Research Abstract

A virtualization technique has been proposed to hide the heterogeneous configuration of different processors, by automatic task allocation considering their strengths and weaknesses. OpenCL has also been applied to programming of large-scale systems of various computing nodes. For high dependability, a transparent checkpoint restart mechanism for OpenCL applications has been developed. This work also investigated the practicality and limitations of OpenACC.
