A supercomputer under every desk is what Mr. Gates is pushing now, even though at the moment that would be to Microsoft's disadvantage. Although under every desk may be a bit of a misnomer, the idea of a small set of powerful clustered machines able to fit in ordinary environments, such as typical office, is very feasible.

""What we see as a key trend here is that we will have supercomputers of all sizes, including ones that will cost less than $10,000 and be able to sit at your desk or in a department," Gates said."
Gates himself admitted that Linux and Unix are choice when it comes to operating extremely powerful machines, but that Microsoft - of course - is working to catch up. Clustered Windows servers are apparently not far off. With the increase attention towards blade PCs and VT, it's a wonder where clustering for small environments will fit in.
