In this paper, we propose a new OpenCL toolkit called JCL for heterogeneous clusters. Using this toolkit, users can make use of multiple remote heterogeneous processors including CPUs and GPUs for the execution of their OpenCL programs. Since load balance is an important issue for the performance of the user programs executed by heterogeneous processors, the proposed toolkit provides users with a set of load-balancing functions to automatically adjust the amount of data assigned to each processor according to processor’s computation power. We have evaluated the performance of the proposed toolkit in this paper. Our experimental result shows that the proposed toolkit really can enable the test programs to effectively exploit heterogeneous processors for enhancing their execution performance.
