Many-Task Computing on Many-Core Architectures

Many-Task Computing (MTC) is a common scenario for multiple parallel systems, such as cluster, grids, cloud and supercomputers, but it is not so popular in shared memory parallel processors. In this sense and given the spectacular growth in performance and in number of cores integrated in many-core architectures, the study of MTC on such architectures is becoming more and more relevant. In this...

Ultra-Low-Energy DSP Processor Design for Many-Core Parallel Applications

Background and Objectives: Digital signal processors are widely used in energy constrained applications in which battery lifetime is a critical concern. Accordingly, designing ultra-low-energy processors is a major concern. In this work and in the first step, we propose a sub-threshold DSP processor. Methods: As our baseline architecture, we use a modified version of an existing ultra-low-power...

Skeletons for multi/many-core systems

We discuss how algorithmic skeletons (and structured parallel programming models in general) can be used to efficiently and seamlessly program multicore as well as many-core systems. We introduce a new version of the muskel skeleton library that can be used to target multi/many-core systems and we present experimental results that demonstrate the feasibility of the approach. The experimental re...
