It is time to renew your Compute Canada account again. Each year, there is a four-week renewal period in March and April when Compute Canada asks that all users renew their accounts. Note that standard accounts at the Centre for Advanced Computing require an active Compute Canada account to stay active. The deadline for renewal is April 23, 2018. Compute Canada accounts that have not been renewed by that time will be de-activated and have to be re-activated manually. Accounts with the Centre for Advanced Computing that are linked to inactive CC accounts will also be de-activated after this deadline. For details about Compute Canada Account Renewal, see https://www.computecanada.ca/research-portal/account-management/account-renewals ; for more information about the impact on CAC accounts, see https://cac.queensu.ca/wiki/index.php/Renewal
