Choose a host mode

A host mode states when a machine may accept AmpleRun work and when it must step aside. It is an availability policy, not a stronger hardware-isolation boundary or a promise of continuous earnings.

Mode	Intended use	Renter implication
dedicated	Capacity allocated to AmpleRun rather than competing local rental workloads	Read the offer’s actual availability terms
idle	A personal machine that offers eligible capacity while the owner is away	Offered as Interruptible
colisted	Capacity also offered through another platform	Offered as Interruptible and withdrawn while competing work is detected

Idle and Co-listed are useful when reclaiming the machine is part of normal operation. They are not a way to hide that interruption risk from renters.

Select deliberately

The Linux installer accepts a mode flag, for example:

sudo bash amplerun-host.sh --json --mode colisted

Use only the mode that describes how you actually operate the machine. The host agent’s checks can block a dedicated installation when another platform or foreign tenant is detected. Do not disable the other service or conceal the workload merely to pass a check.

Mode availability can depend on the tier and installer path. Follow the current installer’s output and the host console rather than applying Linux service instructions to a macOS user-service install.

Read interruption terms as a renter

A quote includes availability_class and preemption_notice_s. It may include a sample-gated interruption estimate. A missing estimate means there is insufficient evidence to show one; it does not mean zero interruption risk.

For Interruptible work, checkpoint progress and save output outside the rented machine. Do not place the only copy of an important result inside a workload that may be reclaimed. Select a different availability class when the task cannot tolerate interruption.

Before maintenance, stop accepting new work and inspect active rentals in the host console. A change to an availability policy is not evidence that an active job has already stopped.
