Shared Supercomputing and Everyday Research

PORTLAND, Ore. — For decades, the world’s supercomputers have been the tightly guarded property of universities and governments. But what would happen if regular folks could get their hands on one?

The price of supercomputers is dropping quickly, in part because they are often built with the same off-the-shelf parts found in PCs, as a supercomputing conference here last week made clear. Just about any organization with a few million dollars can now buy or assemble a top-flight machine.

Meanwhile, research groups and companies like I.B.M., Hewlett-Packard, Microsoft and Intel are finding ways to make vast stores of information available online through so-called cloud computing.

These advances are pulling down the high walls around computing-intensive research. A result could be a democratization that gives ordinary people with a novel idea a chance to explore their curiosity with heavy computing firepower — and maybe find something unexpected.
