Reserve system time


This feature is available only to organizations that belong to the IBM Quantum™ Network(opens in a new tab).

Dedicated mode

Under standard operating conditions, IBM Quantum systems accept jobs according to the dynamic priority assigned by the fair-share queuing system.

Normal device queuing operation.

While this system attempts to balance workloads for the benefit of all users, there are often use cases where you may require limited-time access at a higher priority level. IBM Quantum provides an option to gain elevated access to specific systems over a specified period of time: Dedicated mode. Depending on your hub configuration, if you are a hub admin or group admin, you can reserve time in advance on a particular system with the Systems Reservations tool.

Example use cases for dedicated mode include the following:

  • In-class demonstrations
  • Iterative and near-time compute algorithms
  • Jobs involving detailed noise analysis
  • Time-critical projects
System reservations and fair-share allocation

System time accumulated while using system reservations counts toward an instance’s fair-share allocation amount.

If you need sole access to a specific quantum system for a given instance, select dedicated mode when making a reservation.

Dedicated mode with dedicated jobs.

Instance #2 in dedicated mode.

The standard fair-share queue is always blocked when the device is in dedicated mode.

Dedicated mode with no dedicated jobs leaves the device idle.

Dedicated mode with no dedicated jobs from instance #2 leaves the device idle.

This allows users to implement algorithms where input circuits are conditioned on previous results, such as iterative and near-time compute methods, without having to wait for other users’ results to process. If the dedicated instance has multiple users, then a single user’s jobs may be queued behind those of other users in the instance, as the execution is first-in first-out.
