2019 CCF Transactions on High Performance Computing  
We in this work evaluate and analyze eight sparse matrix and graph kernels on an AMD CPU-GPU heterogeneous processor by using 956 sparse matrices.  ...  We finally discuss several challenges and opportunities for achieving higher performance for sparse matrix and graphs kernels on heterogeneous processors.  ...  Acknowledgements This work has been partly supported by the National Natural Science Foundation of China (Grant nos. 61732014, 61802412, 61671151), Beijing Natural Science Foundation (no. 4172031), and  ...

Thirdly, this thesis devised methods for carrying out result visualization directly on GPU by storing processed data in local GPU memory through making use of GPU's rendering device features to achieve  ...  of stream processing pattern represented by the compute unified device architecture (CUDA) in which GPU is considered as iii not only a graphics device but a streaming coprocessor of CPU.  ...  Similar to CUDA, OpenCL also employed the concepts of "host programs" and "kernels".  ...
