XFdtd consists of a user interface, calculation engine, and supporting files, and must be installed on each laptop, desktop, and compute machine that will run any of these 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, while 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 and answers to common questions offer assistance through XF's setup process.
XF's calculation engine supports shared compute resources—external and cloud-based. Users must configure their XF user interface once system administrators have configured the cluster. Individual simulations that utilize multiple compute resources necessitate the installation of the message passing interface (MPI) on a compute cluster.
