Technical and economic changes in the semiconductor industry threaten to stifle U.S. development of the next generation of high-performance computers, warns a new report from the National Research Council.
With Moore's Law and the scaling of transistors waning, the industry is turning to chip designs that don't work for the supercomputing that's used in massive simulations. The report focuses on defense use in modeling the physics of nuclear weapons, but the changes also would affect simulations including those used for climate modeling and weather forecasting.
The National Nuclear Security Administration, responsible for the U.S. nuclear stockpile, "needs to fundamentally rethink its advanced computing research, engineering, acquisition, deployment, and partnership strategy," warns the report.
