QOS Specifications
The University of Alabama High-Performance Computing (UAHPC) infrastructure offers a range of Quality of Service (QoS) options and partitions designed to suit diverse computational requirements.
The primary “main” QoS allows a maximum of 1500 jobs per user, each with a 24-hour time limit. Although jobs within this QoS can utilize cluster resources, they are assigned lower priority compared to other QoS and partitions, notably the “owners” partition. This specific partition is dedicated to users who have acquired their nodes within the UAHPC cluster, granting them elevated priority and the ability to run their jobs continuously.
For those interested in expanding the cluster by purchasing nodes, detailed information can be found in our FAQ.
Additional QoS options encompass the “long” QoS, extending job duration to 1 week. Moreover, specialized nodes like high memory (“highmem”) and ultrahigh memory (“ultrahigh”) nodes cater to tasks requiring expanded memory resources.
The UAHPC configuration includes threaded QoS nodes optimized for individual thread usage, with a 48-hour time limit.
Furthermore, the “gpu” QoS provides access to 10 GPU nodes equipped with V100 and A100 NVIDIA GPU’s, delivering 173.3 TFLOPs of single-precision performance and up to 1316 TFLOPs for ML/DL applications.
QoS (rows) / Parition (columns) Limits on UAHPC
| QoS/Partition | Main | Long | Owners | Highmem | Ultrahigh | Threaded | GPU |
|---|---|---|---|---|---|---|---|
| Main | 24 hr / job 1500 jobs / group | X | 24 hr / job 1500 jobs / group | X | X | X | X |
| Long | 168 hr / job 309 cores / group | 168 hr / job 309 cores / group | X | X | X | X | X |
| Debug | 15 min / job 25 jobs / user | X | 15 min / job 25 jobs / user | 15 min / job 25 jobs / user | 15 min / job 25 jobs / user | X | X |
| Owners | X | X | a | a | a | X | X |
| Threaded | X | X | X | X | X | 48 hr / job 80 core/group 16 core/job 48 threads/job | X |
| GPU | X | X | X | X | X | X | 24 hr |
a CPU limits are dependent on user purchased hardware. Unlimited time. Preempts other jobs using long and main qos.
