  • 02-18-2009 - Great Tips on SSDs

    There is a new article at PC Perspective that talks about the really hot Intel SSDs. But it goes beyond a normal review and gets into some of the guts of SSDs and talks about an important topic: file system performance as it ages. So, I want to write about the review and point out the file system aging...
  • 04-08-2009 - Nehalem and Memory Configurations

    The Intel® Xeon® processor 5500 series architecture (code named, "Nehalem")–based systems bring a whole new level of memory bandwidth to the high-performance computing (HPC) party. But the new architecture brings with it some options that allow you to trade memory price, memory...
  • Duke University HPC: Higher Performance with Less Power

    At Duke University, over the past two years, we've been collecting power consumption data across 500-600 machines of the Duke Shared Cluster Resource (DSCR). The DSCR is a large Linux cluster - over 4100 CPU-cores - that provides "production-grade" computational capabilities for over 70...
  • Cluster Performance- It's not just about Clock Rate Anymore.

    By Dan Stanzione and Tommy Minyard, Texas Advanced Computing Center For a long time now, we've known that sustained performance on clusters is a complicated thing to measure, especially when talking about parallel jobs. In columns like this one, and others too numerous to count, it has been stressed...
