Book Description
Scalability of applications is a key requirement to gaining performance in hybrid and cluster computing. Implementing code to utilize multiple accelerators and CPUs is difficult, particularly when dealing with dependencies, memory management, data locality, and processor occupancy. The Hybrid Task Graph Scheduler (HTGS) is designed to increase programmer productivity to develop applications for single nodes with multiple CPUs and accelerators. Current task graph schedulers provide APIs, directives, and compilers to schedule work on nodes; however, many fail to expose the locality of data and often use a single address space to represent memory resulting in inefficient data transfer patterns for accelerators. HTGS merges dataflow and traditional task graph schedulers into a novel model to assist developers in exposing the parallelism and data locality of their algorithm. With the HTGS model, an algorithm is represented at a high level of abstraction and modularizes the computationally intensive components as a series of concurrent tasks. Using this approach, the model explicitly defines memory for each address space and provides interfaces to express the locality of data between tasks. The result achieves the full performance of the node comparable to the best of breed implementations of algorithms such as matrix multiplication and LU decomposition. The performance gains are demonstrated with a modest effort using the HTGS C++ API, which improves programmer productivity with obtaining that performance.

Book Description
This volume contains the proceedings of the 7th Workshop on Hybrid Systems: Computation and Control (HSCC 2004) held in Philadelphia, USA, from March 25 to 27, 2004. The annual workshop on hybrid systems attracts researchers from academia and industry interested in modeling, analysis, and implemen- tion of dynamic and reactive systems involving both discrete and continuous behaviors. The previous workshops in the HSCC series were held in Berkeley, USA(1998),Nijmegen,TheNetherlands(1999),Pittsburgh,USA(2000),Rome, Italy (2001), Palo Alto, USA (2002), and Prague, Czech Republic (2003). This year’s HSCC was organized in cooperation with ACM SIGBED (Special Interest Group on Embedded Systems) and was technically co-sponsored by the IEEE Control Systems Society. The program consisted of 4 invited talks and 43 regular papers selected from 117 regular submissions. The program covered topics such as tools for analysis and veri?cation, control and optimization, modeling, and engineering applica- ons, as in past years, and emerging directions in programming language support and implementation. The program also contained one special session focusing on the interplay between biomolecular networks, systems biology, formal methods, andthecontrolofhybridsystems.

Book Description
El-Rewini and Lewis were among the first researchers to recognize the problem of resource allocation (scheduling) inherent in parallel and distributed programs. Here they offer a clear explanation of the problems, methods to solve the problems under a variety of conditions, and an evaluation of the "goodness" of the solutions.

Book Description
Multiprocessor platforms play important roles in modern computing systems, and appear in various applications, ranging from energy-limited hand-held devices to large data centers. As the performance requirements increase, energy-consumption in these systems also increases significantly. Dynamic Voltage and Frequency Scaling (DVFS), which allows processors to dynamically adjust the supply voltage and the clock frequency to operate on different power/energy levels, is considered an effective way to achieve the goal of energy-saving. This book surveys existing works that have been on energy-aware task scheduling on DVFS multiprocessor platforms. Energy-aware scheduling problems are intrinsically optimization problems, the formulations of which greatly depend on the platform and task models under consideration. Thus, Energy-aware Scheduling on Multiprocessor Platforms covers current research on this topic and classifies existing works according to two key standards, namely, homogeneity/heterogeneity of multiprocessor platforms and the task types considered. Under this classification, other sub-issues are also included, such as, slack reclamation, fixed/dynamic priority scheduling, partition-based/global scheduling, and application-specific power consumption, etc.
