Presentation Transcript

PetascaleNanoelectronic Device SimulationsMathieu Luisier SC10 @ ORNL

Objective:

  • Physics-based simulations of nanoelectronic devices with an atomistic resolution and a sustained performance > 1 Pflop/s

  • Approach:

  • Multi-Level parallelism

  • Dynamic load balancing in double integral

  • Computational interleaving

  • Development of new direct solver (block cyclic reduction)

  • Result:

  • Highly efficient parallel algorithm, stressing the most advanced resources available today

  • Impact:

  • Move from nano-science to nanodevice engineering in minutes

  • Unprecedented insight into atomistic device simulation

  • One of the few codes with sustained performances at the peta-scale on Jaguar @ ORNL
