Framingham, MASS. — Etnus, a leading supplier of parallel application debuggers for the UNIX and Linux markets, announced the rapid adoption of TotalView, the first parallel debugger and analyzer to address the needs of the Linux market.

A “Linux Developer Opinion Survey” recently conducted by research house Evans Marketing Services, indicated a lack of adequate development tools for Linux. “We began addressing the need for advanced Linux cluster development tools earlier this year when we introduced a Linux version of the Etnus TotalView debugger and analyzer,” explained Chris Doehlert, president and CEO of Etnus. “In recent months, we’ve seen a two-fold increase in the demand for TotalView on Linux platforms. This clearly indicates that as Linux clusters become more commonplace, there is a corresponding need for quality development tools.”

TotalView is the only multiprocess, multithread application debugger/analyzer that supports Fortran, C and C++ languages along with the major parallel programming paradigms including MPI, threads, and OpenMP.

GUI-based, it shortens development time via an easy-to-learn and easy-to-use “select-and-dive” approach. It enables developers to unravel and control multiple threads and processes running on single or multiple processor systems.

The analyzer automatically acquires processes and threads in multiprocess programs, provides developers greater flexibility in controlling the program and graphically displays data arrays. Users can easily dive on program objects and structures for more detail.

The Ohio Supercomputer Center (OSC) was a beta test site for TotalView on Linux. After seeing the capabilities of the analyzer and having received numerous requests for its use, they purchased TotalView for Linux and their statewide network. The use of TotalView is incorporated into the advanced programming classes taught at OSC. “It offers advanced support such as OpenMP and MPI, and is the only debugger available that works on all our systems and across OARnet [a networking initiative that provides Internet access to the majority of Ohio’s colleges, universities and state government agencies],”

explains Doug Johnson, system developer/engineer with OSC.

“As major corporations and research centers alike choose Linux to solve mission critical problems, the demand for advanced development tools like TotalView skyrockets,” comments Mary Kay Bunde, director of market development for Etnus. “TotalView is specially designed to seamlessly debug complex codes running on Linux clusters. Software engineers worldwide appreciate its advanced time-saving features, unparalleled flexibility over program control and ability to automatically acquire processes as they start.”

Tripwire, Inc., a leading provider of Integrity assessment security solutions for Global 3000 e-commerce and e-business corporations, recently put TotalView through its paces by porting its C++ application, Tripwire HQ Connector to Redhat Linux along with DEC Alpha, IBM AIX-RS6000, HPUX, SGI IRIX-MIPS, and Sun Sparc Solaris. Tripwire engineers found that TotalView excelled in its ability to easily debug multiple threads and forked processes while maintaining a consistent graphical debugging environment. As an added benefit, ramp-up time was almost non-existent. After downloading TotalView from the web, the Tripwire team was productive within 20 minutes.

Etnus was previously the ToolWorks group of Dolphin Interconnect Solutions, and was established as a wholly-owned business in August, 1998. During 1999, Etnus achieved more than 50% growth in gross revenue with even faster growth in license and maintenance sales.

Etnus supplies developers and major system vendors with application debuggers/analyzers that provides visibility into multiprocess and multithread programs, and control over the correction of their problems. TotalView scales beyond the capability of any other debugger and is being used on systems of all sizes in a wide range of industries, including aerospace, telecommunications, finance, manufacturing, and research.
