TotalView is an advanced 32- and 64-bit graphical debugger providing software engineers with complete control over parallel and threaded applications written in C, C++ or Fortran. Not your average debugger, TotalView also provides unique, proprietary memory debugging technology that neither instruments code nor alters libraries. TotalView's memory debugging features are fully integrated into the debugger. And, the user experience is enhanced by an on-demand, view-based approach that eliminates the need to wait for post-mortem style reports common in stand-alone memory tools.

The first installation of the IBM Blue Gene/L supercomputer system is at Lawrence Livermore National Labs (LLNL) and is the fastest computer in the world. TotalView is the tool of choice for debugging the complex code being developed there. In fact, TotalView runs on 98 of the top 100 supercomputers (see www.top500.org) in the world. Etnus, IBM, and LLNL worked closely together to create the premier ultra-scale debugging solution TotalView provides for this system and those advancements are available to all users of TotalView. Those advancements include the availability of TotalView for the IBM Linux on POWER platform, the ability to launch and digest information in an application containing thousands of processes quickly, to expose and visualize message queue information for IBM’s MPI for Blue Gene/L, and to provide a very flexible debugging environment that gives the user extreme control over the application being debugged.

"We are delighted to be working with leading solution providers like Etnus to provide our clients high-performance computing solutions that help enhance and protect the integrity of applications required to run their businesses," said DaveTurek, VP of IBM Deep Computing. "The combination of IBM and business partner innovations is helping advance the use of supercomputing power from the halls of academia and government to more commercial applications."

LLNL researchers plan to use Blue Gene/L to simulate physical phenomena that require computational capability much greater than presently available, such as cosmology and the behavior of stellar binary pairs, laser-plasma interactions, and the behavior and aging of high explosives. Not only do these applications require unheard of before computational capability, but they also are some of the most complex applications to write and understand. With the added complexity comes difficulty in debugging. TotalView eases complex code debugging with features absent in run-of-the-mill debuggers. TotalView is fast and efficient to start on codes containing even thousands of processes, and advanced features specific to debugging MPI, OpenMP, and threaded code ease the pain of finding elusive bugs.
