VM-based slack emulation of large-scale systems
This paper describes the design of a system to enable large-scale testing of new software stacks and prospective high-end computing architectures. The proposed architecture combines system virtualization, time dilation, architectural simulation, and slack simulation to provide scalable emulation of hypothetical systems. We also describe virtualization-based full-system measurement and monitoring tools to aid in using the proposed system for co-design of high-performance computing system software and architectural features for future systems. Finally, we provide a description of the implementation strategy and status of the proposed system. © 2011 ACM.
