Implementations of area under the curve

  • Serial
  • OpenMP (shared)
  • MPI (message passing)
  • MPI (hybrid mp and shared)
  • OpenMP + MPI (hybrid)

GalaxSee Goals

  • Good piece of code, serves as teaching example for n-body problems in petascale.
  • Dials, knobs, etc. in place to easily control how work is distributed when running in parallel.
  • Architecture generally supports hybrid model running on large-scale constellations.
  • Produces runtime data that enables nice comparisons across multiple resources (scaling, speedup, efficiency).
  • Render in BCCD, metaverse, and /dev/null environments.
  • Serial version
  • Improve performance on math?

GalaxSee - scale to petascale with MPI and OpenMP hybrid.

  • GalaxSee - render in-world and steer from in-world.
  • Area under a curve - serial, MPI, and OpenMP implementations.
  • OpenMPI - testing, performance.
  • Start May 11th

LittleFe

  • Testing
  • Documentation
  • Touch screen interface

To Do

  • Subscribe to ccg@cs.earlham.edu
  • Work on two poster abstracts
  • Work on team essay

Notes from May 21, 2009 Review

  • Combined Makefiles with defines to build on a particular platform
  • Write a driver script for GalaxSee ala the area under the curve script, consider combining
  • Schema
    • date, program_name, program_version, style, command line, compute_resource, NP, wall_time
  • Document the process from start to finish
  • Consider how we might iterate over e.g. number of stars, number of segments, etc.
  • Command line option to stat.pl that provides a Torque wrapper for the scripts.
  • Lint all code, consistent formatting
  • Install latest and greatest Intel compiler in /cluster/bobsced
