This article reports on the launching by Etnus, a provider of an advanced debugger on Linux and UNIX, of the TotalView debugger for the IBM Blue Gene/L supercomputer system. 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. 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. 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 Laboratory (LLNL) in the U.S. and is the fastest computer in the world. TotalView is the tool of choice for debugging the complex code being developed there. 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.
