Manage HTCondor jobs, job sets, dags, event logs, and resources
Synopsis
htcondor [ -h | --help ] [ -v | -q ]
Description
htcondor is a tool for managing HTCondor jobs, job sets, resources, event logs, and DAGs. It can replace condor_submit, condor_submit_dag, condor_q, condor_status, and condor_userlog, as well as all-new functionality and features. The user interface is more consistent than its predecessor tools.
The first argument of the htcondor command (ignoring any global options) is the noun representing an object in the HTCondor system to be operated on. The nouns include an individual job, jobset, eventlog, or a dag. Each noun is then followed by a noun-specific verb that describe the operation on that noun.
One of the following optional global option may appear before the noun:
Global Options
- htcondor -h, htcondor --help
Display the help message. Can also be specified after any verb to display the options available for each verb.
- htcondor -q …
Reduce verbosity of log messages.
- htcondor -v …
Increase verbosity of log messages.
A noun-specific verb appears after each noun; the verbs are sorted by noun in the list, which includes with their individual option flags.
Job Verbs
- htcondor job submit submit_file
Takes as an argument a submit file in the condor_submit job submit description language, and places a new job in an Access Point
htcondor job submit options
- htcondor job submit --resource resource_type submit_file
Resource type used to run this job. Currently supports
Slurm
andEC2
. Assumes the necessary setup is complete and security tokens available.- htcondor job submit --runtime runtime_in_seconds submit_file
Amount of time in seconds to allocate resources. Used in conjunction with the --resource flag.
- htcondor job submit --email address submit_file
Email address to receive notification messages. Used in conjunction with the --resource flag.
- htcondor job status
Takes as an argument a job id in the form of clusterid.procid, and returns a human readable presentation of the status of that job.
job status option
htcondor job status --skip-history job.id
Passed to the status verb to skip checking history if job not found in the active job queue.
- htcondor job resources
Takes as an argument a job id in the form of clusterid.procid, and returns a human readable presentation the machine resource used by this job.
Jobset Verbs
- htcondor jobset submit submit_file
Takes as an argument a submit file in the condor_submit job submit description language, and places a new job set in an Access Point
- htcondor jobset list
Succinctly lists all the jobsets in the queue which are owned by the current user.
htcondor jobset list options
- htcondor jobset list --allusers
Shows jobs from all users, not just those owned by the current user.
- htcondor jobset status submit_file
Takes as an argument a job set name, and shows detailed information about that job set.
htcondor jobset status options
- htcondor jobset status --nobatch
Shows jobs in a more detailed view, one line per job
- htcondor jobset status --owner ownername
Shows jobs from the specified job owner.
- htcondor jobset status --skiphistory
Shows detailed information only about active jobs in the queue, and ignore historical jobs which have left the queue. This runs much faster.
- htcondor jobset remove job_name
Takes as an argument a job_name in the queue, and removes it from the Access Point.
htcondor jobsets remove options
htcondor jobset remove --owner=owner_name Removes all jobs owned by the given owner.
Eventlog Verbs
- htcondor eventlog read logfile
Takes as an argument an event log to process. It may be the per-job or per-jobset eventlog, which was specified by the log = some_file in the submit description language. For a dag, it may also be the nodes.log file that all dags generate. Or, if the global event log is enabled by an administrator with the EVENT_LOG configuration knob, it may be the global event log, containing information about all jobs on the Access point.
Given this file, htcondor eventlog read returns information about all the contained jobs, and their status. It runs much faster than condor_history, because these logs are more concise than the history files. Unlike condor_history, it will also show information about jobs that have not yet left the queue.
- htcondor eventlog follow logfile
Takes as an argument an event log to process, as above, but instead of processing that file to completion, it does the equivalent of tail -f, and runs until interruption, emitting information about jobs as it appears in the file.
Eventlog Options
- --csv
By default, htcondor eventlog read emits a table of information in human readable format. With this option, the output is in a command separated value format, suitable for injestion by a spreadsheet or database.
- --json
Emits output in the json format. Only one of -csv or -json should be given.
- --group-by attributeName
With a job ad attribute name, instead of one line per job, emit one line summarizing all jobs that share the same value for the attribute name given. In the OSG, the GLIDEIN_SITE attribute is injected into all jobs, so one can quickly get a count of all jobs running, idle and exitted per site by using this option.
