GridLab
A project funded by the European Commission
The project was started in January 2002
Software releases should ready in December 2004

GAT- The Grid Application Toolkit
To goal of the project is to develop a Grid Application Toolkit (GAT)
GAT should be flexible, easy to use, generic and modular
GAT enables applications of today to use the global computing resources in an innovative way

Work Packages
12 core packages
Also 3 additional packages which cover exploitation, dissemination and project management

Software
The project will provide the following software components: Grid Application Toolkit a set of Grid services Portal Development Framework
GridSphere and a set of GridSphere Portlets
Most of GridLab software is being distributed with Open Source licences

User scenario
Gravitational wave detection analysis With the help of GridLab, the researchers
can choose suitable machines for computing
The portal notifies the researchers of machine overloads (for example as an SMS message)
The user can connect to the portal (for example by using a PDA) and change machines used for the computation

Collaborations
N*Grid A project to build a Grid infrastructure
across South Korea
GriKSL A German project Uses the same TestBed than GridLab

Cactus
open source problem solving environment designed for scientists and engineers
designed by Paul Walker, Joan Masso, John Shalf and Ed Seidel as a code for numerical relativity
Since the cactuscode is free, it has been adapted to many platforms and systems.

Cactus
The project aims at providing an open source High Performance Computing framework that allows the scientific community to immediately benefit from the advances in IT technology.

Cactus Architecture
Cactus comprises of the core code (“the Flesh”) and modules (“the Thorns”).
Only these modules are visible to the user, so the underlying technology can be replaced at any time.
