Abstract:

This report presents the results of a HECToR dSCE project to a port a serial code modelling the magnetic properties of mineral systems to HECToR. The original project plan was to implement a semi-parallel code, using the Sundials CVODE library to perform the ODE solve in parallel, using a gather/scatter to transform between the serial parts of the code. This turned out to be impractical, and the PETSc library was adopted to develop a parallel version of the code instead. A bug was discovered in the PETSc - Sundials interface which meant a working parallel code could not be delivered. However, significant progress had already been made in developing the parallel code. Most of the remaining tasks required for a parallel code were supported by an Edikt project.
