Etnus LLC, the world's leading provider of debugging solutions for high-performance computing environments, announced today that it has added support for TotalView's powerful memory debugging capabilities to the Cray XT4 supercomputer product line. TotalView is the primary memory debugging solution for this architecture.

TotalView is the world's most advanced debugger on Linux, UNIX, and Mac OS X. It enhances developer productivity by simplifying the process of debugging data-intensive, multi-process, multi-threaded or network-distributed applications. TotalView's interactive memory debugger helps find and eliminate memory problems as code is debugged. Since memory debugging capabilities are built-in, it is less intrusive than other memory analysis tools and eliminates the need to switch tools and re-compile.

"TotalView has been a valuable tool used by many Cray customers to debug their applications rapidly and effectively," said Steve Scott, Cray's chief technology officer. "We believe that integrating TotalView's memory debugging capabilities into our Cray XT4 system will further improve our customers' productivity."

The Cray XT4 system offers a new level of scalable computing for single, powerful computing systems handling the most complex problems. The system is purpose-built to meet the specialized needs of capability class high-performance computing applications, to operate efficiently and reliably at large scale.
