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.
