Lawrence Livermore National Laboratory researchers have performed record simulations using all 1,572,864 cores of Sequoia, the largest supercomputer in the world.
About the photo:
OSIRIS simulation on Sequoia of the interaction of a fast-ignition-scale laser with a dense DT plasma. The laser field is shown in green, the blue arrows illustrate the magnetic field lines at the plasma interface and the red/yellow spheres are the laser-accelerated electrons that will heat and ignite the fuel.
