Partitions
Types of partitions/queues
In general, there are 2 categories of partitions (or queues) in the cluster.
- Community partitions
- Student – assigned to UG/PG students.
- Project – assigned to UG/PG students for their project assignments.
- researchlong – assigned to researchers, max run time of 5 days
- researchshort – assigned to researchers, max run time of 2 days.
- Priority partitions
- Priority - assigned to research teams who contributed their GPU nodes to the cluster.
Community partitions include GPU nodes from the priority partitions. Users using the community queues may face preemption. Priority partitions contains GPU nodes that are contributed by research teams (hence they are given priority access to it).
Job preemption refers to an event where your job is stopped to free up resources for other higher priority jobs to take place.
- Whenever there are insufficient resources, jobs in the community queue will be preempted first.
- If your job is running on one of the compute nodes contributed by a research team, your job may be pre-empted to free up resources for their research work.
Quality of Service (QOS)
To ensure that resource-demanding jobs on the cluster run smoothly, QOS are used to assign a quota on the amount of resource each account can request
In general, the QOS quotas are as follows:
| QOS | CPU cores | RAM (GB) | GPU | Max Job Runtime (days) |
|---|---|---|---|---|
| student | 4 | 16 | 1 | 1 |
| project | 30 | 30 | 1 | 1 |
| research-1-qos | 10 | 128GB | 2 | 5 |
| priority | Unlimited | Unlimited | Any | 5 |
