Gradient Networks
Zoltan Toroczkai, Balazs Kozma, Kevin E. Bassler +2
We define gradient networks as directed graphs formed by local gradients of a scalar field distributed on the nodes of a substrate network G. We derive an exact expression for the…
Virtual Time Horizon Control via Communication Network Design
Z. Toroczkai, G. Korniss, M. A. Novotny +1
We consider massively parallel discrete event simulations where the communication topology among the processing elements is a complex graph. In the case of regular topologies we re…
Suppressing Roughness of Virtual Times in Parallel Discrete-Event Simulations
G. Korniss, M. A. Novotny, H. Guclu +2
In a parallel discrete-event simulation (PDES) scheme, tasks are distributed among processing elements (PEs), whose progress is controlled by a synchronization scheme. For lattice…
Going through Rough Times: from Non-Equilibrium Surface Growth to Algorithmic Scalability
G. Korniss, M. A. Novotny, P. A. Rikvold +2
Efficient and faithful parallel simulation of large asynchronous systems is a challenging computational problem. It requires using the concept of local simulated times and a synchr…
Competing Populations in Flows with Chaotic Mixing
I. Scheuring, G. Karolyi, Z. Toroczkai +2
We investigate the effects of spatial heterogeneity on the coexistence of competing species in the case when the heterogeneity is dynamically generated by environmental flows with…
Epitaxial mounding in limited mobility models of surface growth
P. Punyindu, Z. Toroczkai, S. Das Sarma
We study, through large scale stochastic simulations using the noise reduction technique, a large number of simple nonequilibrium limited mobility solid-on-solid growth models. We…
