Multiscale not Multicore: Efficient Heterogeneous Cloud Computing
In this paper, authors present a vision of the future of heterogeneous cloud computing. Ours is a cleanslate approach, sweeping away decades of accreted system software. They believe the advent of the latest technology discontinuity - the move to the virtual cloud - makes this a necessary step to take, but one capable of delivering significant benefits in the security, reliability and efficiency of the digital infrastructure at all scales. Authors motivate this vision by presenting two challenges arising in different fields yet with fundamental commonalities best addressed by a unifying software platform supporting devices ranging from virtual servers in the cloud, through desktops, to mobile smartphones.
