     19* '''Checkpointed computations can run ''longer than cluster walltime limits''.''' See '''--qos=long''' in [wiki:cypress/about#SLURMresourcemanager SLURM (resource manager)].
     20
    1921* '''Checkpointed jobs can get started sooner''' out of the job queue pending state with a reduced requested run time. (See "backfill scheduling" in [https://slurm.schedmd.com/sched_config.html|SLURM Scheduling Configuration Guide].
    2022* '''More checkpointed jobs can run simultaneously''' due to strict limits enforced by Cypress, LONI, and most other production clusters.
    21  * See see '''--qos=normal''' in [wiki:cypress/about#SLURMresourcemanager SLURM (resource manager)].
     23 * See '''--qos=normal''' in [wiki:cypress/about#SLURMresourcemanager SLURM (resource manager)].
    2224 * See also the command
    2325   * '''sacctmgr show qos format=Name,!MaxWall,!MaxNodesPerUser | grep -E "normal|long"'''
    2426* '''Checkpointing mitigates the loss of resources and data due to either hardware failures or infinite looping jobs ''' - especially for otherwise long running parallel MPI jobs.
    2527* '''Checkpointed jobs can handle frequent job pre-emption''' - especially for certain cloud-based job queues with high availability.
    26 * '''Easier maintenance for HPC cluster managers''' - shorter maintenance periods waiting for nodes to become idle for servicing and reduced risk from less need for postponement of updates for security, hardware, and software.
     28* '''Easier maintenance for HPC cluster managers''' - shorter maintenance periods waiting for nodes to become idle for servicing and reduced risk with quicker updates for security, hardware, and software.
