The New Reservation page contains a form for creating a new reservation.
Reservation Settings
Use this section of the form to specify information about and specifications for your reservation.
Name
Lets you specify the name of the reservation.
Description
Lets you specify a text description of the reservation.
Specifications
Lets you determine which of the following settings (if any) should be applied to the reservation. You may include as many or as few of these settings as you want.
| Setting | Description |
|---|---|
| Dedicated Resources | Specifies that no other tasks will take place on the server where this reservation exists. The reservation's resources will not be shared, regardless of whether or not the reservation is being actively used. |
| Ignore State | Specifies that the servers' states will not be considered in choosing which will contain the reservation. This means that the reservation could be assigned to a server that is down or active. This option can be useful for testing new servers. |
| Owner Preempt | Specifies that this reservation takes precedence over any other tasks assigned to the same server. Until your jobs on the reservation are complete, other users' jobs are put on hold. |
| Evacuate workload from selected nodes when the reservation starts | Specifies that you want to evacuate workload from reserved nodes before this reservation begins. This option will cause Moab to automatically evacuate VMs from this reservation's node list. |
Access Controls
In this section of the form, you can grant access to this reservation to Moab users, accounts, and groups. You can also specify the user, account, or groups' job affinity toward the reserved resources.
To add additional access controls to the reservation, choose Add (
). To remove access controls, choose Remove (
).
Lets you specify if the access setting applies to Moab user, group, or account. Choose one of the following:
| Option | Description |
|---|---|
| User | Specifies that the access control applies to a Moab user. |
| Account | Specifies that the access control applies to a Moab account. |
| Group | Specifies that the access control applies to a Moab group. |
For example:
Name
Depending on the Type, lets you specify the exact name of the Moab user, account, or group.
You must be careful to enter exact names or the users, accounts, and groups you specify will not be allowed access to the reservation.
Affinity
Lets you specify the Moab user, group, or account's affinity to the reservation. Choose one of the following:
| Option | Description |
|---|---|
| Positive | Specifies that the user, group, or account's jobs tend toward the reservation, causing the job to use the reservation's resources and leave other unreserved resources free for use by other jobs that may not have access to the reservation. |
| Negative | Specifies that the user, group, or account's jobs avoid the reservation. The reservation's resources are used only as a last resort. |
| Neutral | Specifies that the user, group, or account's jobs are neither attracted nor repelled by the reservation's resources. These jobs may or may not be given resources from the reservation. |
