Small swiss supercomputer shows the way ahead on efficiency
Lily Newman · IEEE Spectrum · 2014
Scan the latest list of the 10 most powerful supercomputers and the list of the top 10 most energy efficient and you'll see that only one name appears on both. The Piz Daint supercomputer is both the sixth most powerful machine in the world and the fourth most energy efficient. It's also one of only two supercomputers in the top 10 of the efficiency ranking (the Green500) that's capable of maintaining petaflops performance- a million billion floating-point operations per second. How it managed to make its mark in both categories could point the way to both more powerful and more efficient future machines.
