Scheduler selection, honestly assessed
Deadline and Tractor dominate for a reason: they understand DCC applications, licence-aware limits and per-task dependencies out of the box. OpenCue suits facilities that want to own their scheduler and have the engineers to do it. Slurm is the right answer when the same cluster also runs simulation and machine learning work and you want one accounting model. We will tell you when your existing scheduler is fine and the problem is elsewhere.
