Execution of the SimSET Monte Carlo PET/SPECT Simulator in the Condor Distributed Computing Environment

K.G. Baum and M. Helguera (2007) Journal of Digital Imaging.

SimSET is a package for simulation of emission tomography data sets. Condor is a popular distributed computing environment. Simple C/C++ applications and shell scripts are presented which allow the execution of SimSET on the Condor environment. This is accomplished without any modification to SimSET by executing multiple instances and using its combine bin utility. This enables research facilities without dedicated parallel computing systems to utilize the idle cycles of desktop workstations in order to greatly reduce the run times of their SimSET simulations. The necessary steps to implement this approach in other environments are presented along with sample results.
