Facing up to parallelism

Multicore means today's HPC is tomorrow's general purpose It is, perhaps, one of those forgotten facts that computing is still a relatively young technology, made all the more poignant by the realisation that many of the people driving the High Performance Computing (HPC) business, like Burton Smith, Microsoft's technical fellow in charge of advanced strategies and policies for the company, have not only been round the track several times, but are very much still at the bleeding edge of the technology.â¦

Continuing the thread on commoditization of scalable server software, the third installment. Yesterday, Matt Tucker from the OpenFire community, said: "I'm not sure that S3 magically kills off the scaling priests. It certainly makes it easy to turn on more storage resources, but writing an application to scale efficiently across multiple virtual machines is no easy task." To which I responded... It won't make scaling obsolete, but what it does do is commodify it. Right now I can't buy a Jabber server that scales without also hiring someone who will scale it for me. But in a few years I should be able to buy a Jabber server that, when it needs more CPUs, just asks for them all transparently to the user, the same way my word processor asks the OS for more memory today. I remember word processors that didn't do memory management, you got a 64K buffer and that's it. One document. When you filled it up, you started another. Technology will go forward and scaling won't be a black art, it'll be something built into the software you license.

Never to be left outdone for long, AMD answered Intel's challenge yesterday at a press event in San Francisco, unveiling a system design that, while not a single CPU, makes the case for "teraflop on a budget."  It's a four-processor system that uses a pair of Opterons and a pair of co-opted ATI R600 graphics chips.

Many useful programs take arguments and configuration options. It's easy to add one or two, but as your program grows, the difficulty of allowing configuration concisely and intelligently also grows. Jon Allen demonstrates how to unify argument and configuration processing in a way that lets you write good code and your users get on with their work.
