"With TotalView (Debugger) available on Solaris 10 for both SPARC and Opteron, developers now have a common development platform with a best-of-breed parallel debugger to identify challenging source code and memory problems. TotalView users that are new to the Solaris environment don't have to spend time learning to use a different debugger, making the Solaris platform even more accessible."

Bjorn Andersson: Director of HPC Marketing, Sun Microsystems, Inc.

"We used to use print statements to debug our code. Since switching to TotalView (Debugger), we have reduced debugging time by about 20%, and expect this figure to grow to 40% as we increase our use of TotalView for parallel programs using MPI and Open MP. The built-in memory debugger has been key to optimizing memory use in our multi-processor applications. Even better, TotalView gives us the flexibility to use the same tool on a variety of platforms. Bottom line, TotalView is an essential tool in our application development."

Mats Carlsson: Professor of Astrophysics , University of Oslo

"With regard to the TotalView Debugger, there was no Plan B. University of Missouri - St. Louis could not find a tool that came close to the power and simplicity of the TotalView Debugger in a multi-process/thread environment."

Jerrold Siegel, Research Professor of Mathematics and Computer Science, University of Missouri - St. Louis

"TotalView has proven to be a valuable tool for debugging our data-intensive reservoir modeling and simulation software. It helps us find bugs fast, so we can get our products to market sooner."

Birgir Sigurjonsson: Principal Software Engineer, Roxar AS, Stavenger, Norway

"The memory debugger within TotalView is amazing. It's much easier to use than Valgrind, and produces results much faster. In addition, the C/C++ debugger is more stable than gdb and provides a much more intuitive interface."

Tim Blechmann: University Student , Computer Music & Computer Science, Vienna, Austria

"Our AMR application involves dynamic memory consumption that, under extreme runtime conditions, can cause the application to perform very slowly or crash altogether. TotalView enables us to detect and avoid these problems by monitoring memory usage at specified key stages in the application. In addition, it helps us understand differences in memory consumption when identical application sources and baseline conditions are run on different platforms."

Sharon Brunett: Senior Scientiest, California Institute of Technology

"We rely on TotalView for all of our parallel debugging needs. Its scalability, multi-language support and built-in interactive memory debugger make it an indispensable tool for us."

David Gunter: Parallel Tools Team, Los Alamos National Laboratory

"TotalView gives us unique insight into our code. It's the only debugger we have used that consistently shows backtraces and the information in each code frame. It also allows me to drill down and graph information on the fly. TotalView makes debugging 25-50% easier."

Charles Finan: Managing Director, Bear Stearns & Company

"For fifteen years, I have relied on TotalView to debug massively parallel code (200,000 lines of Fortran) on a variety of machines and platforms at various national labs. It's the only product out there that's robust enough to meet the challenge. The integrated memory debugger can reduce a week's worth of debugging time to less than a half day."

Carol Hoover: Research Scientist

"The TotalView memory debugger is great. It is the only tool I have used that is able to find memory leaks in complex C++ programs. I had a recent case in which standard debugging techniques, including print statements, failed to identify an elusive "memory overflow" problem. The leak detection feature in the TotalView memory debugger pointed straight to the line of source code that created the problem, showing exactly which call was generating the stale pointers. After I corrected the bug, the heap status feature in the TotalView memory debugger indicated that there were no other memory leaks. On rerunning the program, the problem was gone. I am a TotalView believer!"

JoAnne Levatin: Programmer, San Francisco Bay Area

"TotalView is great for debugging global arrays, which are common in our computational chemistry applications. The product was incredibly easy to set up and use".

Andy Young: Research Associate, Johns Hopkins University

"Our advanced finite element analysis software has a large volume of code, shared libraries, and uses a variety of techniques for distributed memory and parallel execution--all characteristics that require diligent quality checks. Additionally, we also use multiple programming languages and support multiple computing platforms, which add to our quality control requirements. Total View has the power and flexibility to address these challenges and more. The software assists in making our quality checks more efficient and productive, which reduces our time-to-market."
