**Department of Energy Laboratories, Researchers to Showcase**

**High Performance Computing Expertise at SC07 Conference**

Throughout the course of the four-day SC07 technical program,
DOE-supported researchers will have a role in:

-   18 of the 54 peer-reviewed technical papers

-   5 of the 7 panel discussions

-   10 of the 25 tutorial sessions

-   6 of the 10 workshops

-   2 of the 15 invited "Masterworks" talks

-   13 of the 45 research posters

The SC conference also sponsors a series of competitive computing
activities, in which DOE-supported researchers are among the finalists.

For the Gordon Bell Prize, given annually to recognize outstanding
achievement in computing performance, two of the four finalist teams
include DOE scientists.

In the Analytics Challenge, which highlights the analysis and
visualization of massive data sets, one of the two finalist teams
includes DOE researchers.

In the Storage Challenge, which showcases effective approaches using
storage subsystems of high performance computing systems, two of the
four finalists include DOE members.

In the Bandwidth Challenge, which emphasizes moving large amounts of
data across networks, one of the seven finalist teams includes DOE
researchers.

Additionally, many of DOE's national laboratories will display their
computational science achievements, as will a number of universities
with DOE research partnerships.

SC07, the international conference on high performance computing,
networking, storage and analysis, is chaired by Becky Verastegui,
Director of the Information Technology Services Division at Oak Ridge
National Laboratory.
