Stream processing applications continuously process large amounts of online streaming data in real-time or near real-time. They have strict latency constraints, but they are also vulnerable to failures. Failure recoveries may slow down the entire processing pipeline and break latency constraints. Upstream backup is one of the most widely applied fault-tolerant schemes for stream processing systems...
Novel virtualized HPC centers provide isolated and configurable Virtual Clusters (VC) on shared distributed infrastructures as execution environments for parallel and distributed applications. These VCs are usually customized and deployed per job in runtime. Allocating physical resources for VC is known as Virtual Cluster Mapping (VCM) problem, which is a critical issue that affects both performance...
Meta-scheduling is proven to be an essential tool for resource management in cross-domain environments like Grids. This paper takes one step further in combining meta-scheduling with application management tool to present a novel multi-domain cloud environment for biological research. With the scalable architecture and stable performance, Community Scheduler Framework (CSF) is a mature meta-scheduler...
Virtualization technology is proven to be a promising way to facilitate configurable and usable HPC environments for large-scale scientific and industrial applications. This paper focuses on enhancing the flexibility and reliability of virtual infrastructures (VI). With the rapid development of virtualization technology and the prevalence of virtual HPC platforms, it is of great significance to extend...
