From May 9 to 12, 2010, the Dagstuhl Seminar 10191 Program Composition and Optimization: Autotuning, Scheduling, Metaprogramming and Beyond was held in Schloss Dagstuhl Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abs...

This paper demonstrates the feasibility of constructing fault-containing, self-stabilizing protocols that allow the user to ne-tune the performance of the protocols, via the choice of values for certain program parameters. Based on the fault-history of the protocol, the user can choose appropriate values for program parameters and select desirable performance guarantees from various classes of ...

Parallel architectures with node-level accelerators promise significant performance improvements over conventional homogeneous systems. To cope with the increased complexity of programming such systems various pattern-based programming libraries have become available. In this paper we present our work on providing autotuning capabilities for two runtime libraries that provide parallel programmi...

UNLABELLED Amusia is a disorder that affects the processing of music. Part of this processing happens in the primary auditory cortex. The study of this condition allows us to evaluate the central auditory pathways. OBJECTIVE To explore the diagnostic evaluation tests of amusia. METHOD The authors propose an evaluation protocol for patients with suspected amusia (after brain injury or compla...
