Hybrid OpenCL: Connecting Different OpenCL Implementations over Network

We are developing Hybrid OpenCL, which enables the connection between different OpenCL implementations over the network. Hybrid OpenCL consists of two elements, a runtime system that provides the abstraction of different OpenCL implementations and a bridge program that connects multiple OpenCL runtime systems over the network. Hybrid OpenCL enables the construction of the scalable OpenCL environments. It enables applications written in OpenCL to be easily ported to high performance cluster computers; thus, Hybrid OpenCL can provide more various parallel computing platforms and the progress of utility value of OpenCL applications. This paper describes the implementation of Hybrid OpenCL and its results from experimentation. The experimental results show that the overhead introduced by Hybrid OpenCL is minimum and can be amortized by actual data processing time.
