Etnus TotalView for US DOE's 30 Tflop/s systemFramingham 02 October 2000 Etnus' TotalView debugger/analyzer was selected for use in the U.S. Department of Energy's (DOE) National Nuclear Security Administrations (NNSA) 30 tflop/s supercomputer to be built by Compaq.
The Q-supercomputer the next planned addition to the
Accelerated Strategic Computing Initiative (ASCI) within NNSA's
Stockpile Stewardship Program, which uses an integrated program of
surveillance, experiments, non-nuclear tests, archived data, modeling
and simulation to assess and certify the safety, security and
reliability of nuclear weapons without underground nuclear testing.
Since 1997, TotalView has been used by ASCI in their
multi-thousand processor systems.
Able to scale beyond the capabilities of any other debugger and
run on all major platforms, Total View is used to debug applications
that range from modeling nuclear interactions to simulating oil
reservoirs, executing sophisticated econometric analysis, and creating
leading edge internet applications.
"Terascale compute platforms are in themselves not sufficient to
meet the needs of the DOE ASCI program. Complex application codes must
be developed, debugged, tuned, and executed with high performance at a
scale never before attempted," explains Jeff Brown, Problem Solving
Environment Project Leader with the DOE Los Alamos National
Laboratory. "The TotalView debugger has become an indispensable code
development tool for developing complex code needing for ASCI
projects."
TotalView is a multiprocess, multithread application
debugger/analyzer that supports Fortran, C and C++ languages along
with the major parallel programming paradigms including MPI, threads,
and OpenMP. GUI-based, it shortens development time via an
easy-to-learn and easy-to-use "select-and-dive" approach. It enables
developers to unravel and control multiple threads and processes
running on single or multiple processor systems.
