Grid technology is widely emerging. Still, there is an eminent shortage of real Grid users, mostly due to the lack of a âcritical massâ of widely deployed and reliable higher-level Grid services, tailored to application needs. The GridLab project aims to provide fundamentally new capabilities for applications to exploit the power of Grid computing, thus bridging the gap between application needs and existing Grid middleware. We present an overview of GridLab, a large-scale, EU-funded Grid project spanning over a dozen groups in Europe and the US. We first outline our vision of Grid-empowered applications and then discuss GridLab's general architecture and its Grid Application Toolkit GAT. We illustrate how applications can be Grid-enabled with the GAT and discuss GridLab's scheduler as an example of GAT services.
