The progress and change in research methodology are the driving force of putting finance science forward.As a new finance research methodology, by using a lot of hardware and software necessary for high-performance com-puting, computational finance makes it possible to model and predict the evolution of some finance problems such asfinance market simulation and security pricing. This paper discusses the composition and connotation of computationalfinance, analyzes the basic characters of high-performance computing, and introduces three exploration and applica-tion in computational finance researches including: security pricing and risk calculations; integrated financial productmanagement; financial innovation and the computer-aided design of financial products.
