More information on: - `AlmaLinux OS <https://almalinux.org/>`_ .. - `RHEL9 oficial documentation <https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/9.2_release_notes/index>`_ The hardware nodes of the infrastructure are divided in three classes: - User Interfaces (UI) : the entry point for users, provide a working environment where to compile and test their programs. When the jobs are ready, users can submit their production batch jobs with Job Management System to the Worker Nodes. .. - Worker Nodes (WN): where the production user jobs are executed. .. - Storage Nodes(SN): disk servers to store user and project data. All the nodes of GRAVITON are connected throught Infiniband Network (200 GBE) .. list-table:: :align: center :widths: 25 25 25 25 25 25 25 25 25 :header-rows: 1 * - Name - Role - N\.
