To Jonathan Cohen, Dr. Jerry Tessendorf,

  • Dr. Jeroen Molemaker and Michael

Kowalski for the development of the system

  • f fluid dynamics tools at Rhythm and Hues.

This system allows artists to create realistic animation of liquids and gases, using novel simulation techniques for accuracy and speed, as well as a unique scripting language for working with volumetric data.

SLIDE 3
  • Efficient random path perturbation that satisfies

boundary conditions & constraints.

  • Generates 1000’s of paths from an initial path.
  • Rate: ~60,000 paths/min on one core
  • To compute the radiance, a total of O(109) paths

needed for convergence.

  • Single experiment takes 80 compute years!
  • An embarrassingly parallel problem
  • Can take advantage of high throughput computing and GPU

Palmetto Cluster

  • 100 Running jobs per

dataset

  • Walltime: 72 Hours
  • Memory: 2 GB/Node
  • Manually restart

terminated/failed jobs

  • Time to Completion:

~2 weeks

  • 1,000 to 5,000 Running jobs per dataset
  • Walltime: Less than 12 hours ideal
  • Memory: 2 GB/Node
  • Input transferred to remote node

storage for computation

  • Pegasus Workflow Manager:
  • Monitors job completion
  • Failed jobs automatically restarted
  • Output stored on scratch directory

until workflow is complete

  • Time to Completion: ~24 Hours
