Ok i have searched google.com and have a book on supercomputing but i can't seem to find information on if you can make a supercomputer that just runs normal linux. I mean i have seen heaps of SC's that do specific OS that run calculations.
But can u make a supercomputer that runs Linux?

p.s. not a dual cpu computer
p.p.s. a multi node supercomputer, not a commercial bought one (cray, etc)
