“Our belief is that trying to build a quantum machine by controlling electron spin and using surface codes is like trying to build a computer using vacuum tubes. Labs all over the world can do that, but you’ll never be able to scale up.”
In this video, Jack Dongarra, Erich Strohmaier, and Michael Resch discuss the current TOP500 list at ISC’14. “Although the United States remains the top country in terms of overall systems with 233, this is down from 265 on the November 2013 list. The number of Chinese systems on the list rose from 63 to 76, giving the Asian nation nearly as many supercomputers as the UK, with 30; France, with 27; and Germany, with 23; combined. Japan also increased its showing, up to 30 from 28 on the previous list.”
In this video from the Exascale Computing in Astrophysics Conference, Tom Quinn from the University of Washington presents: Pathways to Exascale N-body Simulations.
This week Nvidia salutes Women who use CUDA for incredible science and engineering. They’ve compiled 30 profiles so far, and the advice they share from their experiences is quite inspiring. “It’s a good way to remind people that women write code, participate in open-source projects, and invent things,” said Lorena Barba from George Washington University. “It’s important to make the technology world more attractive to female students and show them examples of women who are innovators.”
Over at Typhoon Computing, Michel Müller writes programmers looking to port their code to accelerators now have a new tool called Hybrid Fortran. “This python-based preprocessor parses annotations together with your Fortran code structure, declarations, accessors and procedure calls, and then writes separate versions of your code – once for CPU with OpenMP parallelization and once for GPU with CUDA Fortran.”
Over at the Data Stack, Mike Bernhardt has posted an interview with Georg Hager, who lead Team Germany to victory in the Intel Parallel Universe Computing Challenge at SC13. People are interested in performance, that’s why they attend SC (mostly). But there is such little competition outside the academic peer review that an idea such as […]
