Submission + - White House warns of supercomputer arms race (computerworld.com)

dcblogs writes: The White House's science advisors, in a report last week, said a petaflop-by-petaflop race to achieve number one on the Top500 could prove costly and divert money from supercomputing research. "While it would be imprudent to allow ourselves to fall significantly behind our peers with respect to scientific performance benchmarks that have demonstrable practical significance, a single-minded focus on maintaining clear superiority in terms of flops count is probably not in our national interest," the report said. It is urging the supercomputing community to expand its benchmark measures beyong the Top500's Linpack. It says the Graph500, for data-intensive applications involving the rapid execution of graph operations, "will be more relevant," but also acknowledges that it will difficult to rely on any one measure.
