Account Renewals

This is a guide to the account renewal process at the Centre for Advanced Computing. It explains what you need to do in order to keep your account active. It also explains details of our present effort to bring our accounts up to date and synchronize the account structure with the one at Compute Canada.

How to renew an account at the Centre for Advanced Computing

Almost all accounts that entitle users to access to our Frontenac cluster require an active Compute Canada Role. The exception are temporary and teaching accounts. If you have a username starting with "hpc", you had to obtain Compute Canada credentials to obtain it. Compute Canada conducts annual renewals of their accounts/roles and will notify you with a deadline. Please follow those instructions. A separate renewal of your account at the Centre for Advanced Computing is not necessary as long as you keep the associated Compute Canada role active.

Please note that the converse is also true: If you let your Compute Canada role expire without renewing it, it will be deactivated. The CAC account that is associated with this role will also be de-activated and you will loose access to your CAC account.

Important: The next deadline for active Compute Canada accounts is April 30, 2018.
CAC accounts whose associated CCRI is not active after that date, will be de-activated.

If your account at the Centre for Advanced Computing is de-activated because you failed to renew or activate the associated Compute Canada role, you can re-activate it by contacting us at with a request for re-activation. However, you must supply us with an active CCRI from Compute Canada, which means that you have to renew your or re-activate your Compute Canada role first.

Account cleanup

In the spring of 2018, we are conducting a review of our accounts to bring them in line with Compute Canada's practice of regular renewals. We will contact users whose account is associated with inactive CCRI's with a request to participate in the annual Compute Canada account renewal to keep their accounts with us active.

Old accounts

Some of our users have accounts that are associated with Compute Canada roles that are not active anymore. In past years we have kept these accounts active unless a de-activation was requested or became necessary for other reasons. We cannot continue this practise, and will de-activate accounts that are found to be associated with inactive CCRI's after April 30, 2018.

If you are receiving an email to remind you to renew or re-activate your Compute Canada role to maintain an active account with the Centre for Advance Computing, please do so before the deadline set by Compute Canada for account renewal. We cannot make exceptions, as active accounts (roles) with Compute Canada are a pre-condition for an account with the CAC and are essential for proper accounting and usage reporting.

What if I don't have a Compute Canada account ?

In some rare cases, user may not have Compute Canada credentials. We will contact these users and direct them to apply for credentials. This is done through the Compute Canada Database Registration Page. Once you have obtained a CCRI (Compute Canada Role Identifier), please contact us at with that information, and we will link the role to your account. Make sure you apply for the right type of role: if you are a Principal Investigator (PI), apply for a role as faculty or another PI role; if you are "sponsored" by a PI, apply for one of the sponsored roles (student, post-doc, researcher, etc.) and provide the CCRI of your sponsor. It is important that this matches your account with us so we can link it.
