Abstract
With the failure of Dennard's scaling, which stated that shrinking transistors will be more power-efficient, computer hardware has today become very divergent. Initially the change only concerned the number of processor on a chip (multicores), but has today further escalated into complex heterogeneous system with non-intuitive properties -- properties that can improve performance and power consumption but also strain the programmer expected to develop on them. Answering these challenges is the OpenMP task-parallel model -- a programming model that simplifies writing parallel software. Our focus in the thesis has been to explore performance and quality-of-service...
