Abstract

NG-TEPHRA, a project hosted by the PRAGMA community attempts to simulate in high detail ash deposition from volcanic activity. This topic has an ever increasing relevance, moreover in the light of recent geological events in Iceland. The simulation, specific to the Irazu volcano in Costa Rica, requires careful modeling and parameter selection for validation of hypotheses due to low-confidence input data, thus with high uncertainty. This paper explores the resulting structure of the parameter sweep that is being implemented in the NIMROD portal having the previously mentioned considerations in mind and analyzing its effect on the quality of the result. Further considerations regarding results handling within a largely distributed, homogeneous simulations are discussed and the current solution strategy is described.
