Alpine Introduction and Orientation Part 2: Allocations and Queues

Allocations:

Allocations of time for high-performance computing (HPC) resources are based on Service Units (SU) and CPU core hours as follows:

1 SU = 1 CPU core-hour (i.e., a single fully utilized CPU core on 1 compute node for 1 hour)

New users:

All new HPC users will be added to the csu-general allocation, which amounts to about 40,000 SU/yr.

Batch Queues:

SLURM is the batch queuing system used on Alpine. For more information on batch queuing and job scheduling on Alpine, see the CU Boulder Research Computing User Guide.

For more information about using Alpine, see the CU Boulder Research Computing Tutorial Wiki.

Note that the CU examples will include information about how they log in to Alpine. Please substitute the information from our Remote login section.

FAQ:

How do I check my utilization of Service Units (SUs)?

You can check the utilization of service units that are being used

$ module load slurmtools
$ suuser Net_id@colostate.edu

Here the 21705 says that this amount of SU's are used.

How do I check the status of my submitted jobs?

To check the status of submitted jobs

$ module load slurmtols
