Re: [Condor-users] slight bug in dynamic slots

[Matt Hope <matt.hope@xxxxxxxxxxxxxxx>]

That does suggest that the system should default CLAIM_WORKLIFE to zero for dynamic slots... can anyone think of a reason *not* to always do that?

Hi Erik,

You can change tihs behaviour by setting variable CLAIM_WORKLIFE.
http://www.cs.wisc.edu/condor/manual/v7.4/3_3Configuration.html#16308

This variable specifies the number of seconds after which a claim will stop
accepting additional jobs.

Regards,
Lukas
