An Integrated Architecture for QoS-Enable Router and Grid-Oriented Supercomputer

Abstract

The overall performance of networking computation is determined by the grid node computer and the network infrastructure under it. But the grid node computer currently in use is not designed for grid applications. At same time, router capacity is getting more and more powerful. To Combine high performance router with traditional supercomputer will be a feasible way for both supercomputing and high performance QoS routing. At one side, it can release the node computer from the networking overhead and focus on computing and data processing, At the other side, it bring more powerful computing power to router and enable it to meet stream-based QoS and security processing requirement. This paper proposed an innovative integrated architecture AQRGS(Architecture for QoS-enable Router and Grid–oriented Supercomputer), which makes the CPUs focus on their high performance computing and data processing and leave the network communication jobs to the more specialized network processors in the high performance router. Thus the computing and communication capability of the grid node computers will be both highly improved and the grid application will run much faster. This paper discussed the related issues of building a grid oriented parallel computer integrating the network processing, which can also be benefit for QoS processing when used as a high performance router.
