Dell has leapfrogged HP to capture the #2 top HPC vendor crown!
IBM, followed by Dell, was the top named [HPC] vendor for number of nodes installed when outliers (i.e., systems with 2,000 or more nodes) were excluded. Click for full article
I’m sure that most users reading this are using HPC systems with less than 2000 nodes. It’s the core of the HPC market and Dell has captured a very large portion of it.
Our goal in this report was to discover system-level trends within the HPC user communities by examining supplier penetration, architecture trends, and node configurations. As with previous years, we surveyed a broad range of users about their current computer system installations, storage systems, networks, middleware, and the applications software supporting these installations.
Take a look at my recent article over at HPCatDell.com regarding the Supercomputing landscape in Formula One racing. Here’s a snippet from the post:
HPC technology enables F1 engineers to test hundreds of ideas virtually, and select those that perform well for physical testing, saving F1 teams both time and money. Its importance has been recognized with new regulations that limit F1 teams to 20 teraflops of compute power.
HPC solutions have transformed the competitive landscape of Formula One racing. Which industry is next?
What do you think?
One of my Dell HPC colleagues, Dr. Jeff Layton, has put together a great guide for getting started with Logical Volume Management on Linux. LVM on UNIX based platforms has been around for a long time, but is relatively new (and now stable) on Linux within the last few years.
Over the years, I’ve used GUI volume managers on Solaris (Veritas), AIX (LVM), and HP-UX (SAM), but they were proprietary and expensive. LVM on Linux is a great solution. You may balk at using a GUI, but when you have your companies’ critical data on the line, there is nothing like “seeing” your volumes before you manipulate them. For me, storage management was probably the most stressful part of UNIX/Linux system administration, because if you screwed up, you could lose data. It is worthwhile to use all the tools at your disposal (even a GUI!) to make sure you aren’t, for instance, removing the wrong disk from the wrong logical volume.
