To Do
- Fitz/Charlie's message
- Petascale review
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
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
