Analysis of Performance and Power for Highly Parallel Systems Special issue of Concurrency and Computation: Practice and Experience (CCPE) ----------------------------------------------------------------------- This special issue will be focused on how performance and power properties of modern highly parallel systems can be analyzed using state-of-the-art modeling and analysis techniques, and real-world applications and tools. Complex, hierarchical architectures are now the standard for almost all highly parallel computer systems. Without a good grip on relevant performance limitations any optimization attempt is just a shot in the dark. Hence, it is vital to fully understand the performance properties and bottlenecks that come about with clustered multi- & many-core, multi-socket nodes. Another crucial aspect of modern systems is the complex interplay between power constraints and the need for compute performance. The challenges ahead are many-fold as systems scale in size. While parallelism is increasing, memory systems, interconnection networks, storage, and uncertainties in programming models all add to the complexities. More rapid realization of energy savings will require significant increases in measurement resolution and optimization techniques. The interplay between performance, power, and reliability also leads to complex trade-offs. Of particular interest are papers that identify and analyze novel ideas rather than providing incremental advances in the following areas: * Performance modeling techniques at core, socket, node, and system levels * State-of-the-art tools for analyzing performance and power * Novel techniques that enable power and/or energy optimizations * Experiences from current large-scale systems and applications * Analysis of future technologies that will provide improved energy efficiency ----------------------------------------------------------------------- Submission Guidelines Work that is submitted to this special issue must not have been previously published or currently being considered by other journal or conference venues. However, the papers that have been previously published with reputed conferences can be considered for publication in the special issue if they are substantially revised with at least 30% new content. Every submitted paper will receive at least three reviews. There is a 20 page max length limit (12 point single space, inclusive of figures and tables). Wiley has LaTeX templates that can be used by authors. Either LaTeX or Word submissions will be accepted. Submissions should be made through Manuscript Central (http://mc.manuscriptcentral.com/ cpe) and must refer to "PPHPS 2012 special issue" in step 4 of the submission process.
