Clusters of conventional computers have almost replaced vector-based supercomputers among the world9s 500 biggest computing complexes, thereby tapping a computing resource with lower costs. But as Kirkpatrick explains in his Perspective, this approach brings new problems. He highlights the report by Korniss et al ., who demonstrate that the simulations times of the different processors can diverge very quickly, leading to temporal "roughening." As a result, it can be difficult to synchronize… Expand
Translating network models to parallel hardware in NEURON
TLDR
Here it is shown how to make this transition for models implemented with NEURON, in such a way that the final result will run and produce numerically identical results on either serial or parallel hardware. Expand
Small-World Synchronized Computing Networks for Scalable Parallel Discrete-Event Simulations
We study the scalability of parallel discrete-event simulations for arbitrary short-range interacting systems with asynchronous dynamics. When the synchroniza- tion topology mimics that of theExpand
Extreme fluctuations in noisy task-completion landscapes on scale-free networks.
TLDR
This work presents large-scale simulation results using the exact algorithmic rules, supported by mean-field arguments based on a coarse-grained description, of extreme fluctuations in noisy task-completion landscapes, such as those emerging in synchronized distributed-computing networks, or generic causally constrained queuing networks, with scale-free topology.

Synchronization landscapes in small-world-connected computer networks.
TLDR
A simple growth model on regular and small-world networks, embedded in one and two dimensions, finds that the synchronization landscape exhibits Kardar-Parisi-Zhang-like kinetic roughening on regular networks with short-range communication links. Expand

TLDR
It is found that in the mean-field approximation on uncorrelated scale-free graphs, synchronization is optimal at beta*= -1 and the naturally related problem of optimizing performance in queue-limited communication networks utilizing local weighted routing schemes is pursued. Expand

Optimizing Synchronization, Flow, and Robustness in Weighted Complex Networks
TLDR
This chapter investigates optimization in fundamental synchronization and flow problems where the weights are proportional to (k i k j )β with k i and k j being the degrees of the nodes connected by the edge. Expand

We study the effective resistance of small-world resistor networks. Utilizing recent analytic results for the propagator of the Edwards–Wilkinson process on small-world networks, we obtain theExpand

Suppressing Roughness of Virtual Times in Parallel Discrete-Event Simulations
TLDR
It is shown that weak random interactions among thePEs can make this spread nondivergent, and the PEs then progress at a nonzero, near-uniform rate without requiring global synchronizations. Expand

Dynamic scaling of growing interfaces.
TLDR
A model is proposed for the evolution of the profile of a growing interface that exhibits nontrivial relaxation patterns, and the exact dynamic scaling form obtained for a one-dimensional interface is in excellent agreement with previous numerical simulations. Expand
