Computational Credits

The NDA Computational Credits (CC) pilot program is aimed at providing an efficient model for scientists to request and receive approval for computational access into the NDA.  The model for the NDA awards – through Amazon Web Services (AWS) – credits that support compute resources and short-term data storage for specific research initiatives.  The resources are provided through the NIMH Data Archive, a federal system, and are to be used only in support of the approved research purpose. 

The requirements to be approved for CC are as follows:

  1. The researcher must be approved by for access to one of the NDA permission groups (e.g. ABCD, NDAR, NDCT, or RDoCdb).  Access to NDA permission groups requires sponsorship from an NIH recognized institution with an active Federal Wide Assurance on file with the United States Department of Health and Human Services, Office of Human Subjects Research Projections (OHRP). 
  2. The researcher and all colleagues are required to apply for CC.  The application must include; how the requested resources will enhance research discovery and the mission of the NDA, the requests potential contribution to science, the amount of initial funds needed, the amount of storage required, the services needed, and the number of simultaneous NDA AWS instances required.  Sufficient information is required in the request to allow for review and approval of CC and AWS accounts specific to the purpose requested. 
  3. Should the request be approved and CC provided, a required webinar will be scheduled, and once the webinar is completed, the AWS account specific to your needs will be created and provided to the requester(s).  All contributors must attend the webinar to receive accounts and access.

NDA Acceptable Use policy

The NDA Acceptable Use Policy includes the provisions of Amazon Web Services, provided by Amazon Web services (AWS) and will be follow the same policy for the accounts established. Please refer to  Additionally, the NDA has extended this policy to include the following terms:

  2. Monitored Activities – The NDA and the NIMH reserves the right to monitor all resource usage within the accounts provisioned. 
  3. Use of Accounts Provides – For each AWS account provided, only authorized users of the account will have access.  Furthermore, account holders will not create additional accounts or share their credentials with any other users unless expressly approved by the NIMH. 
  4. Duration and Amount of Support – The NIMH will provide access to AWS resources for a pre-determined period of time and for a pre-determined amount of funding support. It is be the responsibility of the applicant to keep track of the accounts provided, the space used, and resources consumed and ensure that all activities cease and data are cared for by the end of the approved period or when the account exhausts its spending limits. 
  5. AWS East Region – The accounts provided only permit resources to be used  within the AWS East Region.
