Compute Canada Database (CCDB) (FAQ)

Compute Canada, in partnership with regional organizations WestGrid, Compute Ontario, Calcul Québec and ACENET, leads the acceleration of research innovation by deploying state-of-the-art advanced research computing (ARC) systems, storage and software solutions. Together these partners provide essential ARC services and infrastructure for Canadian researchers and their collaborators in all academic and industrial sectors.

Compute Canada's world-class team of more than 200 experts, employed by 34 partner universities and research institutions across the country, provide direct support to research teams.

Compute Canada is a proud ambassador for Canadian excellence in ARC nationally and internationally.

There are two types of role:

  • sponsor roles (often referred to as Primary Investigators or PIs), and
  • sponsored roles.

Only faculty members can be sponsors. Administrators who are not faculty but who lead research projects must contact so that we can make appropriate accommodations. Faculty roles are only granted to faculty from Canadian post-secondary academic institutions who are eligible for CFI funding.

Sponsored roles fall into two groups:

  • internal, and
  • external.

The difference is in whether the applicant is part of the supervisors local group, or a collaborator from a different institution.

All students in the group should select the appropriate student position (undergraduate, masters, doctoral). Non-students should select the appropriate position from postdoctoral fellow, researcher (but only if the person is actually paid by the PI’s institution to work as part of the group—all other associates should apply as “External Collaborator”) or non-research staff (e.g. administrators, secretaries, etc.—people who do not typically need access to compute resources).

All collaborators who are not formally part of the PI’s group should apply as external collaborators. An external collaborators is anyone working with the group who the PI is willing to sponsor. Note however that external collaborators must specify an institution different from that of the PI. If they are eligible for another role corresponding to a different position then they should select that position instead.

Compute Canada DataBase. It is a database of researchers who wish to use the High Performance Computing facilities provided by Compute Canada Calcul Canada.

First, you will get an e-mail message with a link in it that you need to click on to confirm that the e-mail address you gave is valid. Next, someone will be sent an e-mail which asks them to approve your application. Everyone needs to be confirmed by someone. If you are a faculty member or non-research staff (typically consortium or Compute Canada staff) your application will be approved by consortium staff. Otherwise your application will be approved by the faculty member that you selected as your sponsor.

There are four regional consortia providing HPC resources in Canada. All are funded by the Canada Foundation for Innovation (CFI). The CFI expects the consortia to work together to provide researchers access to the computing power they need. To do this, and to make it easier for users to gain access to computing facilities across Canada, we have set up the CCDB. The CCDB website will provide one access point for all the Compute Canada facilities.

Before you can get an account at a regional HPC consortium, you must first sumbit a request for a Compute Canada Database (CCDB) account. Detailed instructions can be found on our Registering with the CCDB page.  

Once you have your CCDB login name and password, you can login to the CCDB website, click on "My Account" from the main navigation bar and from the dropdown menu that appears, select "Apply for a consortium account". There, you will find a list of the consortia with links to click on to get an account at that consortium. If you have any questions or difficulties finding this page, please contact

A CCI (Compute Canada Identifier) is a unique personal and national identifier. This is the identity you are required to bring to any of the regional HPC consortia when you apply for a local account. Your CCI is different from the local usernames given to you by the regional consortia. You can register for a CCI at

In order to register with the CCDB you either need to be a faculty member at a Canadian university or be sponsored by a faculty member at a Canadian university that is registered with the CCDB. People who can be sponsored include graduate students and research staff that report to the sponsoring faculty member.

A role is an identifier that represents the combination of a person’s position (eg. Faculty, Graduate Student, Postdoctoral Fellow, etc.), institution, and sponsor. In order to access Compute Canada resources one must have a valid and up-to-date role. A Compute Canada Role Identifier (CCRI) is associated with each role and uniquely identifies it. Most people will only have one role at a time, but when you change institution, sponsor, or position you will need to apply for a new role rather than update the old one. We ask you to do this so we can maintain accurate records for usage reporting to our governmental funding agencies.

Your CCRI is the unique identifier for your role (see “What is a Role?”). Since one person may have multiple roles over time, one CCI may be associated with more than one CCRI. Every job that runs on a Compute Canada HPC system is attributed to a CCRI.

RAP is short for Research Allocation Project. Researchers are usually working on at least one research project. For reporting purposes, we need to be able to provide statistics on how our facilities are used, but the word “project” is too ambiguous, therefore we use a name which does not have any implicit meanings. Also, computing resources are not allocated to individuals, they are allocated to groups of researchers. The RAP is the group of researchers which resources are allocated to. Most users will just have one RAP which gets a base allocation. Some researchers will have additional resource allocations, allocated to an additional RAP.

It is Compute Canada policy that each person only have one account (CCI). Requests for duplicate CCI’s are refused. If you have an existing CCI and have changed position you should apply for a new role (CCRI) instead. To do so, please log in with your existing account and visit the apply for a new role form. If you have forgotten your password, you may reset it . If you can no longer access the email address you have on file please email and we can update it for you.
