TotalView Technologies Adds New Features to Industry-Leading TotalView® and MemoryScape Debuggers

New TotalView® 8.3 and MemoryScape 2.1 Easier to Use for MPI Developers

NATICK, MA--(Marketwire - October 15, 2007) - TotalView Technologies, the world's leading provider of scalable debugging and analysis software solutions for the multi-core era, today introduced new versions of its advanced debugging solutions, TotalView Debugger 8.3 and MemoryScape 2.1. The products have been updated to add to their already considerable power and simplicity, with a focus on making it easier for MPI programmers to streamline their application development processes.

"The new and enhanced features in TotalView 8.3 and MemoryScape 2.1 accelerate our ability to identify where and why problems occur in our software," said Nick Monyatovsky, software engineer at SIMULIA. "MemoryScape 2.1 enabled us to identify memory issues and by using its scripting interface, we were able to automate the evaluation process. Now, the system automatically uncovers any hidden latent errors in our code with every build, allowing our developers to proactively fix potential errors prior to release."

TotalView is a comprehensive source code and optional memory debugging solution 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 supports hybrid applications that utilize OpenMP and MPI to make efficient use of multi-core clusters. TotalView 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 is also robust and easy to use, with an intuitive GUI that helps users quickly isolate and identify the root cause of problems.

New features of TotalView 8.3 include:

--  Improved MPI launch
    Enables customers to run TotalView without having to re-configure
    their MPI installation.

--  Improved data view across processes/threads
    Users can now see data across many processes or threads in a single
    operation, helping to solve MPI and thread bugs more quickly.

--  Highlight variable changes
    Seeing data change as the program executes helps identify and solve
    bugs more quickly.

--  Improved watchpoints feature
    Setting a watchpoint is simpler, making it easier to find and fix
    difficult problems in situations where the variable changes in an
    unexpected way.

--  Easier to find "expand all" in data window
    Toggling detailed vs. collapse views is quicker, allowing
    developers to more easily work with hierarchically structured data.

--  Additional new operating systems supported, including:
    --  Mac OS X 10.4.5, 10.4.8 and 10.4.9
    --  Fedora Core 7
    --  Ubuntu 1.06

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.

MemoryScape 2.1 extends the product's capabilities to now include:

--  Improved MPI launch
    Enables customers to run MemoryScape without having to reconfigure
    their MPI installation.

--  Multi-file loading
    Simplifies working with core files from parallel applications.

--  New simplified memscript output
    Makes comparison between runs easier.

--  New operating systems supported, including:
    --  Mac OS X 10.4.5, 10.4.8 and 10.4.9
    --  Fedora Core 7
    --  Ubuntu 1.06

"We designed TotalView 8.3 and MemoryScape 2.1 to provide a better debugging experience right out of the box, with new features to help our customers improve productivity and find problems easier," said Dick Andersen, vice president of marketing at TotalView Technologies. "As the user community for high-performance computing continues to grow, we are committed to providing products that address the multi-core debugging needs of all software developers, from users debugging on a laptop or single workstation to those working on the world's largest supercomputers."
