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

[John M Knoeller <johnkn@xxxxxxxxxxx>]

If it problem is that the submit node is the only machine with sufficient memory to run this job, one possible solution is to run a STARTD on the submit node that only accepts jobs with a certain attribute.  

While you can't count on changing the job universe of a job using condor_qedit.  you can certainly count on being able to add or modify some other attribute. 

for instance. have the STARTD running on the submit node that has 

START = TARGET.SpecialHighMemoryJob

And use condor_qedit to set

SpecialHighMemoryJob = true

In the situations where you were thinking of using condor_qedit to change JobUniverse to local.

Miron,

it's already too late: when you find that a submitted job won't match any
available machine  this after ... before timespan is over.
Thanks for the suggestion even if doesn't help now.
Changing the JobUniverse was only one possible (or rather impossible) option
to cope with oversized jobs generated by DagMan - fortunately there are more.
We're going for more memory in selected nodes.
