Functional High Performance Financial IT

Abstract. The world of finance faces the computational performance challenge of massively expanding data volumes, extreme response time requirements, and compute-intensive complex (risk) analyses. Simulta-neously, new international regulatory rules require considerably more transparency and external auditability of financial institutions, including their software systems. To top it off, increased product variety and cus-tomisation necessitates shorter software development cycles and higher development productivity. In this paper, we report about Hiperfit, a recently etablished strategic research center at the University of Copen-hagen that attacks this triple challenge of increased performance, trans-parency and productivity in the financial sector by a novel integration of financial mathematics, domain-specific language technology, parallel functional programming, and emerging massively parallel hardware. Hiperfit seeks to contribute to effective high-performance modelling by domain specialists, and to functional programming on highly parallel computer architectures in particular, by pursuing a research trajectory informed by the application domain of finance, but without limiting its research scope, generality, or applicablity, to finance. Research in Hiper-fit draws on and aims at producing new research in its different scien-tific fields, and it fosters synergies between them to deliver showcases of modern language technology and advanced functional methods with the potential for disruptive impact on an area of increasing societal impor-tance.
