What is the most common operating system for a supercomputer? Anyone know? Just curious as I imagine its not Windows based.
What OS do supercomputers use usually?

Unix/Linux.
SGI releases Linux supercomputer with Itanium processor
IBM lands DOE deal for fastest supercomputers
"Blue Gene/L will run at 360 teraflops, or 360 trillion calculations per second based on sets of two microprocessors working simultaneously. It will have 130,000 processors running Linux.
Blue Gene/L will be used by all three NNSA laboratories, the ASCI University Alliance collaborators as well as other DOE laboratories."

Don't know about the others but the OS's on Cray's were custom written for each box as they were usually built to just run one program.
UNIX or some home-brew of unix. Microsoft isn't taken seriously in the high world of computational computing.

Let's see... SGI has IRIX (and Linux), IBM has AIX (and Linux), Sun has Solaris, HP has HP-UX, Cray has some custom stuff I know nothing about.

8 is the best place to stop because after that the benefits diminish as the kernel doesn't scale that well yet. But the kernel itself can initialize and use 32 processors on 32-bit arch and 64 processors on a 64-bit arch, even though the overhead of managing all those processors would make it pointless currently. You also need to realize that most of those super computers are clusters, not one big box. They're either seperate entity boxes using distributed jobs (like a Beowulf cluster) or many boxes sharing resources in a NUMA fashion.
Then there's Tru64 from DEC/Compaq/HP which is being phased out in favor of HP-UX, can't forget about OpenVMS either. The majority of my employers income comes from jobs that run on a VMS cluster.

they take making money seriously. i can't stress enough that microsoft is the walmart of operating systems. once you hear that, it just makes so much sense doesnt it?
Can't say that I totally agree with your analogy. Saying that Microsoft == Wal-mart would be saying that they offer a wide selection of products that do many different things at good prices (not true the last time I checked, on Microsoft's partOriginally posted by: BingBongWongFooey

). You could truthfully say that Windows == "Great Value" (Wal-mart's generic brand), at least in terms of quality.So what your saying, is when a network admin is looking up his system mail, he doesnt hear "You Got Mail!" ? Who'd a thunk it?!
