英文摘要： Currently,Big Data processing in different areas,such as commercial intelligence, social management and scientific computing, has requirements ofhigh performance and low latency, leading to serious challenges for time-efficient computing in traditional data processing infrastructures. This raises urgent needs of significant renovations in the data access methods, processing hardware and software supporting for Big Data. Accordingly, we propose to research on the architecture and key technology of high performance and time-efficient parallel computer for Big Data. In the aspect of parallel computer architecture, we focus on the high performance accelerator architecture and the scalable heterogeneous parallel computing system architecture. In the aspect of hybrid main memory, we will mainly explore the streaming and high concurrent main memory structures and the optimization mechanisms for the data management of hybrid main memory. In the aspect of parallel processing software supporting, we will mainly study the heterogeneous platform-based task-granularity partitioning and efficient planning mechanism as well as the data layouts mechanisms targeting high throughput and low latency. At last, we will evaluate and verify our research results through experiments over Big Data collections from real-world applications. This project has both significant academic value and application prospect. The research results will provide fundamental theory, methods and techniques for designing and developing high performance and time-efficient computer systems for Big Data analysis and processing.
