Microsoft is on a mission to persuade small companies they need -- and can manage -- affordable HPC systems that run on the familiar Windows system.

HPC is any type of computing system that uses more than one computer working in parallel or clusters to solve complicated problems in fields such as engineering, meteorology or genetics.

It includes the so-called supercomputers used by the likes of CERN, the world's largest particle-physics lab.

So far, Microsoft has about 2 to 3 percent of the market, according to market research firm IDC, with the vast majority of HPC systems running on open-source Linux or its cousin, Unix.

But Kyril Faenov, who is heading Microsoft's HPC drive, is bullish about the company's prospects.

"Windows server has over 60 percent market share in markets where Microsoft is active," he told Reuters. "We're aspiring to the same share as we have in other markets. That's a comfortable target for us."
