MSc (Elec Eng) Project
My MSc project was the development and testing of the parallelisation
of a Range-Doppler SAR processor. The inherent data parallelism found
in SAR data lead to the choice of using master slave parallel
processor, where copies of a slave task perform the same tasks on
different sets of data. However, the SAR processor that was
parallelised needed to implement a corner turn without saving data to
disk keeping the data set being processed distributed in memory over
the nodes in the cluster. This was successfully achieved using a
in-place method, thus saving valuable memory resources. Once the
parallel processor was implemented some timing tests where performed,
yeilding a maximum speedup factor of 6.2 for an 8 slave processor
system.
