Description of the performance expedition from the NCSA FY02 program plan.
Building Terascale Applications, Systems and Tools: Enhancing
Clusters. The
DTF is a first-of-its-kind facility. At one level it can be seen as a tightly
coupled resource Grid, but a closer look reveals that it is also a homogenous,
distributed computer system. Many applications will need to take advantage of
the DTF infrastructure en masse. To accomplish this, we will need to push both
system software (e.g., I/O libraries, schedulers, load balancing tools, and
scientific libraries) and application codes beyond their current limits. We
will work with community codes from the Alliance hydrology, cosmology, and
scientific instruments teams to port and tune community codes and enhance the
requisite software tools. The endeavor will include the NCSA performance
engineering group and environmental hydrology group members, ET partners Gropp
(Argonne), Taylor (Northwestern), Reed (UIUC), Kennedy (Rice), Johnsson
(Houston), Dongarra (Tennessee), Woodward (Minnesota), and Vernon (Wisconsin),
and AT partners Carey (Texas), Hernquist (Harvard), Kemball (NRAO), Norman
(UCSD), Ostriker (Princeton), and Tafti (NCSA/Virginia Tech). The specific
codes are discussed in the AT FY02 plans section. The expected DTF TeraGrid
results include:
- Demonstrated performance on scalable I/O and distributed data in the DTF
environment.
- Scalable software libraries for DTF.
- DTF codes packaged as Applications-in-a-Box released to the user
community.
- Development of programming and optimization tools derived from these test
cases suitable for broad use by the DTF user community.
