"Heroic" Metacomputing in Collaboration with the Stuttgart Supercomputing Center HLRS (terminated)
Heroic Metacomputing is the ultimate limit of massively parallel computing. In heroic metacomputing we cluster a number of massively parallel supercomputers distributed worldwide to solve problems which are too large for a single supercomputer.

The opposite of 'heroic' metacomputing is the fully commercialized version named "dotcomish" metacomputing.
