Users often ask about why their job that should only take few seconds spend far longer in the "in progress" state. Some would even take the drastic step of canceling these jobs, fearing they'd be spending too much.
The docs on execution mode talk briefly about parallel classical processing, but it doesn't talk about QPU contention at all. We should add a section or a page explaining that:
- Each job needs to go through classical pre-processing before running on the QPU
- A job transitions to "in progress" status on IQP ("running" in Qiskit) as soon as its classical processing starts
- Most of the classical processing can be done in parallel, which is why multiple jobs can enter the "in progress" status simultaneously
- However, only one job can run on the QPU at a time. Hence QPU contention could happen if multiple jobs have gone through pre-processing and are ready for the QPU. If there is high QPU contention, a job can remain in "in-progress" state for longer than expected.
- Both the estimated usage and maximum execution time are based on the time the QPU is locked to execute the job and therefore exclude multi-threaded classical processing.
