The HPC high-performance computing market is currently still dominated by Linux and Unix. If we look at the processors being run, the share of these two systems is over 90%.
However, supercomputing is being increasingly emphasized. The latest news from Microsoft indicates that at the SC07 conference, Microsoft believed that high-performance computing is becoming an indispensable part of business. The company has started to shift towards the technical design and experimentation of virtual environments, analyzing vast amounts of collected data. The scale of computing power in supercomputers is growing larger and larger, and applications need to be designed to operate in parallel across different processor cores.
