General Unix Even though the old-world UNIX operating systems, like IRIX and HP-UX, have been steadily losing ground to Linux for a long time now, they do still get updated and improved. HP-UX 11i v3 is supposed to get update 4 tomorrow, with a host of new features that won't excite you if you're used to Linux, but they're still pretty useful for HP-UX users.

Yes, Linux is frequently used on supercomputers, because it's free and there is source code available so it can be modified to work with custom machines. What's your point?

His point was in reply to the person questioning whether Linux scaled to the kind of hardware HP-UX runs on. The answer being a very definite *yes*.

The answer is most likely no. Not to repeat myself again I'll insert link: http://www.osnews.com/thread?354393
Btw it that graph there were also Windows, does that mean Windows scale great too?

Right, and do you think that matters if you are purchasing a tens of million Euros (dollars) supercomputer?

There are two reasons Linux is used on supercomputers:

- It has become the standard UNIX(-ish) platform that runs on scientist workstations up to supercomputers. Meaning that you can do stuff at every level with the same familiar environment (both API and userland).
- It's scalable enough for supercomputer applications.

Eventually Linux will kill off all other UNIXen (except for Darwin/OS X). Even the remaining UNIX server vendors (IBM and HP) invest quite heavily in Linux, if they can keep their hardware customers and ice their UNIX offerings, there is a much better profit margin for them. Oh, and it is what customers request ;) .

Sorry there, Linux will never kill off the BSD family, primarilly FreeBSD. I also doubt Solaris is going to die any time soon. If anything, given another year of development I would say Solaris would be better suited for desktop OS up to super compuers for a common environment. I anxioulsy await the day.

I think it does. AFAIK most OSes for this kind of machines used to be licensed per cpu, that makes a lot of money on a machine with hundreds of cpus. Also if you have a custom machine (which supercomputers are) you also need a customised OS and it's easier to grab FOSS then go through signing of NDAs and stuff.

Yes, they mostly build drivers for their hardware. Otherwise they develop their own OSes.

Maybe, I've never seen any statistics, but I used to work at one of those companies and only a small minority of customer ran Linux.
