PVFS2 - a High-Performance Parallel File System
neillm78 writes "As part of the development team, we're announcing PVFS2 version 1.0 here in Pittsburgh at the SC2004 conference! PVFS2 is a GPL/LGPL based parallel file system for cluster-based applications. It logically groups any number of storage servers into a coherent file system for use by client nodes, specifically tailored to handle efficient access to large shared files. PVFS2 supports access via an MPI-IO interface for high-performance parallel applications, but you can still mount it like a regular GNU/Linux file system for traditional serial applications and managment. The PVFS2 project is conducted jointly between The Parallel Architecture Research Laboratory at Clemson University and The Mathematics and Computer Science Division at Argonne National Laboratory. Please feel free to give it a try!" -
Earth Simulator, G5 Cluster Drop In 'Top 500' List
daveschroeder writes "The November Top 500 supercomputer list has been published at SC2004. Topping the charts is IBM and the US Department of Energy's 'BlueGene/L DD2' beta system, at 70.72 TFlops, followed by NASA's 'Columbia' at 51.87.TFlops. For the first time in several publications of this list, Japan's Earth Simulator is no longer in the number one slot, falling to third. Virginia Tech's 'System X' Xserve G5 cluster, while 20% faster than the original cluster that debuted at number 3 last November, has fallen to number 7 due to the new entries, but remains the fastest supercomputer at an academic institution. Here's an excellent cost comparison (Google cache) of the top machines ('System X' is significantly cheaper than anything else in the top 20, not to mention cheaper than many things far below it in performance)." -
The Spinning Cube of Potential Doom
An anonymous reader writes "This month's Communications of the ACM (does not seem to have a link to online text) has an article about The Spinning Cube of Potential Doom, a security visualization tool that I first saw at SC2003. The cube displays data from Bro along 3 axes and creates interesting visual results (port scans, barber poles, lawnmower). This definitely makes patterns in all that 'boring log data' jump out. This is a very interesting development, the ability to monitor in real time and replay historical security related information. Definitely a step towards the new types of tools we will need to secure hosts and networks." -
World's Fastest Supercomputer To Be Built At ORNL
Homey R writes "As I'll be joining the staff there in a few months, I'm very excited to see that Oak Ridge National Lab has won a competition within the DOE's Office of Science to build the world's fastest supercomputer at Oak Ridge National Lab in Oak Ridge, Tennessee. It will be based on the promising Cray X1 vector architecture. Unlike many of the other DOE machines that have at some point occupied #1 on the Top 500 supercomputer list, this machine will be dedicated exclusively to non-classified scientific research (i.e., not bombs)." Cowards Anonymous adds that the system "will be funded over two years by federal grants totaling $50 million. The project involves private companies like Cray, IBM, and SGI, and when complete it will be capable of sustaining 50 trillion calculations per second."
