Poster 68: Linking a Next-Gen Remap Library into a Long-Lived Production Code

Authors: Charles R. Ferenbaugh (Los Alamos National Laboratory), Brendan K. Krueger (Los Alamos National Laboratory)

Abstract: LANL's long-lived production application xRage contains a remapper capability that maps mesh fields from its native AMR mesh to the GEM mesh format used by some third-party libraries. The current remapper was implemented in a short timeframe and is challenging to maintain. Meanwhile, our next-generation code project has developed a modern remapping library Portage, and the xRage team wanted to link in Portage as an alternate mapper option. But the two codes are very different from each other, and connecting the two required us to deal with a number of challenges. This poster describes the codes, the challenges we worked through, current status, and some initial performance statistics.
