“…Our previous work (Lange et al, 2011b, 2010) has focused on incorporating the Palacios VMM in a lightweight kernel context, and demonstrating that virtualization can be both scalable and exhibit very low overhead. Stoess et al (2011) presented a lightweight VMM capable of virtualizing the Blue Gene/P platform running IBM’s CNK. This work had similar goals in that it sought to provide a compatibility layer to run more standard OSs on top of a LWK architecture.…”

Modified variants of Linux are likely to be the underlying operating systems (OSs) for future exascale platforms. Despite the many advantages of this approach, a subset of applications exist in which a lightweight kernel (LWK)-based OS is needed and/or preferred. We contend that virtualization is capable of supporting LWKs as virtual machines (VMs) running at scale on top of a Linux environment. Furthermore, we claim that a properly designed virtual machine monitor (VMM) can provide an isolated and independent environment that avoids the overheads of the Linux host OS. To validate the feasibility of this approach we demonstrate that given a Linux host OS, benchmarks running in a virtualized LWK environment are capable of outperforming the same benchmarks executed directly on the Linux host.

“…Modern cloud interconnects increasingly focus on high bandwidth and low latency on the one hand, and balanced design and power awareness on the other: HPC network fabrics such as InfiniBand or Blue Gene are being investigated in cloud computing setups [3]- [6]; their underlying technologies such as user-level I/O and remote DMA are gaining momentum also for commodity Ethernet networks [7]. Research is also investigating power-efficient network alternatives such as PCIe for their suitability as inter-node fabric [8].…”

Abstract-In this paper, we present early experiences with libRIPC, a light-weight communication library for highperformance cloud networks. Coming cloud networks are expected to be tightly interconnected and to show capabilities formerly reserved to high-performance computing. LibRIPC aims to bring the benefits of such architectures to heterogeneous cloud workloads.LibRIPC was designed for low footprint and easy integration; it supports reconfiguration and mutually untrusted communication partners. LibRIPC offers short and long transmit primitives, which are optimized for control messages and bulk data transfer respectively. Early experiments with a Java-based web server indicate that libRIPC integrates well into typical cloud workloads and brings substantial speedup of at least a factor of three for larger data transfers compared to socket-based TCP/IP communication.
