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:
!!! Note "Note"
!!! note
You need to either [become the PI](../applying-for-resources/) or [be named as a collaborator](obtaining-login-credentials/#authorization-by-web) by a PI in order to access and use the clusters.
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. All IT4I employees may contact the Head of Supercomputing Services in order to obtain **free access to the clusters**.

Authorization by e-mail (an alternative approach)
-------------------------------------------------
In order to authorize a Collaborator to utilize the allocated resources, the PI should contact the [IT4I support](https://support.it4i.cz/rt/)(E-mail:[support[at]it4i.cz](mailto:support@it4i.cz)) and provide following information:
1. Identify your project by project ID
2. Provide list of people, including himself, who are authorized to use the resources allocated to the project. The list must include full name, e-mail and affiliation. Provide usernames as well, if collaborator login access already exists on the IT4I systems.
3. Include "Authorization to IT4Innovations" into the subject line.
