Business Editors/High-Tech Writers

NATICK, Mass.--(BUSINESS WIRE)--April 6, 2004

Etnus, the provider of TotalView(R), the most advanced debugger on Linux and UNIX, today announced the availability of TotalView 6.4, which increases support for Linux including new distributions and compilers, and Linux-specific debugging features.

The release also further extends TotalView's industry lead in data analysis capabilities.

The 6.4 release includes support for SuSE ES 8.2 on Linux x86, Red Hat EL 3.0 for Linux IA-64, and Red Hat Fedora Core 1 along with important new compilers such as Intel(R)'s Fortran 8.0 for Linux. TotalView also now supports Sun One Studio Compiler Collection, C/C++ and Fortran version 8.0.

This release also brings two significant GUI additions that enable unprecedented access to program data. The Expression List Window gathers and groups expressions that software engineers want to evaluate during debugging sessions. Developers simply place any expressions of interest in one customizable, feature-rich window to gain new insights on those variables' behavior every time the program is stopped. A companion window, the Data Window also lets users monitor interesting variables and structures. The new Data Window is a powerful feature, allowing users to perform "what-if" analyses, transform data to understand its affect on the program, set watchpoints on data, and much more. These features are available on Linux and the broad range of UNIX platforms that TotalView supports. (For a list of supported platforms see www.etnus.com).

TotalView 6.4 also bolsters Etnus' leading position in threads debugging, adding support for multi-threaded core files on Linux as well as the Native Posix Threads Library. Advanced Linux kernel features such as pre-linked shared libraries and the exec-shield feature are also part of this release.

"Providing the best debugging solution for our customers as they adopt new Linux compilers, distributions, and features is a top priority for Etnus," comments Mary Kay Bunde, Director of Market Development, Etnus. "We continue to add features and support for new compilers and Linux distributions to maintain and extend the leading position we have established among Linux tools."

TotalView is an advanced 32- and 64-bit graphical debugger providing software engineers with complete control over applications written in C, C++, or Fortran. It is the premium debugger for applications that use multithreading, MPI, or OpenMP, offering advanced features, such as heap allocation debugging, extensive data analysis, easy viewing of standard template library data, and a vast array of unique capabilities to find and eliminate problems in complex applications.
