HPC solutions: TotalView on AlphaServer systems

	Colored GUI with specific enhancements for Tru64 UNIX
	HP and Etnus Inc. have collaborated to bring you an enhanced version of TotalView on HP's high performance AlphaServer UNIX systems Mutex & condition variable information MPI & PVM support on Tru64 UNIX Compiled patch points and fast conditional breakpoints

The TotalView Multiprocess Debugger is a full-featured, source-level, graphical debugger for C, C++, Fortran 77 and 90, assembler, and mixed source/assembler codes. It has an intuitive, easy-to-learn interface with a user-friendly color GUI that enables software developers to debug complex multiprocess, multi-threaded, and distributed programs from a single session.

TotalView running on Tru64 UNIX displays mutexes (mutual exclusion locks) and condition variables in multi-threaded programs. These data objects allow multiple threads to synchronize access to shared resources. TotalView supports the debugging of distributed applications that use Compaq MPI. Also unique to Tru64 UNIX is TotalView's support of compiled patch points, which allow users to plant very fast conditional breakpoints and EVAL points in their program.

TotalView was designed from the beginning with multiprocessing in mind. It includes debug support for multiple threads and multiple processes.

TotalView can manage multiple processes and multiple threads within a process simultaneously. It keeps users in command by displaying each process or thread in its own window, which shows its source code, stack trace, and stack frame. Users can display all windows simultaneously, and perform and coordinate all debugging tasks across processes and threads, enabling the programmer to observe and control complex multiprocess interactions and detect subtle inter-process bugs.

TotalView provides the most extensive set of debugging capabilities available today. TotalView lets you temporarily insert compiled machine code fragments right into the program while you're debugging - a great time saver when you're testing bug fixes. You can write conditional break point descriptions in your favorite programming language such as C or Fortran, to avoid the limitations of a scripting language. You can debug code that was not compiled with the -g switch, or for which you don't have access to the source file, because TotalView provides machine-level debugging features. You can debug remote programs over the network because of TotalView's distributed architecture, enabling you to fix programs running on machines for which you don't have physical access. And you can attach to running processes, which means that you can debug processes that were not started under TotalView.

TotalView can handle the latest innovations in parallel and distributed programming - a boon to programmers who live on the "bleeding edge" of technology. TotalView supports industry standards for parallel and distributed computing, providing the tools you need to understand the behavior of complex parallel programs. With TotalView, you can debug programs that are on separate machines - of the same architecture type - over the network. TotalView can manage multiple remote programs and multiprocesses programs simultaneously.

TotalView is undaunted by large, complex programs. TotalView easily handles huge symbol tables, the downfall of ordinary debuggers. TotalView's just-in-time symbol table evaluation means quick start-up times on debugging big programs. And TotalView's data visualization capability lets you easily pick out anomalous points in large data sets and actually see when they first appear at run-time.
