Compute Reservation Request Form

Users can request a scheduled reservation of machine resources if their jobs have special needs that cannot be accommodated through the regular batch system. A reservation brings some portion of the machine to a specific user or project for an agreed upon duration. Typically this is used for interactive debugging at scale or real time processing linked to some experiment or event. It is not intended to be used to guarantee fast throughput for production runs.

For normal batch jobs, charging against a project's allocation is done on a per job basis. For scheduled reservations the entire block of reserved time is charged regardless of the number of nodes used or time spent running jobs. Cancellation of a reservation must be done with a minimum of 72 hours notice.

Please ask for the least amount of resources you need and try to schedule reservations so as to minimize impact on other users. For instance, scheduling a reservation just after a scheduled downtime will reduce idle time while the system waits for the requested nodes to be freed. Also, if you have multiple reservations, it's most efficient to bundle them together in close succession.
