Among the most common solutions are the usage of grid portals or grid gateways to translate grid requests from their native form to more efficient and mobile-friendly ad-hoc protocols. In the XtreemOS project, however, a different approach has been proposed, taking advantage of the latest advances in mobile device capacities and leveraging the scalability and transparency features of XtreemOS, like native VO support, usage of POSIX standards or scalable and highly available services. With this approach, the mobile devices using XtreemOS " speak the same language " as any other grid node, transforming them into first class consumers of grid resources. This also is a much more scalable solution and opens the door to new, grid-transparent use cases that could appeal to the mass market. In XtreemOS-MD, this goal of universally accessible grid services is achieved through two different software layers: a foundation layer that enriches the operating system with virtual organization support, and a grid services layer which implements the grid services themselves. This document describes the design of a first, basic version of XtreemOS grid services (XtreemOS-G) layer, designed for PDAs. This layer contains the necessary functionality for accessing grid files and launching and managing grid jobs in a secure manner, as well as the necessary interfaces for …
