The VACC is supported by a tiered, pay-per-use policy. All users of the VACC elect to join one of three tiers on a yearly basis. We also offer additional storage to users. The combined income from all paying users supports a full-time IT professional who facilitates our goals to expand and maintain the VACC. Currently, UVM provides financial support for hardware and maintenance.

All Memoranda of Understanding (MOUs) based on hardware purchased by VACC users are in effect. If you purchase dedicated hardware for the VACC, you are required join Tier 2 or Tier 3.

Payment arrangements are due by July 1st of each year.

Tier payment may change annually dependent on UVM internal funding commitment and grants awarded to the VACC.

Three Tiers

All three tiers enjoy full use of the VACC, with each tier being granted differing compute hours. Please see the table below for details.

3$4,060Over 100,000
1No cost to user**10,000

*Compute hours are calculated as: TIME  x  NUMBER OF CORES
**Subsidized by the Office of the Vice President for Research (OVPR)

Disk Storage per Tier

"Block" is the total size of your disk storage. "Files" is the total number of files allowed to be written to disk. For more information about filesystems and hard/soft limits, see Disk Quotas.


  • gpfs1 is backed up approximately 3 times a week.
  • gpfs2 is scratch space. It is not backed up.

Options for Funding

From an Existing Award

  1. Review current grant to determine if there is funding available.
  2. Contact granting organization for approval.
  3. Contact Andi Elledge for internal process and approval.

From a New Proposal

  1. When writing the budget, include a line item under ADP & Computing Services: F6020 (for account code 80047).
    FY21 Tier 2 is $1,015 and Tier 3 is $4,060.
  2. In the Budget Justification for the line item, supply the following text:
    Support is requested at (include amount) per year totaling (include amount) over the award period to provide high-performance computing services to the PI as part of the scope of this grant on behalf of UVM's Vermont Advanced Computing Center (VACC) cluster services. (*ONE SPECIFIC SENTENCE ABOUT THIS GRANT AS TO THE COMPUTATIONAL NEEDS*) The VACC is a multi-thousand core “big compute” Linux cluster, with hundreds of terabytes of GPFS storage. This service will help the PI and their students compile, deploy, store and retrieve the computational components of the proposed work. Additionally, the VACC will provide the required training for the PI and their students including system documentation. As part of the service an IT technician will aid with the selection and implementation of any system upgrades and software installations required for the proposed work.
  3. For the Facilities, Equipment, and Other Resources section of the proposal you can use VACC cluster specs.

Internal transfer of funds

If you have internal funding, such as research incentive funds or a start-up account, please contact Andi Elledge at and she will work with your department business manager to transfer the funds for your use.

VACC Voucher Fund

The Office of the Vice President for Research will issue a voucher to support faculty interested in advancing their research or teaching by incorporating computational and research support services from the Vermont Advanced Computing Center. This funding is to support UVM faculty with computational needs that do not currently have grants or internal departmental funding that supports VACC use.

Example Voucher Qualifications:

  • New hires - to support the Deans in their efforts to attract researchers to UVM.
  • Faculty that are moving existing research from personal computers to high-performance computing and need help with advanced coding.
  • Users interested in employing machine learning in future research but have minimal previous experience with HPC and are unable to transition their scientific workflows to GPUs (i.e. DeepGreen) without help.
  • Faculty that require computational results to submit a grant or advice and support for proposal development related to high-performance computing and machine learning.
  • Faculty interested in providing access to cyberinfrastructure resources and services to students to support teaching across all fields.

Voucher amount is up to $10,000 and will include priority cluster access and services.  Vouchers must be used prior to June 30, 2021 and cannot be carried over into additional years.
