On Wednesday, May 29, starting at 6 a.m. Eastern time, a database upgrade may make forms temporarily unavailable on the ARM and ASR websites. These include accounts, research highlights and publications, field campaigns, facility/help requests, and ARM data orders.


Request Access to the ARM Cluster


Is this an ARM infrastructure request?

Is this request for ARM development work as part of your ARM responsibilities? If yes, please fill out a Research Account Request.

If this request is related to a research project request, please continue to complete this form.


Who is making this request?

An active ARM user account is required for all requesters. If you do not have an account, please register here before continuing with your submission.

  • Enter your last name and click search
  • Select your name from the list that appears



An active ARM user account is required for all co-investigators. If your co-investigator does not have an account, please direct them to register here before continuing with your submission.

When do you intend to start/end work?

Project Title

Provide a brief title for the proposed research.

Project Description

Briefly describe the proposed research to be done using ARM computational resources—including specific scientific objectives. Briefly describe the relevance to ARM and justify the need for ARM high-performance computing (HPC) resources to meet the research objectives. Note that any request for ARM computational resources must include a clear use of ARM observational data and may include use of ARM modeling (e.g., LASSO) data.

Computational Approach

Provide a description of your proposed computational approach. The description may mention:

  1. Specific libraries required by the simulation and analysis software, algorithms and numerical techniques employed, programming languages, and other software used.
  2. Parallel programming model(s) used (e.g., MPI, OpenMP, Pthreads, CUDA, OpenACC).
  3. Project workflow and the availability of checkpoint and restart files.
  4. I/O requirements (e.g., amount, size, bandwidth, etc) for restart, analysis, and workflow. Highlight any exceptional I/O needs.
  5. ARM data: What ARM data do you anticipate using as part of this project? Please list all anticipated ARM data for this study.


Provide Software Package Names and URLs for each application software program proposed for use in your project. Indicate if the software is already on the ARM Cumulus cluster (view the list of currently available software). Information regarding instructions on obtaining source code for each program, restrictions and/or license requirements, if any, export control classification numbers (ECCN), and literature citations describing the application are appreciated.


Indicate the number of node hours needed.


Will you need staff assistance?
Hold Ctrl key to select multiple options.


Please let us know your data storage plans.
Consider the following regarding data storage and cleanup:

  • Estimate anticipated cumulative size of stored data at the end of the requested project.
  • What do you plan to do with the data at the end of the project?
  • Do you have tools and/or plans to reduce the data?
  • Please justify data storage needs exceeding 10 terabytes.
  • Describe planned publishable results and/or data.
  • Describe what final data products you would like to have archived and distributed from the ARM Data Center.

Non-ARM Data?

Will this project make use of non-ARM-funded data?


Principal investigators must review and agree to the ARM Code of Conduct when requesting to use high-performance computing resources. Please also read and accept the ARM computing, storage, cyber security, and reporting policies.

What happens after my request is approved?

Once a request is approved by ARM management, a notification will be sent to the designated requester with required steps to use the requested cluster. Please note that an Oak Ridge National Laboratory XCAMS account will be required. The Oak Ridge Leadership Computing Facility will contact you with additional steps.

Please refer any questions and feedback to the ARM Data Center Support Team.
