|Abstract:||In recent years, the concept of network virtualization has attracted significant attention in the debate on how to model the next-generation networking paradigm that can replace the existing Internet. Cloud computing is an emerging area that affects IT infrastructure, network services, and applications. Virtualization is a key enabler for Cloud computing. Modern computers are sufﬁciently powerful to use virtualization to present the illusion of many smaller virtual machines (VMs), each running a separate operating system instance. This has led to a resurgence of interest in VM technology.
Paravirtualizing systems expose unique and exciting opportunities to the HPC community in the form of ﬂexible system maintenance, management, and customization. Such systems however, are currently not considered for HPC environments since they are perceived to impose overhead that is unacceptable for performance-critical applications and systems. So, virtualization for HPC applications is currently limited despite its potential for both improving resource utilization as well as providing resource guarantees to its users. For virtual machines running in Xen, one of the more interesting aspects is how it addressed the issue of per-guest networking with a limited amount of physical network interface cards available. Our project is concerned with bypassing the current standard internal communication model of Xen for HPC jobs. We believe that for virtualized distributed data flow processing systems, most of the problems can be solved if TCP is replaced by SCTP in the protocol stack. This evaluation of a Xen-based prototype achieves throughput improvement for VMs which also leads to improvement in application level performance.
