Configuration

Some configuration is possible:

• PRISMS_JOBS_DIR: (optional, default=``$HOME/.prisms_jobs``)

  The jobs database is stored at $PBS_JOB_DIR/jobs.db.

• PRISMS_JOBS_DIR/config.json:

  Automatically generated JSON configuration file storing settings:

  • "dbpath": (str)

    The location of the SQLite jobs database.

  • "software": (str)

    The job submission software interface to use. "torque" or "slurm" is automatically detected if present.

    “torque”	TORQUE
    “slurm”	Slurm
    “default” (or null)	Empty stub, does nothing
    other	The name of an existing findable python module implementing an interface

  • "write_submit_script": (bool, optional, default=false)

    If true, submit jobs by first writing a submit script file and then submitting it. Otherwise, by default, the job is submitted via the command line.

  • "update_method": (str, optional, default=”default”)

    Controls which jobs are updated when JobDB.update() is called.

    “default” (or null)	Select jobs with jobstatus != ‘C’
    “check_hostname”	Select jobs with jobstatus != ‘C’ and matching hostname. This is useful on compute clusters where multiple machines with different queues share the same PRISMS_JOBS_DIR.

  • "taskmaster_job_kwargs": (JSON object, optional)

    Holds options for the taskmaster job. Defaults are:

    ‘name’	“taskmaster”
    ‘account’	“prismsprojectdebug_fluxoe”
    ‘nodes’	“1”
    ‘ppn’	“1”
    ‘walltime’	“1:00:00”
    ‘pmem’	“3800mb”
    ‘qos’	“flux”
    ‘queue’	“fluxoe”
    ‘message’	null
    ‘email’	null
    ‘priority’	“-1000”
    ‘command’	“rm taskmaster.o*; rm taskmaster.e*\n”
    ‘auto’	false

    Additionally, the 'exetime' is set based on the --delay commandline argument and the commandline invocation used to launch taskmaster is appended to 'command'.
