System Requirements

Simulations with openPASS are designed to be very lightweight and performant, without imposing huge requirements on the underlying hardware. Thus, openPASS simulations run as a single core application and do not utilize GPU. Only the build process during installation of openPASS makes use of multiple cores, so it is recommended to have at least a 4 core CPU. In the table below, minimal requirements are listed along with a commonly used, well working example setup.

System Specification	Minimal Requirements	Tested Setup (exemplarily)
Operating System	Windows or Linux (Debian Bookworm or Ubuntu 22.04 recommended)	Windows 10
CPU	Intel x64 Architecture with at least 1,50 GHz clock frequency	Intel i5-10310U
RAM	at least 8 GB	8 GB
GPU	not used by the simulation	Intel UHD Graphics 620
Others	1 GB free hard disk space
