2012 Proceedings of the 26th ACM international conference on Supercomputing - ICS '12  
Load balance is critical for performance in large parallel applications.  ...  Some strategies place the burden of providing accurate load information, including the decision on when to balance, on the application.  ...  For example, one might expect the cost of a global balanc-ing scheme to be higher than that of a diffusive algorithm at scale because the time required for an immediate rebalance outweighs the amortized  ...

2007 arXiv   pre-print
cooperativity and/or large diffusion coefficient, i.e.  ...  In order to explain the observed anomalous diffusion, we have to seek for the mechanism that should allow both the amplitude and the time scale of the velocity correlation to be independent of the filament  ...  In the case with load, the large value of the correlation does not give a large value of D; This means that the back and forth movement in short time scale does not give net motion, and the diffusion comes  ...

Experimental and Modeling Analysis of Graphite Electrodes with Various Thicknesses and Porosities for High-Energy-Density Li-Ion Batteries

Simon Malifarge, Bruno Delobel, Charles Delacourt
2018 Journal of the Electrochemical Society  
However, high-loading electrodes undergo large liquid-phase limitations at medium to high current densities: a large overpotential develops because of the formation of a large salt concentration gradient  ...  It emerges that low-loading electrodes suffer from larger particle-scale limitations (mainly solid-diffusion limitation) than high-loading electrodes because of a lower active surface area per geometric  ...  Malifarge is grateful to ANRT for partially supporting the funding of this research work.

Dev Niyogi, Hsin-I Chang, Fei Chen, Lianhong Gu, Anil Kumar, Surabi Menon, Roger A. Pielke
2007 Natural Hazards  
The results of this study suggest that the large magnitude of aerosol loading and its impact on land-atmosphere interactions can significantly influence the mesoscale monsoonal characteristics in the Indo-Ganges  ...  In this paper, we propose that another pathway by which aerosols can modulate the multi-scale aspect of Indian monsoons is by altering the land-atmosphere interactions.  ...  Therefore, changes in the diffuse radiation fraction as a result of aerosol loading would appear to have the potential to have an impact on the efficiency of land-atmosphere interactions.  ...
