报告简介：Supercomputing has received long-missed intensive attentions from industry and academia recently. This renewed interest is due to two new developments in computing: Cloud computing and multicore/manycore systems. Cloud computing uses a cloud of computers, usually a cluster of supercomputers, and Grid technology to provide virtual computers on demand. Multicore/manycore processors put many cores into one chip to overcome the physical constraints of a single processor and deliver high computing power on one chip. Cloud computing requires huge computing power to meet ever increasing users’ demand, whereas multicore/manycore systems make parallel processing a norm of computing. Both of them, however, face the scalability issue: how to scale up the capacity? In this talk we first introduce the concept and motivation of Cloud computing and multicore/manycore architecture, discuss the difference between Grid and Cloud computing. Then we study scalability issues, especially the scalability of multicore/manycore architectures. We conclude with an identified scalability bottleneck and its corresponding suggested solutions.
