Source Code Generation for Parallelized Simulations of Large-Scale Nonlinear Equation Systems on a Supercomputer using MOSAIC, PETSc, and ADOL-C

摘要

In this contribution, a flexible and free of charge framework for the parallelized solution of general nonlinear equation systems on a wide range of parallel platforms is presented. The new framework consists of a MOSAIC-based source code generator and a coupling library between the numerical libraries PETSc and ADOL-C. The functionality of the code generation as well as the coupling were tested using a nonequilibrium distillation column model. Thereby, a good speedup was observed on a Cray XC40 supercomputer with up to 96 cores in parallel.
