Abstract

We describe PFLOTRAN---a code for simulation of coupled hydro-thermal-chemical processes in variably saturated, non-isothermal, porous media---and the approaches we have employed to obtain scalable performance on some of the largest scale supercomputers in the world. We present detailed analyses of I/O and solver performance on Jaguar, the Cray XT5 at Oak Ridge National Laboratory, and Intrepid, the IBM BlueGene/P at Argonne National Laboratory, that have guided our choice of algorithms.
