Cloudlet-screen computing: A multi-core-based, cloud-computing-oriented, traditional-computing-compatible parallel computing Paradigm for the masses

This paper proposes a computing paradigm where many users share a host platform consisting of one or more multicore CPU(s) and GPU(s). Each user is connected to the host by a link transferring primarily compressed compound video of screen, mouse and keyboard data. All computation and processing tasks including but not limited to 2D/3D graphics and multimedia processing are done on the host using a traditional or existing architecture. Since all computing and storage resources are centralized on the "cloudlet" (host) and each user site has only a high-resolution monitor, a mouse, and a keyboard with some optional I/O devices, it is a highly energy-efficient, secure, reliable, and low total-ownership-cost paradigm. The compound video link between the host and the user is partial-lossless (partially lossless and partially near-lossless), and has ultra-low latency, so the proposed paradigm still has no-compromised 2D/3D graphics and multimedia performance demanded by the mass market.
