Game of Life
|
This is a demonstration of Conway's Game of Life, a cellular automaton.
This 552 LOC implementation was presented at EuroPVM/MPI 2007 by Gropp
and Lusk as a tutorial on advanced MPI-2. ISP analyzes this example in seconds.
The code for this can be downloaded
here.

Madre
|
|
This is S. and A. Siegel's Memory Aware Data Redistribution Engine for
utilizing distributed memory (in clusters). ISP found a previously documented
deadlock in an improptu run at EuroPVM 2008. It detected a previously
unknown resource leak as well.
Madre's home page is located here.

ParMETIS
|
This MPI based parallel library (of 14k LOC) that implements
algorithms for working with graphs, meshes and matricies initially
took days to run to completion on ISP. Now it completes in about 5
seconds on a laptop.
You may download ParMETIS's source code
here.

MPI-Blast
|
This is an MPI port (from Los Alamos National Laboratory, and now at Virginia Tech) of the
genomic sequence database tools of BLAST (Basic Local Alignment Search
Tool). This version contains about 70,000 lines of code and utilizes
the nondeterministic MPI constructs Probe and iProbe. ISP runs to
completion with small test inputs.

SPEC Benchmarks
|
These are a suite of benchmarks made for testing MPI implementations,
called MPI2007. We experienced reasonable performance on a few of
the MPI2007 tests, but suffered state space explosion problems with the others.

website.

ADLB
|
ADLB, or Asynchronous Dynamic Load-Balancing Library is an MPI implemented
user library for performing client/server oriented load balancing. This
distribution of 8,000 lines of code is looking promising. It was written by
Rusty Lusk and others at ANL.
For more information, see Rusty's paper
here.
