An Automatic Device Memory Allocation Method for OpenMPC

Abstract (in Japanese) (See Japanese page) 
(in English) The CUDA programming model provides better abstraction for GPU programming. However, it is still hard to build program because some specific techniques and knowledge about GPU architecture are required. Hence, many frameworks for CUDA have been developed. OpenMPC is one of them based on OpenMP. OpenMPC is an easy-to-write framework for programmers familiar with traditional OpenMP, but still requires programmers to use special directives for using fast device memories. To solve this problem, this paper propses a method for allocating data on appropriate device memories automatically. This paper also propses a method for allocating data, which are transferred between host and device, on page locked memory. The experiment results with several programs show that proposed methods can reduce 52% execution time in maximum.
