Tools

The following tools are useful for interacting or otherwise using SLURM.

• JobMaker is a small interface that a center can deploy, customized to their slurm.conf. Since the slurm.conf is readable by all nodes, a user can generate the data for the tool equivalently.
• JobStats makes it easy for users to see status of jobs, and what resources were actually utilized from those requested.
• doppler is a complementary web application to jobstats that shows users, and account job efficiency/resource wastage.
• smanage is a tool developed out of Harvard to help with management of job arrays.
