h1. Common Queue Names

{tip}
Common queue names will allow users to understand LinkSCEEM-2 HPC environment faster and move scripts across sites more easily.

{tip}

A goal of this policy is to institute a core namespace of batch queues with the same names at each of the centers participating in the Baseline Configuration Initiative. The queue names were chosen to align with LS2 project priorities. In addition, each center is explicitly allowed to offer customized batch support and service levels for specialized work loads of each own.

The core set of common queue names will allow users to more easily move their jobs and scripts among centers. This improves user productivity by requiring less time and effort to support many different scripts and to learn a different queue environment at each center.

The Compute queue names defined by this project and their respective priority classes are:

|| Queue Name || Priority Class || Cost \\
factor || Policy \\
SLA || Description || Specifications ||
| urgent | Urgent | 1 | MAY | Approved by LinkSCEEM-2 Scientific Coordinator \\
or, HPC Site Principal, on a case by case basis | as needed, for fulfilling site or project objectives. \\
Can be used after downtimes, for big jobs @ >50% |
| interactive | Interactive | 1 | MAY | For interactive jobs | prefer standing reservations; \\
maxsize @ 4 nodes; max walltime @ 2 hours |
| debug | Debug | 0 | SHOULD | Time/Resource limited for debug purposes | max walltime @ 30 minutes |
| batch | Standard | 1 | MUST | For approved LS2 projects | maxsize @ 50% of resources \\
max walltime @ 24hours |
| transfer | Standard | 1 | MAY | Data stage-in/stage-out jobs | used for jobs heavy in I/O meant for data transfers |
| gpu | Standard | 1 | MAY | For approved LS2 projects needing GPUs | Normal queue for GPU resources |
| gpu-low | Low Priority | 0 | MAY | For approved LS2 projects needing GPUs | No allocation subtraction |
| batch-low | Low Priority | 0 | MAY | For approved LS2 projects | No allocation subtraction |
The above list of queues, starting at urgent and ending at batch-low, denotes priorities from the highest to lowest, in that order.
