Do you realize that linux is on 90% of the supercomputers? Thinking about it this is a great achievement for an operation system that was created in the dorm room of Linus Torvalds in 1991. When he was asked to comment on the reason he wrote:
that Linux has caught on in part because while typical Unix versions run on only one or two hardware architectures, Linux runs on more than 20 different hardware architectures including machines based on Intel (nasdaq: INTC - news - people ) microprocessors as well as RISC-based computers from IBM and HP (nyse: HPQ - news - people ). “Of course, of those 20, only a handful are relevant for high-performance computing, but it’s still a big advantage,” says Torvalds
Well as Jay lyman says linux shows no signs of slowing down and why would it, it is a great OS.
