On-Demand Virtual Cluster in Cloud WebOS with Fault Tolerance Module

As virtualization technologies become more prevalent, each Cloud user encounters the problem of building his/her own virtual cluster with less friendly interface of virtual resource management. To help resolving this issue, an On-Demand Virtual Cluster in Cloud Web-Based OS feature has been developed by the Pervasive Computing Team in the National Center for High-performance Computing (NCHC). The On-Demand Virtual Cluster system exhibits the ability to reconfigure itself to adapt to the changes in the Cloud environment. And, it can discover, diagnose, and monitor Cloud computing resources automatically. An On-Demand Virtual Cluster system embedded in the Cloud WebOS is developed. An extremely lightweight approach helps the acquisition of virtual computing services to provide dynamically creation mechanism. The approach leverages virtualization techniques combined with cluster queuing system and transparently the fault tolerance capability to the parallel HPC application.
