摘要

I present a method for developing extensible and modular computational modelswithout sacrificing serial or parallel performance or source codereadability. By using a generic simulation cell method I show that it ispossible to combine several distinct computational models to run in the samecomputational grid without requiring modification of existing code. This isan advantage for the development and testing of, e.g., geoscientific softwareas each submodel can be developed and tested independently and subsequentlyused without modification in a more complex coupled program. Animplementation of the generic simulation cell method presented here, genericsimulation cell class (gensimcell), also includes support for parallelprogramming by allowing model developers to select which simulation variablesof, e.g., a domain-decomposed model to transfer between processes via a MessagePassing Interface (MPI) library. This allows the communication strategy of aprogram to be formalized by explicitly stating which variables must betransferred between processes for the correct functionality of each submodeland the entire program. The generic simulation cell class requires a C++compiler that supports a version of the language standardized in 2011(C++11). The code is available athref="https://github.comasailja/gensimcell"target="_blank">https://github.comasailja/gensimcell for everyone to use, study,modify and redistribute; those who do are kindly requested to acknowledgeand cite this work.
