Nice to know I’ve had an impact on language …

From this article linked from /., I found this tidbit Core Business In order to make current operating systems compatible with AMD’s core architecture, the FPU somehow has to operate with a kind of hyper-threading, so that the operating system, and its users, can accept the whole design as a full-fledged duo-core. The 8-core processor […]

IBM shelves Cell

It looks like IBM is going to shelf the Power Cell processor. Cell during its lifetime never really garnered the ubiquity it needed to do what NVidia is doing with GPU. I had guessed on this site previously that Cell needed to get wider distribution to maintain a base. The business model for acceleration is […]

I keep forgetting how brittle anaconda is …

… until I need to use it. Anaconda is the Redhat/Fedora installer. It purports to be a reasonable installation tool. But it has a number of interesting issues. Some of these issues make installs … well … exciting. I’ve taken to the philosophy of absolute minimum time spent in anaconda. Call this defensive installation. Anaconda […]

Designing the next generation of our storage systems

Back from SC09, and for a project Vipin asked me to work on quickly, I am cranking out our roadmaps in greater detail. One of the things I’ve been thinking of for a long time is, what comes after JackRabbit and DeltaV? In the case of JackRabbit, even when it is hobbled by a poorly […]

One of the best (funniest) quotes from #SC09

From HPCwire … “Moving a physical disk-head to accomplish random I/O is so last-century,” said Allan Snavely, associate director of SDSC, co-principal investigator for SDSC’s Gordon system and project leader for Dash. “Indeed, Charles Babbage designed a computer based on moving mechanical parts almost two centuries ago. With respect to I/O, it’s time to stop […]

#sc09 [T+2] user benchmarks of the MSI storage cluster

Minnesota Supercomputing Institute purchased the first siCluster (PR on disk, finishing up and getting out tomorrow), which is a scalable storage cluster product, aimed at providing very scalable performance and capacity. I was worried after the talk I gave at their booth. Their researcher indicated our performance wasn’t good. We had turned off some caching […]

#sc09 [T+2] its like drinking from a fire hose …

Ok … so so many things going on. All at once. I’ve done what … like 3 on camera interviews over the last 48 hours, and have another one coming up. I’ve given a talk, and attended a talk. More on that in the next post. Ok. Vipin needs me to work on something tonight, […]

#sc09 [T-0] NFS over 10GbE at 1 GB/s

Just thought we’d run some nice little performance tests using io-bm (yeah, I know, I have to release it already). Remember, this is booth 635 if you want us to do this live … Here is a write, from the Pegasus, to the JR4. Over a single 10GbE link. Viewed 16576 times by 3918 viewers

#sc09 [T-0]: The demo …

So we worked hard with our partners to get a demo going. One that highlighted their software, and our hardware. And we got this going with their kind and patient help. One problem. It goes so fast … its done in about a second … 🙂 Viewed 11568 times by 2661 viewers
