Computerworld reports that a computing research center in Iran claims to have used Advanced Micro Devices Inc.'s Opteron processor to build the Middle Eastern country's most powerful supercomputer, despite federal antiterrorism trade sanctions that bar the sale of U.S.-made computer technology to the country. The Iranian High Performance Computing Research Center (IHPCRC), which is located at Tehran's Amirkabir University of Technology, says in an undated announcement on its Web site that it has assembled a Linux-based system with 216 Opteron processing cores. That's a relatively small supercomputer, with a claimed peak performance level of 860 billion floating-point operations per second, or gigaflops. But the research center said that the system, which will be used for weather forecasting and meteorological research, is the fastest built in Iran to date.

XMonad, a tiling window manager written in under 1000 lines of Haskell, recently released version 0.4. New features include a rule system, user-specified workspace tags, and serialisable layouts, as well as many new extensions (the contrib library is several times the size of xmonad itself). See a guided tour or just get started; make sure to /join #xmonad on irc.freenode.net.
