Million-core simulation

ibm-bluegeneResearchers at the Center for Turbulence Research set a new record in supercomputing, harnessing a million computing cores to model supersonic jet noise. Work was performed on the newly installed Sequoia IBM Bluegene/Q system at Lawrence Livermore National Laboratories, number 2 in the current Top500 list.

Joseph Nichols, a research associate in the center, worked on the newly installed Sequoia IBM Bluegene/Q system at Lawrence Livermore National Laboratories (LLNL) funded by the Advanced Simulation and Computing (ASC) Program of the National Nuclear Security Administration (NNSA). Sequoia once topped list of the world’s most powerful supercomputers, boasting 1,572,864 compute cores (processors) and 1.6 petabytes of memory connected by a high-speed five-dimensional torus interconnect.

Because of Sequoia’s impressive numbers of cores, Nichols was able to show for the first time that million-core fluid dynamics simulations are possible—and also to contribute to research aimed at designing quieter aircraft engines.
