CloneCloud: Boosting Mobile Device Applications Through Cloud Clone Execution

摘要

Mobile applications are becoming increasingly ubiquitous and provide everricher functionality on mobile devices. At the same time, such devices oftenenjoy strong connectivity with more powerful machines ranging from laptops anddesktops to commercial clouds. This paper presents the design andimplementation of CloneCloud, a system that automatically transforms mobileapplications to benefit from the cloud. The system is a flexible applicationpartitioner and execution runtime that enables unmodified mobile applicationsrunning in an application-level virtual machine to seamlessly off-load part oftheir execution from mobile devices onto device clones operating in acomputational cloud. CloneCloud uses a combination of static analysis anddynamic profiling to optimally and automatically partition an application sothat it migrates, executes in the cloud, and re-integrates computation in afine-grained manner that makes efficient use of resources. Our evaluation showsthat CloneCloud can achieve up to 21.2x speedup of smartphone applications wetested and it allows different partitioning for different inputs and networks.
