an example of a cutting-edge multicore system with VFI architecture. Energy -aware task scheduling in VFI-based multicore systems has been addressed in recent studies. The works in [15]-[18] used Mixed Integer Linear Programming (MILP) to formulate task scheduling and VFI partitioning, but

long-term component availability of single core processors. This has led some to adopt multicore processors but disable all but one core, as they can't economically verify the system when all cores are enabled. This isn't a good long-term solution and doesn't take advantage of the performance improvements offered by using multicore

Thus, understanding the most efficient design and utilization of these systems, in the context of demanding numerical simulations, is of utmost priority to the HPC community. In this paper, we present an application-centric ap-proach for producing highly optimized multicore imple-

The starting point of our cluster algorithm is the pipelined strategy on a single multicore processor presented in our earlier paper [1]. This section is devoted to an overview of this strategy. A. Overall Approach Briefly, a number of parsers run in parallel on the multicore CPU, where each parser reads a fixed size

multicore processors is moving at a rapid pace but developing software and programming models is slow. For exploiting multicore resources, a new task decomposition algorithms is presented. This algorithm considers the intra-task parallelism. Oriol et al. [15] present FASA as a scalable component framework for distributed control systems. FASA .

as systems get more sophisticated. In particular, modern multicore machines make the behaviour of algorithms hard to forecast and model. In this paper, we tackle the issue of tuning a dense QR factorization on multicore architectures. We show that it is hard to rely on a model, which motivates us to design a fully empirical approach.

technology or by reducing functionality, but a more practical solution is multicore processors where two or more processor cores are placed closely together in the same integrated circuit die. Going from one core to two intuitively doubles the computation power while preserving clock speed. Multicore processors are not without disadvantages .

introduction of multicore processors provide s a new challenge for software developers, who must now master the programming techni ques necessary to fully exploit multicore processing potential. Task parallelism is the concurrent execution of independent tasks in software. On a single-core processor, separate tasks must share the same processor.
