Nvidia says the new
generation is greener too, with the K20X said to deliver three times
higher energy efficiency than the previous-generation.
Tesla K20X accelerators, Oak Ridge’s Titan achieved 2,142.77 megaflops
of performance per watt, which surpasses the energy efficiency of the
No. 1 system on the most recent Green500 list of the world’s most
“We really improved the
architectural efficiency,” said Gupta. He called beating IBM’s Blue Gene
Q system in energy efficiency a "big deal.”
Customers seem to be
buying into the hype, too. At launch, Nvidia could already boast
Clemson University, Indiana University, Thomas Jefferson National
Accelerator Facility (Jefferson Lab), King Abdullah University of
Science and Technology (KAUST), National Center for Supercomputing
Applications (NCSA), National Oceanic and Atmospheric Administration
(NOAA), Oak Ridge National Laboratory (ORNL), University of Southern
California (USC), and Shanghai Jiao Tong University (SJTU) as being
amongst the takers.
The new Tesla’s are shipping as of today from
manufacturers including Appro, ASUS, Cray, Eurotech, Fujitsu, HP, IBM,
Quanta Computer, SGI, Supermicro, T-Platforms and Tyan.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
