Understanding your cluster usage costs How billing works Usage is tracked and billed per project. Costs are aggregated quarterly in an invoice, based on CPU/GPU hours, GB hours, storage, etc. You can view real-time and daily/weekly/monthly consumption on the billing dashboard (VPN connexion is required). Only the PI of the project can view its billing page. Other project members should contact their PI for usage/cost details. If unexpected charges are noticed, contact helpdesk@unil.ch, specifiying "DCSR" in the subject, before the end of the billing cycle (every quarter).
