oh yeah, the white rose grid... :)

Looks like a ball ache compared to SGE tho... And who uses GUIs these days? :)

Birmingham Uni have a similar facility that at least all researchers can access to perform large scale computation.  Having access to such a resource really broadens horizons with respect to the scale of experimentation that can be done.
