Windows blade runner shares big Swedish stage with Linux

IBM has built what could well be the largest ever dual booting Windows and Linux HPC blade system, comprising some 5376 Intel Xeon quad-core processors each of which is running at 2.5GHz and which will be able to reach a sustained 46 teraflops worth of processing power. Running Windows HPC Server 2008 (Beta) the high performance computing system has been built at the Umea University in Stockholm, Sweden and forms part of a resource used by a number of academic research groups.
In itself the system is sufficient enough of a powerhouse to lay claim to being one of the top 50 most powerful computers on the planet, which should be enough for any geek to get excited about. However, I suspect that the bit of the announcement that will get the most coverage will be that this one has been built around Linux and Windows rather than Linux alone. Heck, look at the statistics and it appears that around 85 percent of such HPC systems are running exclusively on Linux and Windows cannot even claim to scoop up the remaining 15 percent but instead sits somewhere around the 2 percent mark at the most (if you use the latest available Top 500 list as your metric anyway.)
This could all change when the latest Top 500 list is released later this week, Microsoft is certainly hoping to start making a bigger impression and has been investing heavily in the HPC market of late. I don’t think that the Linux fanboys have too much to worry about though, as it would take something of a seachange in the HPC world to shift even to the point where half the machines were dual-booting let alone Windows exclusive. I’m not sure I am even convinced by the argument that as people using Linux-powered high performance computers more often than not will be using Windows-powered desktops or laptops at home or outside of the research lab so there is a ready made market for the dual boot option.
