Available Queues
Improv has several queues defined. Use the -q option with qsub to select a queue. The default queue is compute.
| Improv Queue Name | Description | Number of Nodes | CPU Type | Cores Per Node | Memory Per Node | Local Scratch Disk |
|---|---|---|---|---|---|---|
| compute | Standard Compute Nodes | 805 | 2x AMD EPYC 7713 64-Core Processor | 128 | 256 GB DDR4 | 960 GB (6 TB bigdata Nodes) |
| bigmem | Large Memory Compute Nodes | 12 | 2x AMD EPYC 7713 64-Core Processor | 128 | 1 TB DDR4 | 6 TB |
| debug | Reduced Walltime Compute Nodes | 8 | 2x AMD EPYC 7713 64-Core Processor | 128 | 256 GB DDR4 | 960 GB |
The compute queue has 68 nodes with a 6TB local NVMe scratch disk instead of the default 960GB NVMe.
File Storage
Users that do take advantage of local scratch space will have access to the shared GPFS file systems.
Please see our detailed description of the file storage used in LCRC here.
