dcblogs writes: In the global race to build the next generation of supercomputers — exascale — there is no guarantee the U.S. will finish first. But the stakes are high for the U.S. tech industry. Today, U.S. firms — Hewlett-Packard, IBM and Intel, in particular — dominate the global high performance computing (HPC) market. On the Top 500 list, the worldwide ranking of the most powerful supercomputers, HP now has 39% of the systems, IBM, 33%, and Cray, nearly 10%. That lopsided U.S. marketshare does not sit well with other countries, which are busy building their own chips, interconnects and their own high-tech industries in the push for exascale. Europe and China are deep into effort to build exascale machines, and now so is Japan. Kimihiko Hirao, director of the RIKEN Advanced Institute for Computational Science of Japan, said Japan is prepping a system for 2020. Asked whether he sees the push to exascale as a race between nations, Hirao said yes. Will Japan try to win that race? "I hope so," he said. "We are rather confident," said Hirao, arguing that Japan has the technology and the people to achieve the goal. Jack Dongarra, a professor of computer science at the University of Tennessee and one of the academic leaders of the Top 500 supercomputing list, said Japan is serious and on target to deliver a system by 2020. Citing Japan's previous accomplishments in supercomputing, Dongarra said that "when the Japanese put down a plan to deliver a machine, they deliver the machine."
