Attention: Due to an upgrade beginning on Friday, the 22nd August 2025, any new collabs, groups and any changes to teams will not be kept beyond the weekend. User creation will also be disabled during this time. The actual upgrade will take place on Wednesday, 27th August. On that day, any service requiring a Keycloak login will be unavailable for the duration of the upgrade. Thank you for your understanding as we complete this important work.

For the duration of the maintenance period, Collaboration and Group creation features will be temporarily disabled and will return HTTP 503 Service Unavailable errors until further notice.

11 +The call to //client.list_resource_requests(repoInfo.nameInTheUrl)// in the batch-exmaple notebooks currently (19 August 2022) result in a "504 Gateway Time-out" error due to a problem in the back-end. As a workaround, please just skip the part by inserting a line with the content

42 -Via choosing a different lab execution site it is be possible to choose a specific site, if there are specific needs for the created Jupyter virtual machine for a given task (e.g. a large memory requirement). Currently all the examples do not need any site specific features, so you can select in principle any site. The "safe choice" is to use CSCS as the primary execution site.
