Shadow exit status

(Source: h/exit.h)

Value Name Description
4 JOB_EXCEPTION The job exited with an exception
44 DPRINTF_ERROR There is a fatal error with dprintf()
100 JOB_EXITED The job exited (not killed)
101 JOB_CKPTED The job was checkpointed
102 JOB_KILLED The job was killed
103 JOB_COREDUMPED The job was killed and a core file produced
105 JOB_NO_MEM Not enough memory to start the shadow
106 JOB_SHADOW_USAGE incorrect arguments to condor_shadow
107 JOB_NOT_CKPTED The job was kicked off without a checkpoint
107 JOB_SHOULD_REQUEUE (!) We define this to the same number, since we want the same behavior. However, "JOB_NOT_CKPTED" doesn't mean much if we're not a standard universe job. The effect of this exit code is that we want the job to be put back in the job queue and run again.
108 JOB_NOT_STARTED Can't connect to startd or request refused
109 JOB_BAD_STATUS Job status != RUNNING on startup
110 JOB_EXEC_FAILED Exec failed for some reason other than ENOMEM
111 JOB_NO_CKPT_FILE There is no checkpoint file (lost)
112 JOB_SHOULD_HOLD The job should be put on hold
113 JOB_SHOULD_REMOVE The job should be removed
114 JOB_MISSED_DEFERRAL_TIME The job missed its deferred execution time
115 JOB_EXITED_AND_CLAIM_CLOSING Same as JOB_EXITED, but also inform schedd that the claim will not accept any more jobs

Other exit status

Value Name Description
-1073740777 ACCESS_VIOLATION Windows, AKA as C0000005
44 DPRINTF_ERROR There is a fatal error with dprintf()

GRAM Job States

Value GLOBUS_GRAM_PROTOCOL_ JOB_STATE_... Description
1 PENDING The job is waiting for resources to become available to run.
2 ACTIVE The job has received resources and the application is executing.
4 FAILED The job terminated before completion because an error, user-triggered cancel, or system-triggered cancel.
8 DONE The job completed successfully
16 SUSPENDED The job has been suspended. Resources which were allocated for this job may have been released due to some scheduler-specific reason.
32 UNSUBMITTED The job has not been submitted to the scheduler yet, pending the reception of the GLOBUS_GRAM_PROTOCOL_JOB_SIGNAL_COMMIT_REQUEST signal from a client.
64 STAGE_IN The job manager is staging in files to run the job.
128 STAGE_OUT The job manager is staging out files generated by the job.
0xFFFFF ALL A mask of all job states.

GRAM Signals

globus_gram_protocol_job_signal_t GRAM Signals

Value GLOBUS_GRAM_PROTOCOL_ JOB_SIGNAL_... Description
1 CANCEL Cancel a job
2 SUSPEND Suspend a job
3 RESUME Resume a previously suspended job
4 PRIORITY Change the priority of a job
5 COMMIT_REQUEST Signal the job manager to commence with a job submission if the job request was accompanied by the (two_state=yes) RSL attribute.
6 COMMIT_EXTEND Signal the job manager to wait an additional number of seconds (specified by an integer value string as the signal's argument) before timing out a two-phase job commit.
7 STDIO_UPDATE Signal the job manager to change the way it is currently handling standard output and/or standard error. The argument for this signal is an RSL containing new stdout, stderr, stdout_position, stderr_position, or remote_io_url relations.
8 STDIO_SIZE Signal the job manager to verify that streamed I/O has been completely received. The argument to this signal contains the number of bytes of stdout and stderr received, seperated by a space. The reply to this signal will be a SUCCESS message if these matched the amount sent by the job manager. Otherwise, an error reply indicating GLOBUS_GRAM_PROTOCOL_ERROR_STDIO_SIZE is returned. If standard output and standard error are merged, only one number should be sent as an argument to this signal. An argument of -1 for either stream size indicates that the client is not interested in the size of that stream.
9 STOP_MANAGER Signal the job manager to stop managing the current job and terminate. The job continues to run as normal. The job manager will send a state change callback with the job status being FAILED and the error GLOBUS_GRAM_PROTOCOL_ERROR_JM_STOPPED.
10 COMMIT_END Signal the job manager to clean up after the completion of the job if the job RSL contained the (two-phase = yes) relation.
