Etnus today announced the release of a new version of TotalView 7.3 featuring support for the Intel Core Duo processor-based Macs. TotalView Version 7.3 supports Apple's build of the GCC compiler, as well as the Intel compiler suite. In addition, it provides integrated memory debugging for Power Mac OS X and Intel Mac OS X, a data viewer for dumping memory contents, and an MPI message queue graph that performs cycle detection. TotalView supports threads, MPI, OpenMP, C/C++, and Fortran, plus mixed-language codes and offers advanced features such as on-demand memory leak detection, other heap allocation debugging features, and a Standard Template Library Viewer (STLView). Developers can leverage a wide variety of breakpoints, the Message Queue Graph/Visualizer, powerful data analysis, and control at the thread level. It supports Mac OS X 10.4 or later.
