dc.description.abstractThe graphical user interface (GUI) of COMSOL Multiphysics offers an effective environment to get started solving problems. For reproducibility of the results, it is often desirable to explore the script-based modeling capabilities of COMSOL with MATLAB. There are also potential benefits of running COMSOL in parallel, specifically by running several computational threads in shared-memory parallelism mode. We use the scripting abilities of COMSOL with MATLAB to study the shared-memory parallel performance of COMSOL, that is, the solution time required by using multi-threading on one multiprocessor, multi-core computer with shared memory among the processors. The performance results show that using more than one thread saves time, but the speedup is not in proportion to the number of cores useden_US
dc.description.sponsorshipThe authors would like to thank Samuel Trahan for his assistance and for contacting COMSOL support and obtaining the con rmation that COMSOL does not run in full distributed memory parallel mode. The hardware used in the computational studies is part of the UMBC High Performance Computing Facility (HPCF). The facility is supported by the U.S. National Science Foundation through the MRI program (grant no. CNS{0821258) and the SCREMS program (grant no. DMS-0821311), with additional substantial support from the University of Maryland, Baltimore County (UMBC). See www.umbc.edu/hpcf for more information on HPCF and the projects using its resources.en_US
