Re: [HTCondor-users] Change JobUniverse from vanilla to local?

Hi John,

I understand - design decisions. So rewriting the DAG is the only way out of this misery...


Some other brain storm ideas -

1. How about running a condor_startd on your dagman/submit machine, and the START expression would be something like "only run jobs submitted by DAGMan that have been idle for over X amount of time" ?

2. Perhaps you could use the condor_jobrouter to transform a vanilla job into a local universe job?

I personally like option #1 better, since then the job remains vanilla universe, and the management of jobs is better.

Hope the above helps

The JobUniverse of a job cannot be changed after it is submitted, is that what you are asking?
There are decisions that the schedd makes once the job is submitted that it will not adjust correctly if you were to change the universe.

Good afternoon,

I've been asked whether it would be possible to change the JobUniverse
of a job (submitted by dagman) from "vanilla" to "local" to it could
be run on the submit node, not one of the compute nodes (which don't
fulfill the requirements as it turned out after starting the DAG).

I couldn't give a reliable answer. Can you help, please?
