NATICK, Mass. -- Etnus, the world's leading provider of debugging solutions for complex code, today announced the availability of TotalView 6.2, for Intel(R) Itanium(R) 2-based HP servers and workstations. TotalView is a full-featured, source level, graphical debugger providing software engineers with complete control over threaded and parallel applications written in C, C++ or Fortran. Its features simplify debugging and analysis of applications and offers unrivaled support for code that uses multithreading and MPI on both distributed memory and shared memory computers. With advanced features not found in other debuggers, TotalView is unrivaled in its ability to help find bugs fast. The Itanium processor's floating-point performance, 64-bit addressing, and large cache memory are well-suited to a wide range of technical computing requiring large, multi-process applications. "Etnus finds synergy with HP's target markets in that we have experienced considerable growth within engineering, entertainment, research and other markets," observed Etnus President and CEO Christopher Doehlert. "The applications that drive these markets are becoming more and more complex. Etnus TotalView is in a unique position to provide customers with the advanced debugging and data analysis capabilities they need." TotalView supports Intel compilers for Linux on both the Intel(R) Itanium(R) architecture and IA-32 architectures, such as the Intel(R) Pentium(R) 4 processor. "TotalView is a fundamental part of HP's High Performance Technical Computing software development infrastructure," said Winston Prather, vice president, HP High Performance Technical Computing Division. "With TotalView, customers will be able to efficiently debug their complex scale-up and scale-out HPTC applications." Complexity, parallelism, and the sheer size of an application can add to the challenge programmers face in making application logic work properly. TotalView is designed for such environments, especially when parallelism is employed and in situations where developers are taking applications from 32-bit systems to larger, faster 64-bit systems such as the Itanium 2 systems from HP. When porting to 64-bit architectures, software engineers commonly experience problems with constructs like C pointers as well as data originally written to align on 32-bit boundaries. TotalView's advanced language support, parallel support, and data analysis features ease the debugging involved in these ports.
