Re: [Condor-users] Jobs License Management

[Stuart Anderson <anderson@xxxxxxxxxxxxxxxx>]

In the context of the new Concurrency Limit will it be possible for a  
running job to drop a resource constraint when it is done with it, or  
is it implicitly assumed that all jobs require their specified  
resources for their entire lifetime?

The motivation for this is managing I/O resources where a typical work  
flow is to launch a large number of jobs that each read in a large  
amount data from a shared filesystem (or set of filesystems), and then  
crunch on the data for a long time before outputing a relatively small  
amount of results. It would be interesting to be able to hand out  
tokens for filer access but then be able to return them after the I/O  
intensive phase of each individual job is done.

Thanks.
