This page tries to describe the job scheduling policy on Sigma, i.e how the system decides which jobs should be started and when.
The scheduling policy for Sigma is identical to the one on Tetralith (read about it here) with the following exceptions:
This has been decided in dialogue with the LiU Sigma projects, to ensure that queue times does not become too long. Since Sigma only has 108 compute nodes, allowing 7 days jobs would mean that only a small number of nodes become available for new jobs each day, and queue times could sometimes be very high even for high-priority projects.↩
This has been decided in dialogue with the LiU Sigma projects. The idea is to have a relatively large number of devel nodes that can be allocated for a full workday, to better allow for interactive access to resources for users who need it. The number of devel nodes may change over time depending on usage.↩
