.. _quotas: Quotas ====== Quotas enforce resource limits to users. A quota can be assigned to multiple users, but a user can have one quota. Quotas can be set on the following resources: * concurrent_executions : maximum number of concurrent executions in an active state * memory : maximum amount of memory a user can reserve in total, across all its active executions * cores : maximum amount of cores a user can reserve in total, across all its active executions * runtime_limit : maximum time an execution is permitted to run A default quota is always available: * name: default * concurrent executions: 5 * memory: 32GB * cores: 20 * runtime_limit: 24 hours This default quota can be modified, but not deleted. More quotas can be created via the zoe_admin.py command or the web interface.
