"Japan's K computer made headlines in June 2011 as the world's fastest
supercomputer and again last November when it became the first
computer to top 10 petaflops—or 10 quadrillion calculations per
second—solving a benchmark mathematical problem. (...) And now, after
a year of testing and software development, as the $1.4 billion K
computer is put to work on real-world problems, some scientific users
say it was too narrowly built for speed."

Interesting claim. What kind of architecture structure would benefit
Linpack and would hinder real-world applications?

Cheers
