集群内集体通信的性能表征
Performance Characterisation of Intra-Cluster Collective Communications
摘要：
虽然最近的作品试图通过分离集群内和集群间的通信来改善网格系统中的集体通信，但通信的优化只关注集群间的通信。相反，我们认为，应用程序的整体性能可能会得到改善，如果集群内集体通信性能是已知的。因此，有一个准确的集群内集体通信的模型是很重要的，它提供了必要的证据来调整和预测其性能正确。在本文中，我们提出了我们的经验，这样的沟通策略建模。我们描述和比较不同的实施策略与他们的通信模型，评估模型的准确性和描述的实际挑战时，可以发现建模集体通信。
英文摘要：
Although recent works try to improve collective communication in grid systems by separating intra and inter-cluster communication, the optimisation of communications focus only on inter-cluster communications. We believe, instead, that the overall performance of the application may be improved if intra-cluster collective communications performance is known in advance. Hence, it is important to have an accurate model of the intra-cluster collective communications, which provides the necessary evidences to tune and to predict their performance correctly. In this paper we present our experience on modelling such communication strategies. We describe and compare different implementation strategies with their communication models, evaluating the models' accuracy and describing the practical challenges that can be found when modelling collective communications.
