This feature is available only to organizations that belong to the IBM Quantum™ Network(opens in a new tab). Educators and researchers can also make reservations and access other benefits by signing up for one of the special programs we offer. Go to the Educators program sign-up form(opens in a new tab) or the Researchers program sign-up form(opens in a new tab) for more information.
Under standard operating conditions, IBM Quantum systems accept jobs according to the dynamic priority assigned by the fair-share queuing system.
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 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 (only available to members of the IBM Quantum Network(opens in a new tab)).
The standard fair-share queue is always blocked when the device is in dedicated mode.
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.
