Building MapReduce applications using the Message-Passing Interface (MPI) enables us to exploit the performance of large HPC clusters for big data analytics. However, due to the lacking of native fault tolerance support in MPI and the incompatibility between the MapReduce fault tolerance model and HPC schedulers, it is very hard to provide a fault tolerant MapReduce runtime for HPC clusters. We propose...
Although the resource elasticity offered by Infrastructure-as-a-Service (IaaS) clouds opens up opportunities for elastic application performance, it also poses challenges to application management. Cluster applications, such as multi-tier websites, further complicates the management requiring not only accurate capacity planning but also proper partitioning of the resources into a number of virtual...
Performance control and power management in virtualized machines (VM) are two major research issues in modern data centers. They are challenging due to complexities of hosted Internet applications, high dynamics in workloads and the shared virtualized infrastructure. Obtaining a model among VM capacity, server configuration, performance and power consumption is a very hard problem even for just one...
Server parameter tuning in virtualized data centers is crucial to performance and availability of hosted Internet applications. It is challenging due to high dynamics and burstiness of workloads, multi-tier service architecture, and virtualized server infrastructure. In this paper, we investigate automated and agile server parameter tuning for maximizing effective throughput of multi-tier Internet...
