Grid computing is turning from promise into reality. Naturally, however, this is not happening
for all applications at once. Bag-of-tasks (BoT) applications (those parallel applications
whose tasks are independent) are, due to their simplicity, the first class of applications to be
massively executed on grids (eg SETI@ home). BoT applications are especially amendable
for grid execution because they can run on intermittent resources (ie resources with no
guarantees on availability or reliability). In this scenario, good performance and reliable …
