[slurm-users] Slurm Perl API use and examples

Do you use the Perl API to submit jobs/request allocations, or only to query the state of jobs, etc.? If you submit jobs, how do you populate the hash that is passed as a job_desc_msg_t structure? Thanks,

    In fact, we ARE using the perl API, but there are some flaws.
    E.g. the array_task_str of the jobinfo structure. Slurm abbreviates long 
    list of array indices, like scontrol does:
    yes, you can really find there three dots. In my opinion, this is ok for 
    a general tool like scontrol to abbreviate the output, but it does not 
    make any sense within a API.
    Does anyone know, if the C-API also abbreviates things like that?

In Perl, it's just a hash, am I supposed to populate the keys of the hash by reading the matching C structure in slurm.h? Or do I only need to populate the keys that I care to provide a value for, and Slurm assigns defaults to the other keys/fields? Thanks,
