XF consists of a user interface, calculation engine, and supporting files, and must be installed on each laptop, desktop, or other machine that runs any of its software package components.
XF's user interface and calculation engine must have access to a license in order to run. Demo, node-locked, and USB key configurations utilize a license file, and a floating configuration uses a license server. Users should note that USB keys require additional setup.
XF's calculation engine utilizes NVIDIA graphics processing units (GPUs) upon proper installation. Instructions for installing the newest graphics-card driver, as well as answers to common questions, offer assistance throughout XF's setup process.
XF's calculation engine supports shared computing resources—both external and cloud-based. Users must configure their XF user interface once system administrators have configured the cluster. Individual simulations that utilize multiple machines require the installation of the message passing interface (MPI) on a compute cluster.
