Planning spatial workflows to optimize grid performance

Luiz Meyer, James Annis, Mike Wilde, Marta Mattoso, Ian Foster
2006 Proceedings of the 2006 ACM symposium on Applied computing - SAC '06  
This work presents a generalized approach to planning spatial workflow schedules for Grid execution based on the spatial proximity of files and the spatial range of jobs.  ...  We show that, in initial tests on Grids of 5 to 25 sites, our spatial clustering approach eliminates 50% to 90% of the file transfers between Grid sites relative to the next-best planning algorithms we  ...  The thesis of this work is that spatial workflows can be best planned for Grid execution using spatially-aware scheduling algorithms; that such algorithms are simple to develop and deploy; and that such  ...

2021 Energy Science & Engineering  
Our exemplary concept exploits the capabilities of power system optimization, transmission network simulation, distribution grid planning, and agent-based simulation.  ...  Against this background, we introduce the so-called granularity gaps and discuss two possibilities to address them: increasing the resolutions of the established optimization models, and the different  ...  However, their validity is limited as they are subject to the actual state of the (transforming) power system. Disaggregation may also be performed by means of an optimization algorithm.  ...
