Abstract or Table of Contents

This paper presents the architecture and motivation for a cluster based, many-core computing architecture for energy-efficient, data intensive computing. FAWN, a Fast Array of Wimpy Nodes, consists of a large number of slower but efficient nodes coupled with low-power storage. We present the computing trends that motivate a FAWN-like approach, for CPU, memory, and storage. We follow with a set of micro benchmarks to explore under what workloads these “wimpy nodes” perform well (or perform poorly). We conclude with an outline of the longer-term implications of FAWN that lead us to select a tightly integrated stacked chip-and-memory architecture for future FAWN development
