Hydra Surveys and Stats#
Once a year we do a review of the usage of the cluster in the previous year. We carry out a user survey to gather feedback about your experience in our HPC clusters and collect usage data to analyse user activity on the clusters themselves.
The questions of the survey cover the full cycle of cluster usage, from getting access to the specific infrastructure needs of experienced users. The goal is to identify the weak and strong points in our scientific computing services as guidance for improvement in the future.
Our Overview for 2024 shows a very good satisfaction level of our users with the services provided by the SDC team. It also sheds light on some challenges and interesting trends for the future of the cluster.
All published reviews can be found in the survey list.
