Advance Reservation Service (ARS)

The Advance Reservation Service (ARS) capability is available on all HPC systems within the HPCMP.
Quick facts:

  • ARS allows a user to reserve a block of time for their use on any system for which a user has an account.
  • A reservation can be made up to 25 minutes in advance of the requested time slot for up to 8 wall-clock hours of usage.
  • A reservation can be made up to 24 hours in advance of the requested time slot for more than 8 wall-clock hours of usage.
  • A reservation can be made up to 3 months in advance for a block of up to 168 wall-clock hours.
  • A single user can reserve up to 50% of ARS resources available on a system.
    • Typically, 25% of a system is available for ARS
  • Multiple jobs can be run within one reservation.
    • At the time of the reservation request, the user enters a valid project that has an allocation sufficient to address the reservation. However, when the user runs jobs during the ARS time period, the user may submit jobs with different projects.
    • The allocations for the projects that were used for each job will be charged — NOT the Project used during the ARS reservation request process.
    • Any unused time will be charged to the project indicated during the reservation request.
  • Multiple users are allowed to run within a reservation by reservation initiator at reservation request.
  • A single user can only have one reservation active at any time on a specific system.

An ARS User Guide is available on the User Dashboard.
