High-performance computing has been developing fast enough, a very important reason is the lack of talent, and Windows platforms have the most extensive use of custom identification, Windows platform has a lot of developers, based on Windows platform to do high-performance computing, high-performance computing brings more people, will directly promote the development of high-performance computing.
