Summary

Current multicore computers differ in many hardware char-acteristics. Software developers thus hand-tune their par-allel programs for a specific platform to achieve the bestperformance this is tedious and leads to non-portable code.Although the software architecture also requires adaptationto achieve best performance, it is rarely modified becauseof the additional implementation effort. The Tunable Ar-chitectures approach proposed in this paper automates thearchitecture adaptation of parallel programs and uses anauto-tuner to find the best-performing software architecturefor a particular machine. We introduce a new architecturedescription language based on parallel patterns and a frame-work to express architecture variants in a generic way. Sev-eral case studies demonstrate significant performance im-provements due to architecture tuning and show the appli-cability of our approach to industrial applications. Softwaredevelopers are exposed to less parallel programming com-plexity, thus making the approach attractive for experts aswell as inexperienced parallel programmers.
