In this video from the ISC 2015 conference, Erich Strohmaier from NERSC and Jack Dongarra from University of Tennessee discuss the latest HPC trends reflected in the 45th TOP500 list.
The only new entry in the Top 10 supercomputers on the latest list is at No. 7—Shaheen II is a Cray XC40 system installed at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia. Shaheen II achieved 5.536 petaflop/s on the Linpack benchmark, making it the highest-ranked Middle East system in the 22-year history of the list and the first to crack the Top 10. The other nine systems in the top 10 were all installed in 2011 or 2012, and this low level of turnover among the top supercomputers reflects a slowing trend that began in 2008.
