Run a job on a local fleet
Let the machines on one network take their tasks straight from each other, with machines elsewhere joining over a peer link.
Open ClustersBefore you start
- The machines are linked and in an HPC cluster. See Create a cluster.
- Every machine runs the OcaltQL Client.
Steps
- Open the cluster and find Network. Click Read the network. Machines on the same network are grouped as one island, with their local addresses. An island marked by address is a guess; after a run it says seen working directly.
- Submit a job as usual (see Split a job across machines), or open one you submitted.
- Click Run on the fleet. Clusters picks the hub: the online member with the most processors that is not a phone. Choose another under Hub if you prefer.
- Clusters sends the hub and worker programs, starts them, and connects each worker: Local network for workers on the hub's network, Peer link for the rest, and Through Ocalt when nothing more direct answers.
- Watch the run: each worker's tasks, its speed and how it is connected. Results come into the job as they arrive.
- Click Stop the fleet to end it early. When every task is done the hub and the workers stop on their own.
What happens next
A worker that goes offline does not lose work: the tasks it had taken go back to the queue after a short lease, and another worker runs them.
Good to know
- A fleet answers far faster than a task per command, so it suits jobs of many small tasks.
- A phone can be a worker; keep the OcaltQL Client open on it while the run lasts.
