Heterogeneous Computation Migration on LLVM

In past decades, the development of mobile applications was limited due to lack of enough computational power. To resolve this problem, the framework of mobile cloud computing (MCC) was proposed for offloading the massive computation tasks of mobile applications onto cloud centers for execution. However, the computational power of mobile devices recently has received a great promotion, and the bandwidth and reliability of wireless networks has been significantly improved. These development advances make it practical for mobile devices to share the computational tasks of cloud centers. In other words, the direction of resource supply chain can be from clouds to mobile devices but also from mobile devices to clouds. This is useful for integrating the computational power of mobile devices and cloud resources to serve mobile or cloud users. To achieve this goal, this paper is aimed at the development of an efficient scheme of computation migration based on LLVM for addressing the problem of resource heterogeneity and dynamicity in MCC. With the support of the proposed scheme, user programs can dynamically move between mobile devices and cloud servers for the load balance, QoS and reliability of MCC.
