Linux, x86 clusters take over top 500 supercomputer ranking (CBR)

[Posted November 10, 2004 by corbet]

Computer Business Review looks at the trends at SuperComputing 2004. "It wasn't all that long ago that the entire Top 500 list was measured in tens of teraflops, and when Lawrence Livermore National Laboratory takes final delivery of Blue Gene/L early next year, this behemoth will have 131,072 customized PowerPC 400 cores running at 700MHz and it will deliver over 360 teraflops of peak computing power. Blue Gene/L, as you might have guessed from the name, runs a cut down version of Linux on its compute nodes and Novell's SuSE Linux Enterprise Server 9 on its I/O and management nodes."

I've hunted through the Top500's database before, and I've never been able to find a way to count how many of the Top500 machines run Linux. They do appear to track operating systems for each machine, and you can find the operating system for each of the currently sold product lines (they're all Unix flavors, with Linux the most common), but their database doesn't appear to record OS, or at least you can't filter by it.

Has anyone seen or been able to get a number on how much of this list is run on Linux?
