TotalView Previews Reverse Debugging Features for Multi-Core

TOTALVIEW TECHNOLOGIES PREVIEWS reverse debugging features for multi-core
debugging product line

New Capability to "Walk Backward Through Your Code" Further Reduces User
Frustration and Significantly Improves Productivity

Natick, MA - November 6, 2007 - TotalView Technologies, the world's leading
provider of scalable debugging and analysis software solutions for the
multi-core era, today announced that the company will be previewing reverse
debugging capabilities for its award-winning multi-core debugging product
line, including the TotalView Debugger and MemoryScape memory debugger, at
the upcoming SC '07 show as part of its early experience program for
customers. With this new capability, developers will be able to "back up"
during a debugging session to help identify a bug as it is happening,
improving the efficiency of debugging sessions by eliminating the need to
run a program multiple times.

TotalView Technologies' new reverse debugging features will allow
developers to:

* Capture and replay the exact behavior of the program from any point in
the past during a single debugging session;

* Step backward from crashes and out of functions to see what went wrong;

* Jump forward and backward to examine and compare any set of points along
the captured execution sequence;

* Replay thread context switches exactly as they happened;

* Seamlessly and clearly switch between record mode and replay mode.

"We are continually looking for new ways to further improve our multi-core
debugging products to enable our customers to increase productivity and
product quality," said Kelly Cunningham, vice president of engineering at
TotalView Technologies. "We believe the new reverse debugging capability
will provide users with even more powerful debugging capabilities, while
retaining the ease-of-use that our products are known for."

TotalView Debugger is a comprehensive source code and optional memory
debugging solution that dramatically enhances and simplifies 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 Debugger supports hybrid
applications that utilize OpenMP and MPI to make efficient use of
multi-core clusters. TotalView Debugger debugs applications built from
components that may have been written in different languages (FORTRAN 90
and C++, for example) and then compiled with different compilers (Intel and
GCC, for example) but run together as a single executable. TotalView
Debugger is robust and easy to use, with an intuitive GUI that helps users
quickly isolate and identify the root cause of problems.

MemoryScape is an easy-to-use, graphical, interactive memory debugger that
helps developers, build engineers, and QA testers identify, inspect and
resolve difficult memory problems in C, C++ and FORTRAN, including complex
multi-process and multi-threaded programs. Designed to be an integrated
part of the software development process, MemoryScape allows development
teams to watch for memory leaks and monitor memory usage while an
application is running. It enables developers to monitor heap memory, view
memory usage, locate memory leaks, track memory events and show corrupted
memory. Developers can also save and compare memory states and compile
sophisticated memory reports. MemoryScape is non-intrusive, so developers
can find memory problems without recompiling, and without waiting all day
for even the smallest test to run.

In a related announcement last week, TotalView Technologies announced an
early experience program for the new TotalView Workbench, Performance
Analysis Tools and TotalView TracePoints products. Stop by the TotalView
Technologies booth at SC '07, #124, to see a sneak preview of these
exciting new additions to the company's comprehensive suite of multi-core
debugging tools.
