Multi-OS, and dual-boot machines I'd assume.

Who does that on a super computer?

That's a good question,

I would presume you could keep your Super Computer crunching or calculating while doing something else in a virtual machine, which would qualify as a mixed OS.

Your guess is as good as mine.

could mixed mean that some control terminal(or whatever you call what is used to send these number crunching monsters their next batch of jobs. as I am going to guess Titan has no keyboard and monitor port itself.) So would it be mixed if say a terminal running windows was sending the super computer jobs via SSH in Putty?

Or a workstation running Linux was sending commands to the super computer which is running Unix or BSD. would that count as one unit still and as such make it "mixed"

Some processor nodes run one operating system, other nodes run a different operating system.

This might be done when the archiecture is such that different nodes have different specialization, e.g., compute node versus I/O node.

Lots of them

I was reading about one of the top10 awhile back
they had a mix of unix linux and BSD for different roles in the system

all one huge cluster with roles parted out into different clusters

the storage servers ran one OS that they picked was most ideal for it

the CPU crunching ran another

and I forgot what ran the third
