GPGPU Accelerated Parallel and Fast Simulation of Thousand-core Platforms.

David Atienza Alonso, Luca Benini, Martino Ruggiero, Shivani Raghav

Future architectures will feature hundreds to thousands of simple processors and on-chip memories connected through a network-on-chip. Architectural simulators will remain primary tools for design space exploration, performance (and power) evaluation of th ...

Sampling and Reconstructing Diffusion Fields with Localized Sources

Martin Vetterli, Yue Lu, Juri Ranieri, Amina Chebira

We study the spatiotemporal sampling of a diffusion field generated by K point sources, aiming to fully reconstruct the unknown initial field distribution from the sample measurements. The sampling operator in our problem can be described by a matrix deriv ...

Realistic Modeling of 3D Plasmonic Systems

Andreas Kern

Interest in plasmonic nanostructures has recently multiplied due to their extraordinary optical properties. When resonantly excited, these tiny metallic systems exhibit a strong and localized optical field enhancement. Applications exploiting this effect e ...

Feed forward in the LHC

Xavier Buffat, Jorg Wenninger

The LHC operational cycle is comprised of several phases such as the ramp, the squeeze and stable beams. During the ramp and squeeze in particular, it has been ob- served that the behaviour of key LHC beam parameters such as tune, orbit and chromaticity is ...

Simulating real DSP code using a DLL, application to a 3-level VSI SVC

Jean-Jacques Simond, André Hodder, Roland Wetter, György Atilla Bànyai

The present paper addresses the use of a Windows™ DLL to simulate the real code of a DSP for faster development time and advanced testing, especially in high power systems. The development of power system control usually starts with simulations and the dev ...

ProtoFlex: Towards Scalable, Full-System Multiprocessor Simulations Using FPGAs

Babak Falsafi

Functional full-system simulators are powerful and versatile research tools for accelerating architectural exploration and advanced software development. Their main shortcoming is limited throughput when simulating large multiprocessor systems with hundred ...

Comparison of Methods for Increasing the Performance of a DUA Computation

Computing realistic routes for a given road network and a known demand of vehicles is one of the most important steps when preparing a road traffic simulation. The approach developed by Christian Gawron in 1998 which we use for this purpose computes a dyna ...

Simulation sampling with live-points

Babak Falsafi

Current simulation-sampling techniques construct accurate model state for each measurement by continuously warming large microarchitectural structures (e.g., caches and the branch predictor) while functionally simulating the billions of instructions betwee ...
