This is a virtual metacomputer
whose individual processors are widely distributed clusters and whose mass storage systems are large distributed repositories of scientific data fed by scientific instruments in close to real time.
In a sense, each national supercomputing center already acts as a metacomputer
, invisibly shuffling programs and files from supercomputer to massively parallel machine to graphics computer to mass-storage device to workstation.
will empower users by providing transparent access to a variety of heterogeneous computing systems -- such as large vector multiprocessors, MPP systems or clusters -- along with data/file service, sharing the same binary data sets, and visualization tools," said Wallach.
