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
