Manage nodes

Reserve GPU nodes for a team, change or clear a reservation, and check rack inventory in the CosmicAC web interface.

Reserve GPU nodes for a team so that the team's new jobs run only on those nodes. Manage reservations in Settings > Nodes.

Prerequisites

You need the following before you start:

How reservations work

  • A team with reserved nodes runs its new jobs only on those nodes.
  • A team without a reservation uses the nodes that no team has reserved.
  • If the Unreserved nodes card at the top of the Nodes page shows Blocked, a team without a reservation can't run jobs.
  • Only one team can reserve a node at a time.

Open the nodes page

  1. In the sidebar, click Settings.
  2. In the Instance group, click Nodes.

The Reservations tab lists the teams that have reserved nodes. The Inventory tab lists every node that an online rack reports, with its rack, GPU type, free GPUs, and the team that reserved it.

Reserve nodes for a team

  1. On the Nodes page, click Reserve nodes.
  2. In the Team list, select the team.
  3. Select the nodes to reserve. You can't select a node that shows Held by, because another team already holds it.
  4. Click Save changes.

A Nodes updated message confirms the reservation.

You can also manage a team's reservation from Settings > Teams. In the team's row, click Manage nodes.

Change a team's reservation

  1. On the Reservations tab, click the team's row.
  2. Select the nodes to add and clear the nodes to release.
  3. Click Save changes.

To undo your changes before you save them, click Discard.

To release all nodes, clear every selected node, and then click Release all nodes. In the confirmation dialog, click Release all nodes.

Clear a team's reservation

  1. On the Reservations tab, in the team's row, open the menu.
  2. Click Clear reservation.
  3. In the Clear reservation dialog, click Clear reservation.

Help and troubleshooting

Saving fails because another team already holds a selected node

Only one team can reserve a node at a time. Release the node from the other team's reservation first, and then reserve it for this team.
