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
