A PDA client for the computational Grid

Abstract

SUMMARYAccess to the computational Grid is restricted to the laptop and desktop environment since Grid client development has been concentrated in this area. This paper presents the design and implementation of a new, lightweight computational Grid client that provides the same level of functionality and security as its desktop counterparts whilst conforming to the limitations and restrictions of a Personal Digital Assistant environment. A solution has been achieved by taking an architectural perspective of the problem and choosing a tiered, asymmetrical Grid middleware providing an asynchronous messaging model with uniform interface to all resources. The client opens up a new area of Grid computing access: secure and flexible job submission and monitoring to dependable, persistent, powerful and consistent computing services provided by a computational Grid has been freed from static environments into the mobile domain. This has been done without the modification of the underlying Grid middleware and using standards-based protocols and components: J2ME, X.509 certificates, Secure Socket Layer connections and IEEE 802.11b wireless networking.

Bringing simulation to engineers in the field: a Web 2.0 approach

“…The problem of using lightweight devices to present the results of large simulations has received attention from the e-Science community (e.g. Holmes & Kawalsky 2006;Parkin & Brooke 2007). The former work used the three tier architecture of UNICORE and the latter used Microsoft .NET services.…”
