Etnus has begun beta testing TotalView 7.3, the industry standard for debugging multiprocess and multithreaded HPC programs on Mac OS X, Linux, and UNIX. This latest version of TotalView adds full support for the new Intel Core Duo-based product line from Apple — including MacBook, iMac, and Mac mini — as well as Solaris-Opteron. The TotalView memory debugger is now available on all of these platforms as well as Power Mac. It lets programmers interactively locate problems that otherwise would be found with difficulty using post-mortem dumps.
