Authors: David Chi-Leung Wong, Albert Cohen, María J. Garzarán, Christian Lengauer, and Samuel P. Midkiff

Abstract
From 02.09. to 07.09.2007, the Dagstuhl Seminar 07361 ``Programming Models for Ubiquitous Parallelism'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. 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 abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

A Case for Deconstructing Hardware Transactional Memory Systems

Authors: Mark D. Hill, Derek Hower, Kevin E. Moore, Michael M. Swift, Haris Volos, and David A. Wood

Abstract
Major hardware and software vendors are curious about transactional memory (TM), but are understandably cautious about committing to hardware changes. Our thesis is that deconstructing transactional memory into separate, interchangeable components facilitates TM adoption in two ways. First, it aids hardware TM refinement, allowing vendors to adopt TM earlier, knowing that they can more easily refine aspects later. Second, it enables the components to be applied to other uses, including reliability, security, performance, and correctness, providing value even if TM is not widely used. We develop some evidence for our thesis via experience with LogTM variants and preliminary case studies of scalable watchpoints and race recording for deterministic replay.

Parallelism through Digital Circuit Design

Authors: John O'Donnell

Abstract
Two ways to exploit chips with a very large number of transistors are multicore processors and programmable logic chips. Some data parallel algorithms can be executed efficiently on ordinary parallel computers, including multicores. A class of data parallel algorithms is identified which have characteristics that make implementation on multiprocessors inefficient, but they are well suited for direct design as digital circuits. This leads to a programming model called circuit parallelism. The characteristics of circuit parallel algorithms are discussed, and a prototype system for supporting them is described.

Some Experiments on Tiling Loop Programs for Shared-Memory Multicore Architectures

Authors: Armin Größlinger

Abstract
The model-based transformation of loop programs is a way of detecting fine-grained parallelism in sequential programs. One of the challenges is to agglomerate the parallelism to a coarser grain, in order to map the operations of the program to the available cores in a multicore architecture. We consider shared-memory multicores as target architecture for space-time mapped loop programs and make some observations concerning code generation, load balancing and cache effects.
