Presented at the 6th USENIX Workshop on Hot Topics in Cloud Computing (HotCloud '14), June 17-18, 2014, Philadelphia, PA.http://nrs.harvard.edu/urn-3:HUL.InstRepos:12965652Mobile device hardware can limit the sophistication of mobile applications. One strategy for side-stepping these constraints is to opportunistically offload computations to the cloud, where more capable hardware can do the heavy lifting. We propose a platform that accomplishes this via compressive offloading, a novel application of compressive sensing in a distributed shared memory setting. Our prototype gives up to an order-of-magnitude acceleration and 60% longer battery life to the end user of an example handwriting recognition app. We argue that offloading is beneficial to both end users and cloud providers—the former experiences a performance boost and the latter receives a steady stream of small computations to fill periods of under-utilization. Such workloads, originating from ARM-based mobile devices, are especially well-suited for offloading to emerging ARM-based data centers.en-USConference Paper2014-09-05Lin C-K, Kung HT2014-09-30
