Re: [HTCondor-users] Fwd: Manually Setting ClusterID

[Francisco Leite de Castro <frankie.lc@xxxxxxxxx>]

Ben,

Many thanks for the reply!

I had also asked the same question to StackOverflow and, in the spirit of the site looked you up, did not found you and as such answered myself giving credit where credit is due.

http://stackoverflow.com/questions/26851189/manually-define-clusterid-of-htcondor/26872300#26872300

If you disagree with it being posted or want to remove your name / company please let me know.

Thank you very much,

Francisco

Francisco,

Good news! SCHEDD_CLUSTER_INITIAL_VALUE is the schedd setting you
want. From the manual:

An integer that specifies the initial cluster number value to use
within a job id when a job is first submitted. If the job cluster
number reaches the value set by SCHEDD_CLUSTER_MAXIMUM_VALUE and
wraps, it will be re-set to the value given by this variable. The
default value is 1.

It might be a good idea, if it's possible, to modify your external
services to use GlobalJobId to identify jobs instead of just the
straight job id. I have a patch submitted (poke, poke, Todd) to add
the following to the ClassAd reference:

A globally-unique job identifier. Contains the queue name, JobId, and
schedd start time (in seconds since Jan 1, 1970) joined by #. For
example, submit.example.com#152.3#1358363336

The inclusion of the schedd start time helps prevent issues like
you're encountering (plus eventually the odometer will reset on your
cluster ID anyway).


Thanks,
BC
