Multicore Aware Parallel Simulations of CO2 Geological Storage

Abstract : We enhance the parallel scalability of the general-purpose Tough2-MP code to consider complex modeling. This talk will focus and the required adaptations of the assembly and the solve phases considering the impact of the mapping of the processes on the physical cores. We will also comment on the extra-costs inferred by the memory hierarchy and the bandwidth limitation. Some illustrative examples of long-term fate of CO2 stored in reservoirs will also be detailed.
