Parallel network simulations with NEURON

Henry Markram

The NEURON simulation environment has been extended to support parallel network simulations. Each processor integrates the equations for its subnet over an interval equal to the minimum (interprocessor) presynaptic spike generation to postsynaptic spike de ...

Can a Helmholtz solver run on a cluster?

Marc Anthony David Habisreutinger, Emmanuel Leriche, Vincent Keller

Our vectorized Helmholtz solver runs at 85% efficiency on a NEC SX-5. The most time-consuming parts have been ported on SMP, NUMA, and cluster architectures. It is shown that an OpenMP version can deliver similar performance when running it on a 16 process ...

Fault-tolerant parallel applications with dynamic parallel schedules: a programmer's perspective

Roger Hersch, Sebastian Gerlach

Dynamic parallel schedules (DPS) is a flow graph based framework for developing parallel applications on clusters of workstations. The DPS flow graph execution model enables automatic pipelined parallel execution of applications. DPS supports graceful degr ...

Fault-tolerant parallel applications with dynamic parallel schedules

Roger Hersch, Sebastian Gerlach

Commodity computer clusters are often composed of hundreds of computing nodes. These generally off-the-shelf systems are not designed for high reliability. Node failures therefore drive the MTBF of such clusters to unacceptable levels. The software framewo ...

OnCall: defeating spikes with a free-market application cluster

George Candea

Even with reasonable overprovisioning, today's Internet application clusters are unable to handle major traffic spikes and flash crowds. As an alternative to fixed-size, dedicated clusters, we propose a dynamically-shared application cluster model based on ...

SMARTS: accelerating microarchitecture simulation via rigorous statistical sampling

Babak Falsafi

Current software-based microarchitecture simulators are many orders of magnitude slower than the hardware they simulate. Hence, most microarchitecture design studies draw their conclusions from drastically truncated benchmark simulations that are often ina ...

Hybrid QM/MM Car-Parrinello simulations of catalytic and enzymatic reactions

Ursula Röthlisberger, Maria Carola Colombo, Leonardo Guidoni

A review. First-principles mol. dynamics (Car-Parrinello) simulations based on d. functional theory have emerged as a powerful tool for the study of phys., chem. and biol. systems. At present, using parallel computers, systems of a few hundreds of atoms ca ...

Parallel DEM Simulations of Granular Materials

Thomas Liebling, Jean-Albert Ferrez

Computer simulations of granular materials are often based on the Distinct Element Method (DEM) where each grain is considered individually. Since large quantities of grains are required to perform realistic experiments, high performance computing is manda ...

Integrating behavioural animation techniques

Daniel Thalmann, Jean-Sébastien Monzani

Our research focuses on animating autonomous virtual humans which are able to take decisions by themselves. We especially address in this paper the technical problem of integrating altogether the physical simulation of agents (represented as virtual humans ...

Wisconsin Wind Tunnel II: a fast, portable parallel architecture simulator

Babak Falsafi, James Richard Larus, David Wood

To analyze new, parallel computers, developers must rapidly simulate designs running realistic workloads. Historically, direct execution and a parallel host have accelerated simulations, although these techniques have typically lacked portability. Through ...
