*******************************
Purchasing additional resources
*******************************

The Hoffman2 Cluster is open, free of charge, to the entire UCLA campus with a base amount of computational and storage resources. Researchers can purchase additional computational and storage resources to increase their computational capacity and satisfy their storage needs. Computational resources (i.e., :term:`compute nodes`, :term:`GPU nodes`) owned by research groups can be accessed in preferential mode, in which each group accesses their own resources with higher priority and for extended run times, or in a shared mode, in which momentarily unused computational resources from each group are accessed by any other contributing group for short (up to 24 hours) run times. The advantage of shared model is that researchers can access a much wider set of resources than what they have contributed.

The :program:`IDRE Store` uses the UCLA Federated Authentication Service to authenticate access, therefore you need to have a `UCLA Logon ID <https://accounts.iam.ucla.edu/>`_ in order to access the site.  The UCLA Logon ID is not a service of the IDRE Research Technology Group, if you have difficulty with it consider contacting the `UCLA IT Support Center <https://www.it.ucla.edu/it-support-center/contact-us>`__.

.. important:: Please note that if you are using federal funds, these charges will incur facilities and administrative `(F&A) <https://ocga.research.ucla.edu/facilities-and-administrative/>`_ costs (56% as of July 1, 2018) as they are considered a service and not equipment.

Storage costs includes:

*    Backups
*    The physical storage space
*    The infrastructure to support it
*    Administration of the users of your storage space
*    Hardware and software upgrades
*    Problem fixes. 

This rate will remain in effect until renewed through the campus. 


How to purchase compute nodes
=============================

The Hoffman2 Cluster includes both a general campus use section, that is freely available to all interested researchers, and a condo-style section where researchers with significant computing needs can purchase and contribute nodes for their :ref:`own priority use <Group-owned nodes>`. Please refer to the :ref:`node-specs` table to see the current standard node configuration.
