Service availability and QoS, in terms of customer affecting performance metrics, is crucial for service systems. However, the increasing complexity in distributed service systems introduce hidden space for software faults, which undermine system availability, leading to fault or even down time. In this paper, we introduce a composition technique, Coordinated Selective Rejuvenation, to automate the...
The widespread adoption of multi-core processors in supercomputing arena results in multiple processes in one node competing for the limited resources of the network interface. This is especially true for Collective communication in MPI. InfiniBand, as a prevailing high speed network, provides fine-grained Quality of Service (QoS) through Virtual Lanes (VLs) mechanism. In this paper, we study the...
The complexity of the cluster-based Web service challenges the traditional approaches, which fail to guarantee the reliability and real-time performance required. In this paper, we present an integrated adaptive management system (JAMS) for such service. The issues we discuss address to efficiently allocate resources and provide more effective QoS support under a wide range of load conditions. For...
Some measurements of performance have been conducted in Dawning 4000 cluster. We measured the elapsed time of putting the spare instance into use to be 0.12 sec by redirection, while taking the old policy, the time for an Apache instance takes 1.05 sec. For an Oracle 10G, the cost is 7.69 sec. The spare servers contribute to a public spare resource pool. In the case of the master instance's failure,...
The complexity of the high performance Web-based application challenges the traditional approaches, which fail to guarantee the reliability and real-time performance required. In this paper, we present a prototype of a cluster-based adaptive application management system (AAMS), which is composed of the SLA event-driven global resource manager, the server resource manager and the self-adapting application...
