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., compute nodes, 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.

Description

Storage/TB/year

$174.14

Effective July 1, 2020, the cost for one terabyte of HPC storage for a period of one year. For details on what the rate includes, see How to purchase storage.

Compute node

$9,336

The cost for one compute node, please see compute node specifications

Please refer to:

How to purchase storage

On the Hoffman2 Cluster users are endowed with 20GB of backed-up $HOME directories

To order dedicated storage for your group:


The IDRE Store uses the UCLA Federated Authentication Service to authenticate access, therefore you need to have a UCLA Logon ID 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.

Important

Please note that if you are using federal funds, these charges will incur facilities and administrative (F&A) 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 own priority use. Please refer to the Compute node specifications table to see the current standard node configuration.

To order compute node(s):

  • For standard compute nodes, open a ticket on our online help desk via this link and let us know the number of nodes you would like to purchase, one of the IDRE RTG technologists can work with you directly to discuss options.

  • For GPU nodes purchase, please submit a ticket via our this link and one of the IDRE RTG technologists can work with you directly to discuss options.

  • For memory upgrades, please submit a ticket via our this link and one of the IDRE RTG technologists can work with you directly to discuss options.

  • For larger disk capacities, please submit a ticket via our this link and one of the IDRE RTG technologists can work with you directly to discuss options.

Note

For a standard compute nodes purchase, once a node purchase agreement has been signed the node(s) is(are) generally assigned and available to your group within 2 business days.

Your purchase includes:

  • Full access to your cores through the Hoffman2 shared cluster queuing system

  • Administration of the group and users of your compute resources

  • Complete support of the hardware and the operating system

  • Connection to the cluster’s InfiniBand fabric

  • Access to IDRE RTG consultation services

  • Membership in the Hoffman2 Users Group (HUG)

  • Access to the software and compilers available on the cluster
