their compilers.
