GridLab is one of the biggest European research projects for the development of application tools and middleware for Grid environments, and will include capabilities such as dynamic resource brokering, monitoring, data management, security, information, and adaptive services. GridLab technologies are being tested with Cactus (a framework for scientific numerical simulations) and Triana (a visual workflow-oriented data analysis environment). At iGrid, a Cactus application runs a large-scale black-hole simulation at one site and writes the data to local discs, and then transfers all the data to be post processed and visualized to another site. In the meantime, the application checkpoints and migrates the computation to another machine, possibly several times due to external events such as system performance is decreasing or a machine is going to be shutdown. Every application migration requires a transfer of several gigabytes of checkpoint data, together with the output data for visualization. The European Commission under the 5th Framework Programme funds GridLab.
