PowerTracer: Tracing requests in multi-tier services to save cluster power consumption
Lin Yuan, Jianfeng Zhan, Bo Sang +2
As energy proportional computing gradually extends the success of DVFS (Dynamic voltage and frequency scaling) to the entire system, DVFS control algorithms will play a key role in…
PhoenixCloud: Provisioning Resources for Heterogeneous Workloads in Cloud Computing
Jianfeng Zhan, Lei Wang, Weisong Shi +2
As more and more service providers choose Cloud platforms, which is provided by third party resource providers, resource providers needs to provision resources for heterogeneous wo…
Scalable Group Management in Large-Scale Virtualized Clusters
Wei Zhou, Lei Wang, Dan Meng +2
To save cost, recently more and more users choose to provision virtual machine resources in cluster systems, especially in data centres. Maintaining a consistent member view is the…
In Cloud, Can Scientific Communities Benefit from the Economies of Scale?
Lei Wang, Jianfeng Zhan, Weisong Shi +1
The basic idea behind Cloud computing is that resource providers offer elastic resources to end users. In this paper, we intend to answer one key question to the success of Cloud c…
PhoenixCloud: Provisioning Resources for Heterogeneous Cloud Workloads
Jianfeng Zhan, Lei Wang, Weisong Shi +2
As more and more service providers choose Cloud platforms, a resource provider needs to provision resources and supporting runtime environments (REs) for heterogeneous workloads in…
Decreasing log data of multi-tier services for effective request tracing
Bo Sang, Jianfeng Zhan, Guanhua Tian
Previous work shows request tracing systems help understand and debug the performance problems of multi-tier services. However, for large-scale data centers, more than hundreds of…
Precise Request Tracing and Performance Debugging for Multi-tier Services of Black Boxes
Zhihong Zhang, Jianfeng Zhan, Yong Li +3
As more and more multi-tier services are developed from commercial components or heterogeneous middleware without the source code available, both developers and administrators need…
In Cloud, Do MTC or HTC Service Providers Benefit from the Economies of Scale?
Lei Wang, Jianfeng Zhan, Weisong Shi +2
In this paper, we intend to answer one key question to the success of cloud computing: in cloud, do many task computing (MTC) or high throughput computing (HTC) service providers,…
Automatic Performance Debugging of SPMD Parallel Programs
Xu Liu, Lin Yuan, Jianfeng Zhan +2
Automatic performance debugging of parallel applications usually involves two steps: automatic detection of performance bottlenecks and uncovering their root causes for performance…
