Ultrarelativistic QuantumMolecular Dynamics is a physics model to describe the transport, collision, scattering, and decay of nuclear particles. The UrQMD framework has been in use for nearly 20 years since its first development. In this period computing aspects, the design of code, and the efficiency of computation have been minor points of interest. Nowadays an additional issue arises due to ...

Although many-core architectures have emerged, it is unclear how these should be organized and programmed. We propose an architecture where programmable network interfaces ties processors, local memories, caches and the onchip interconnect together and provide basic primitives that allow for multiple simultaneous programming models.

This paper presents a system for automatically supporting the optimization of stencil kernels on emerging Non-Uniform Memory Access(NUMA) many-core architectures, through a combined compiler + runtime approach. In particular, we use a pragma-driven compiler to recognize the special structures and optimization needs of stencil computations and thereby to automatically generate low-level code tha...

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...
