BOINC (Berkeley Open Infrastructure for Network Computing) is an open-source framework for solving large-scale and complex computational problems by means of public resource computing (PRC). In contrast to massive parallel computing, PRC applications are distributed onto a large number of heterogeneous client computers connected by the Internet where each computer is assigned an individual task that can be solved independently without the need of communication upon the clients. This generally restricts the usability of PRC; however, nowadays even small companies hold remarkable computer resources which are not accessible as a whole but distributed over the numerous computers which belong to the standard working environment in today's companies. Over the day, these computers are rarely operating at full capacity and hence valuable computational power is just wasted. Here, we present a new approach for performing large-scale parameter studies using COMSOL Multiphysics based on the BOINC technology which can be used to utilize idle computer resources that are connected within a companywide intranet. The only requirement for using these resources is that COMSOL Multiphysics is installed on each machine. Based on our approach we provide a tool and a user interface, respectively that allows the COMSOL Multiphysics user to define a high-level description of the parameter study that needs to be performed. The tool then automatically performs, monitors, and optimizes the complete parameter study using the existing computer resources.
