3 Mission and Vision Mission Our mission is to deliver scientifically excellent and industry relevant research in the fields of high performance computing and embedded systems. We are providing stateof-the-art technology and expertise in high performance computing and embedded systems and make it available for Czech and international research teams from academia and industry. Vision To became top European Centre of Excellence in IT with the emphasis on high performance computing and embedded systems. With our research, know-how and infrastructure we aspire to improve the quality of life, to increase the competitiveness of industrial sector and to promote the cross-fertilization of highperformance computing, embedded systems and other scientific and technical disciplines.
