Lawrence Livermore Selects TotalView Debugger for 20 Petaflop System

NATICK, MA--(Marketwire - August 18, 2009) - TotalView Technologies, a provider of
interactive analysis and debugging tools for serial and large scale
parallel codes, has announced that the National Nuclear Security
Administration's Lawrence Livermore National Laboratory (LLNL) has selected
the TotalView debugger to support advanced scalable code development
efforts on their Advanced Simulation and Computing (ASC) Sequoia effort.

The Sequoia effort includes two generations of IBM Blue Gene supercomputers
that will deliver the next generation of advanced systems to weapon
simulation codes being developed under the ASC program. ASC is a
cornerstone of the National Nuclear Security Administration's (NNSA)
program to ensure the safety, security and reliability of the nation's
nuclear deterrent without underground testing -- Stockpile Stewardship.
These two Blue Gene systems are "Dawn," a 500-teraflop system that was
accepted by LLNL in March of 2009, and "Sequoia," a 20-petaflop system
based on future Blue Gene technology, slated for delivery in 2011. "As a
long time IBM Business Partner, TotalView Technologies has extensive
experience with their software on IBM Blue Gene systems," said David Turek,
vice president, IBM Deep Computing. "This combined technology will prove to
be beneficial to Lawrence Livermore National Lab as we prepare to deliver
the record-breaking 20-petaflop IBM Sequoia supercomputer."

"TotalView Technologies will be continuing an ongoing relationship with
LLNL with this opportunity to collaborate on advanced debugging features,
particularly in the areas of productivity and scalability," said Rich
Collier, President and CEO at TotalView Technologies. "We are working to
provide the ASC Tri-Laboratory code developers debugging tools on both Dawn
and Sequoia with unsurpassed ease-of-use, reliability, and productivity at
high scale."

Among the features that TotalView Technologies will incorporate for the
Dawn and Sequoia systems are user-programmable data display, fast
conditional breakpoints and watchpoints, compiled expressions, asynchronous
thread control, and full post-mortem debugging.

At 20 petaflops, Sequoia will be 34 times as powerful as LLNL's current
Blue Gene/L, giving scientists a lot more computing cycles for weapons
simulations and basic science research. "Sequoia represents a major
challenge to code developers as the multi-core era demands that we
effectively absorb more cores and threads per MPI task," said Mark Seager,
Asst. Dept. Head for Advanced Computing Technology at LLNL. "This
programming challenge can only be overcome with world class code
development tools. Through our long-term partnership with cutting-edge
technology companies like TotalView Technologies we're confident we can
deliver on our demanding debugger scalability and usability requirements."

Lawrence Livermore is a NNSA national security laboratory. NNSA is a
semi-autonomous agency within the U.S. Department of Energy (DOE).

TotalView is a comprehensive source code analysis and memory error
detection tool that dramatically enhances developer productivity by
simplifying the process of debugging parallel, data-intensive,
multi-process, multi-threaded or network-distributed applications. Built to
handle the complexities of the world's most demanding applications,
TotalView offers a number of advanced features that help speed development
and eliminate bugs quickly, and is capable of scaling to thousands of
processes or threads with applications distributed over multiple machines
or processors.
