1 ### Structure of queue directories ###
3 <queue>/hosts/<hostname>/ Jobs queued for the given host
4 (they are executed in the lexicographic order of <job-id>s)
5 /<job-id>.job Symlink to <queue>/jobs/<job-id>.job
6 /<job-id>.stat (Optional) status of the job
7 /<job-id>.tmp Used temporarily by brun to store the script actually
8 sent to the host (can be inspected if something goes wrong)
9 /<job-id>.log (Optional) transcript of output produced by the job (including
10 previous failed attempts)
12 <queue>/jobs/<job-id>.job All jobs issued on this queue, including those which
13 are no longer queued for any machine
15 <queue>/history/<hostname>/ Successfully completed jobs (their .job, .stat and .log files)
16 are moved here if the keep_history config switch is set.
18 <queue>/log Log of actions on this queue. Lines look this way:
19 YYYY-MM-DD HH:MM:SS <host> <job-id> <status> [<msg>]
20 <status> and <msg> correspond to "Status" and "Message"
23 <queue>/status-fifo FIFO used for reporting status of subprocesses by `bprun'
27 Mail-like structure. First come the headers (<keyword>:<spaces><value>), keywords are
28 case-sensitive, no multi-line fields allowed, then an empty line and then the body
29 (i.e., commands to be executed on the remote host).
33 ID: <job-id> Identifier of the job, unique in the scope of a queue
34 Subject: <subject> Subject to be displayed to the user
38 Structure identical to job headers, but they do not contain a body.
42 Time: <timestamp> UNIX timestamp of the last status change
43 Status: <code> Machine-readable status of the job:
44 NOPING - host does not respond to ping
45 NOXFER - transfer of the job body to a temporary file
46 on the host has failed
47 RUN - job is running (present only in log files)
48 OK - job executed successfully (however, the job will
49 be removed from the queue immediately, so you are
50 not likely to see this code)
51 FAILED - job failed to execute (i.e., it returned
53 INTERR - internal error of BEX
54 Message: <msg> (Optional) human-readable message explaining the status
