6 crunch-job: Execute job steps, save snapshots as requested, collate output.
10 Obtain job details from Arvados, run tasks on compute nodes (typically
11 invoked by scheduler on controller):
13 crunch-job --job x-y-z
15 Obtain job details from command line, run tasks on local machine
16 (typically invoked by application or developer on VM):
18 crunch-job --job '{"script_version":"/path/to/tree","script":"scriptname",...}'
26 If the job is already locked, steal the lock and run it anyway.
30 Path to .git directory where the specified commit is found.
34 Arvados API authorization token to use during the course of the job.
38 Do not clear per-job/task temporary directories during initial job
39 setup. This can speed up development and debugging when running jobs
44 =head1 RUNNING JOBS LOCALLY
46 crunch-job's log messages appear on stderr along with the job tasks'
47 stderr streams. The log is saved in Keep at each checkpoint and when
50 If the job succeeds, the job's output locator is printed on stdout.
52 While the job is running, the following signals are accepted:
56 =item control-C, SIGINT, SIGQUIT
58 Save a checkpoint, terminate any job tasks that are running, and stop.
62 Save a checkpoint and continue.
66 Refresh node allocation (i.e., check whether any nodes have been added
67 or unallocated) and attributes of the Job record that should affect
68 behavior (e.g., cancel job if cancelled_at becomes non-nil).
