OpenPaths transportation planning software offers high-performance scientific, graphics and interactive computing capabilities. Certain OpenPaths features benefit from high-performance computing (CPUs) and dedicated graphics processors (GPUs). However, OpenPaths is developed for computationally efficient use of system resources and generally performs adequately even on modestly priced, conventional desktop computing systems.

Performance depends on model application and computing system, so we recommend users procure the fastest computing system reasonably available. OpenPaths performance is tied to many factors. In general, a system with better I/O performance, more RAM and faster, multiple processors cores will perform better. See details below.
