Title: Experiments at Scale with In-Situ Visualization Using ParaView/Catalyst in RAGE

Abstract

In this paper I describe some numerical experiments performed using the ParaView/Catalyst in-situ visualization infrastructure deployed in the Los Alamos RAGE radiation-hydrodynamics code to produce images from a running large scale 3D ICF simulation on the Cielo supercomputer at Los Alamos. The detailed procedures for the creation of the visualizations using ParaView/Catalyst are discussed and several images sequences from the ICF simulation problem produced with the in-situ method are presented. My impressions and conclusions concerning the use of the in-situ visualization method in RAGE are discussed.

  • A previous paper described some numerical experiments performed using the ParaView/Catalyst in-situ visualization infrastructure deployed in the Los Alamos RAGE radiation-hydrodynamics code to produce images from a running large scale 3D ICF simulation. One challenge of the in-situ approach apparent in these experiments was the difficulty of choosing parameters likes isosurface values for the visualizations to be produced from the running simulation without the benefit of prior knowledge of the simulation results and the resultant cost of recomputing in-situ generated images when parameters are chosen suboptimally. A proposed method of addressing this difficulty is to simply render multiple images atmore » runtime with a range of possible parameter values to produce a large database of images and to provide the user with a tool for managing the resulting database of imagery. Recently, ParaView/Catalyst has been extended to include such a capability via the so-called Cinema framework. Here I describe some initial experiments with the first delivery of Cinema and make some recommendations for future extensions of Cinema’s capabilities.« less

  • Post-processing and visualization are key components to understanding any simulation. Porting ParaView, a scalable visualization tool, to the Cray XT3 allows our analysts to leverage the same supercomputer they use for simulation to perform post-processing. Visualization tools traditionally rely on a variety of rendering, scripting, and networking resources; the challenge of running ParaView on the Lightweight Kernel is to provide and use the visualization and post-processing features in the absence of many OS resources. We have successfully accomplished this at Sandia National Laboratories and the Pittsburgh Supercomputing Center.

  • The Pittsburgh Energy Research Center of the Energy Research and Development Administration is studying catalytic methanation by conducting various experiments in a variety of different types of reactors. A summary is presented of three experiments involving a bench-scale tube wall reactor with flame-sprayed Raney nickel catalyst. Methanation was carried out at 300 psig, 340 and 380/sup 0/C with a feed gas of 3:1 H/sub 2/ to CO at 60J (60 standard cubic feet of feed gas per square foot catalyst area.) Tables and figures of experimental data along with calculated pertinent quantities are presented. The experimental data show a continuousmore » forward movement of the hot spot along the catalyst bed which may imply a temperature-induced deactivation. It was determined that a 1.9-2.2 inch catalyst length was required for near complete conversion for this reactor system and operating conditions. Although measured feed gas sulfur contents are low (less than 0.016 ppM), calculations of expected catalyst life estimates may warrant caution when disregarding sulfur as the poison for these reactor systems.« less
