Frequently Asked Questions about the CCDB
CCDB basics[edit]
What does CCDB stand for?[edit]
Compute Canada DataBase. It is a database of researchers who wish to use the Advanced Research Computing (ARC) facilities provided by Compute Canada.
What is the purpose of the CCDB?[edit]
There are six consortia providing ARC facilities in Canada. All are funded by the Canada Foundation for Innovation (CFI). 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 web site provides one access point for all the Compute Canada Federation facilities.
What can I do on the portal?[edit]
- register
- manage personal information and roles
- link to consortium sites to apply for accounts
- apply for the Resource Allocations Competitions (RAC)
- manage RAP information and membership
What is a CCI and why would I want one?[edit]
A Compute Canada Identifier (CCI) is a unique personal and national identifier. This is the identity you are required to bring to any of the regional ARC consortia when you apply for a local account. Your CCI is different from the local usernames given to you by the regional consortia. When you register at https://ccdb.computecanada.ca a CCI is created for you.
Who is eligible to get a CCI?[edit]
In order to register with the CCDB you must
- be a faculty member at a Canadian institution that is registered with the CCDB, or
- be sponsored by a faculty member at a Canadian institution that is registered with the CCDB.
People who can be sponsored include, but is not limited to, graduate students and research staff that report to the sponsoring faculty member.
What is a role?[edit]
A role is an identifier that represents the combination of a person's position (e.g., 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.
What is a CCRI?[edit]
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 ARC system is attributed to a CCRI.
What is a RAP?[edit]
Compute Canada resources are made available to PIs through Resource Allocation Projects (RAP). 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.
In general, there are two main types to RAPs:
- Default RAP: A default RAP is automatically created when a PI role is activated. Default and Rapid Access Service quotas for storage and cloud resources are managed via this default RAP. The Default RAP allows PIs and sponsored users to make opportunistic user of compute resources with with default (that is, the lowest) priority. On CCDB, it uses the convention def-username [username is also known as "local account").
- RAC RAP: This RAP is created when the PI receives an award through any of the Resource Allocation Competitions. On CCDB, it uses the convention rrg-username-xx or rpp-username-xx, depending on the competition.
How to manage RAP membership?[edit]
The PI must add sponsored users to a RAP in order for them to access CC resources. PIs can manage RAP memberships at any time on CCDB by adding, removing and assigning roles to sponsored users. There are three RAP membership roles:
- Owner: by default, the PI is the sole owner of the RAP and all the allocations associated to that RAP. This cannot be changed. The Owner can add or remove RAP managers and members.
- Manager: the PI can give Manager permissions to any sponsored user of a default or RAC project, or any sponsored user or co-PI of a RAC project. Managers can add or remove RAP managers and members.
- Member: the PI can add any sponsor user as a member of a default project. Sponsored users and co-PI can also be added as members of a RAC project.
RAP membership is represented as a group in LDAP. It defines a group of users that are authorized to submit jobs against the RAPI (which is the Id of the RAP) and share files within the same Unix group.
Registering for an account[edit]
I had an account in the past, but my position or sponsor has changed or I have lost my password. Should I sign up for a new one?[edit]
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 accounts@computecanada.ca and we can update it for you.
How do I sign up?[edit]
Go to the register link. Note that you will have to accept the following policies and agreements to get an account:
- Terms of Use [1]
- Privacy and data protection policy [2]
- Consent to Collect, Use and Disclose Personal Information
What position do I select when applying for a role?[edit]
There are two main types of roles:
- 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 accounts@computecanada.ca 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.
What happens after I submit my request?[edit]
You will receive an e-mail with a link to confirm the e-mail address you provided. If you are a principal investigator (typically, a faculty member), your application will be approved by consortium staff. Otherwise your application will need to be confirmed by the principal investigator you identified as your sponsor before it is approved by consortium staff.
How do I get an account at a consortium?[edit]
Click on Local Accounts and it will give you a list of the consortia with links to click on to get an account at that consortium. Note that consortium or local accounts are needed only to log in to our legacy systems. Users can log in to any of the new national systems with their Compute Canada credentials.
