The training provided the participants with the overview of the grid network, the architecture of the gLite middleware, an introduction to job submission, data management and grid workflows, the concept of virtual organizations and the virtual organisation management system, as well as practical exercises on the use of gLite on the GILDA testbed.
To process the MRI data, a computer overlaid on Pickens' brain a virtual three-dimensional grid of 50, 000 cubes called voxels (a word hinting at volume and pixels).
Mr Wladawsky-Berger's hospital would similarly crunch patient-data using the internet, or grid, as if it were a single, giant virtual microprocessor, but for a more earth-bound purpose.
