The framework is based on the event channel abstraction which allows circumventing the main drawbacks of the layered-based approach traditionally used to develop such protocols, whilst at the same time providing a flexible, simple and well structured way to implement them. The event channel service provided by EVA establishes how entities that share the same address space interact. Then, the application designer has the opportunity to define the most appropriate lower level communication protocols that control the way entities that execute within different processes will interact. The framework specifies a way to accommodate these protocols and provides several standard protocol implementations. Further a development methodology is described for constructing applications on top of the framework. In designing the framework, we have followed the approach of using, whenever possible, well established concepts, thus the paper also discusses the utilisation of such concepts in improving both the efficiency and the structuring of the framework and of the applications to be built on top of it.","PeriodicalId":385607,"journal":{"name":"Proceedings IEEE International Symposium on Network Computing and Applications.

In this paper we present an in-depth description of how the Quadrics network supports both hardware- and software-based collectives. We describe the main features of the two building blocks of this network, a network interface that can perform zero-copy user-level communication and a wormhole routing switch. We also focus our attention on the routing and flow control algorithms, deadlock avoidance and on how the processing nodes are integrated in a global, virtual shared memory. Experimental results conducted on 64-node AlphaServer cluster indicate that the time to complete the hardware-based barrier synchronization on the whole network is as low as 6 /spl mu/s, with very good scalability. Good latency and scalability are also achieved with the software-based synchronization, which takes about 15 /spl mu/s. With the broadcast, similar performance is achieved by the hardware- and software-based implementations, which can deliver messages of up to 256 bytes in 13 /spl mu/s and can get a sustained asymptotic bandwidth of 288 Mbytes/sec on all the nodes. The hardware-based barrier is almost insensitive to the network congestion, with 93% of the synchronizations taking less than 20 /spl mu/s when the network is flooded with a background traffic of unicast messages. On the other hand, the software-based implementation suffers from a significant performance degradation. With high load the hardware broadcast maintains a reasonably good latency, delivering messages up to 2KB in 200 /spl mu/s, while the software broadcast suffers from slightly higher latencies inherited from the synchronization mechanism. Both broadcast algorithms experience a significative performance degradation of the sustained bandwidth with large messages.","PeriodicalId":385607,"journal":{"name":"Proceedings IEEE International Symposium on Network Computing and Applications.

Most of this processing speed stems from employing latest high-performance network processor or multiprocessors as the forwarding engine of the router However, all these improvements have been proposed without any detailed study in performance evaluation. The impact of instruction level parallelism, branch prediction, multiprocessing, and cache architectures on the performance of routers is not known. In the paper a methodology is proposed, which extends an execution-driven simulator to evaluate router architectures. We incorporate the exact model of an IP router into RSIM to analyze its performance and also develop a framework for feeding real Internet traces to the simulator Our work enables us to vary system parameters to simulate and analyze designs of realistic system with a range of traces. It is shown that the performance of Internet routers can be dramatically enhanced by using multiprocessor architectures. The router design also considers various cache replacement policies and router arbitration policies.","PeriodicalId":385607,"journal":{"name":"Proceedings IEEE International Symposium on Network Computing and Applications.
