Abstract.
Grid and Cloud computing are well known topics, and currently one of the focus of many research and commercial projects. Nevertheless, the transparent access to Grid facilities from mobile devices (like PDAs or smartphones) is normally out of the scope of those initiatives, taking into account the intrinsic limitations of such devices: screen size and resolution, storage capacity, computational power, etc. To provide an integrated solution for mobile access to Grid computing, aspects like Virtual Organizations (VOs) support, graphical job management, exible authentication and access to the _le system user's volume in the Grid from a mobile device should be covered. That is the purpose of XtreemOS-MD, the mobile avour of XtreemOS - a Linux-based operating system to support VOs for Grids -, the transparent access to Grid facilities from mobile devices. Key words: grid, cloud computing, mobile device
1 Introduction
The Grid [10], as a distributed computational system that allows sharing non- centralized resources to solve a single problem requiring a very signi_cant com- putational power or storage capacity, is a relatively old and well known concept. Grid systems have been used specially to solve complex scienti_c and technical problems [17]. Middleware solutions like the Globus toolkit [9], the most ex- tended solution, or others like Condor [26], Legion [15] or UNICORE [7], have classically been used to implement the Grid architectures. But those solutions are designed as a \sum of services" infrastructure, where tools are developed inde- pendently [12][13][14], and the lack of common programming interfaces or uni_ed models of component interaction can impact negatively in the user-friendliness. The _nal consequence is that a certain level of experience and technology knowl- edge is required to e_ectively use the Grid. Precisely, XtreemOS [29] was designed to become a new Grid operating system allowing transparent and native access to the Grid environment, and then simplifying in big manner the use of Grid systems.
