This paper reports our experience implementing the Blizzard fine-grain distributed shared memory system on a network of unmodified dual-processor workstations running a commercial operating system. The paper describes and measures: three fine-grain access control mechanisms (optimized software, commodity hardware , and custom hardware); a low-latency,(More)
Architectural simulators are essential tools for computer architecture and systems research and development. Simulators, however, are becoming frustratingly slow, because they must now model increasingly complex micro-architectures running realistic workloads. Previously, we developed a technique called fast-forwarding, which applied partial evaluation and(More)
