This survey is used to request -CSCS resources for the upcoming year. +A survey is sent out to subscribed users once per year, usually in the third quarter. It serves for collecting the CSCS resources requests for the upcoming year. Users registered in the **PSI HPC@CSCS mailing list** will -receive notification and details about the survey, in example: -* Link to the survey -* Update of resource changes -* Other details of the process +be contacted to take part in the yearly survey. Please [subscribe to the list](https://psilists.ethz.ch/sympa/subscribe/psi-hpc-at-cscs) if you are interested. -Generally users need to specify in the survey the total resources they intend to use -next year and also how they would like to split it over the 4 quarters (e.g. 25%, 25%, -25%, 25%).
