Australian Military Plays Games With Xserve

The Big Mac supercomputer cluster at Virginia Tech is an amazing piece of work on several fronts, not the least of which is its bang for buck. Big Mac cost a mere five million dollars, yet it is ranked as the world's third fastest computer. If you consider that each of the other top five fastest supercomputers cost many times what Big Mac did, you can see why the folks at Virginia Tech has caused such a stir; they've proven that supercomputing does not have to be high priced.

Possibly taking a cue from Virginia Tech, the Australian Military has recently put together a cluster of 16 Xserves for use in that country's war gaming effort. From a Computerworld Australia article, Apple plays 32-processor war games:

After a long stint on the sidelines of enterprise and government IT, Apple Computer has gained local traction in the defence sector. The Defence Science and Technology Organisation (DSTO) is showcasing an Xserve cluster to model battle scenarios based on the games of chess and checkers.

Dubbed Checkmate, the DSTO supercomputer-on-a-budget consists of a 16-node cluster of 1.33MHz G4 dual-processor Xserve systems (32 processors in total), each with 1G of RAM. The cluster operates on OS X 10.2.4 Jaguar, with each Xserve running multiple instances of Java-based simulation and analysis code to crunch through terabytes of what research mathematician Greg Calbert calls "second order" battle scenarios, or factors.

Second order factors are those beyond more rudimentary equations such as sheer military might and speed to consider the way scenario players interoperate and relate to each other.

"In the first order we [already] know having better tempo, better force strength [etc] to be true. We know we want better battleships, more networking - but it's a matter of how we distinguish between those factors," Calbert said.

To obtain such refinements, the G4 cluster grinds its way through specially crafted variants of what are already highly computation-intensive games.

"One of the variants of chess and checkers we play is 'network checkers'. The pieces are connected in a network [and] we look at where they are, and exchange that [position] with other pieces [including] the values of their prospective moves. They communicate and find what is the best move.

The Mac Observer Spin:

If last year was the 'Year of the Laptop' at Apple, this year must be the 'Year Apple Returns to IT'. When Steve Jobs announced the new G5 Xserve, Xserve RAID, and talked about Virginia Tech's accomplishments with Big Mac at Macworld San Francisco, the crowd applauded enthusiastically, but IT wasn't the highlight of that keynote. If you take a closer look at what's going on at Apple you might see signs that would agree with the assessment made by David Morgenstern of eWeek just before Macworld.

Not only did Apple offer up new hardware, a key piece of software was also announced that could be the key to an increased presence of Apple in IT server rooms around the world; Xgrid

Xgrid makes any group of Macs, not just Xserves, act as a networked supercomputer, basically similar to Big Mac. With Xgrid, any idle Mac can be instantly added to a computing cluster that is working on some problem. So, in academia and in the scientific world, where number crunching on a budget is the rule, buying Macs and Xserves has just become more attractive. Even commercial IT shops can see the benefit in virtual clustering.

OS X Panther is also far more eager to work and play well with other OSes. Apple in a Windows world is no longer the odd machine out since it integrates well with UNIX/Linux and Windows, and still has the distinction of being the only UNIX based platform that can run MS Office natively.

Also, Xserve RAID, as Jobs announced at Macworld, has been certified to work with a variety of systems, not just Xserve and OS X. IT shops looking for cheap storage now have yet another option, which, in turn, get Apple more accepted in the IT world.

We suspect we'll see a lot more articles like this one in the coming 11 months, and that, as we like to say, is a Good Thing™.
