Natick, MA - December 17, 2007 - TotalView Technologies, the world’s leading provider of scalable debugging and analysis software solutions for the multi-core era, today announced that SGI (NASDAQ: SGIC), a leader in high-performance computing, will make TotalView Technologies’ award-winning debugging product line available to its customers. SGI will resell all TotalView Technologies software products, including the TotalView® and MemoryScape debuggers.

SGI delivers a broad range of high-performance server, visualization and storage solutions, along with industry-leading professional services and support, to enable its customers to overcome the challenges involved with complex data-intensive workflows. SGI customers are responsible for creating a variety of advanced computing applications, including work with life-saving medicines, new generations of space exploration vehicles, groundbreaking climate change studies, Academy Award®-winning special effects, new sustainable forms of energy and weapons, and intelligence technologies that are vital to United States security.

“TotalView Technologies offers best-of-breed debugging solutions that scale to meet the complexity of today’s applications,” said Bill Mannel, director of server marketing at SGI. “We believe that by working with them to address the growing needs of the high-performance computing market, we can deliver the products and services that help developers boost productivity and product quality.”

TotalView, a comprehensive source code and optional memory debugging solution, is the most advanced debugger for UNIX, Linux, and Mac OS X and is the market leader in parallel programming techniques used in multi-core environments such as threads, MPI, and OpenMP written in C/C++, FORTRAN and UPC. TotalView dramatically enhances developer productivity by simplifying the process of debugging data-intensive, multi-process, multi-threaded, or network-distributed applications. Built to handle the complexities of the world’s most demanding applications, TotalView is robust and easy to use, with an intuitive GUI that helps users quickly isolate and identify the root cause of problems.

MemoryScape is a 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 enables developers to monitor heap memory, view memory usage, locate memory leaks, track memory events and show corrupted memory, while an application is running. 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.

“SGI has been a recognized leader in the high-performance computing market for over 25 years, and the addition of our multi-core debugging product line will help them offer an even better solution to their customers,” said Jim Chafel, vice president of business development at TotalView Technologies. “We are honored to be working with SGI and we believe that this relationship is a testament to the quality and sheer power of our products.”
