-The computational resources of IT4I are allocated by the Allocation Committee to a Project, investigated by a Primary Investigator. By allocating the computational resources, the Allocation Committee is authorizing the PI to access and use the clusters. The PI may decide to authorize a number of her/his Collaborators to access and use the clusters, to consume the resources allocated to her/his Project. These collaborators will be associated to the Project. The Figure below is depicting the authorization chain:

-Head of Supercomputing Services acts as a PI of a project DD-13-5. Joining this project, you may **access and explore the clusters**, use software, development environment and computers via the qexp and qfree queues. You may use these resources for own education/research, no paperwork is required. The DD-13-5 project is not intended for production calculations, in such a case please apply for own project.  All IT4I employees may contact the Head of Supercomputing Services in order to obtain **free access to the clusters**.
