Re: [HTCondor-users] Move jobs of users from one to another worker node

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi Gagan,

moving whole job states between machines is not possible with Condor (I 
am unsure, if another LRMS can achieve something like that especially 
since there is no freezer with cgroups v2 anymore. Maybe if you have MPI 
applications, but these would have to sort their memory handling 
themselves, I guess)

of course, you can always put a job onto hold, edit its rerquirements 
and resubmit it targeting another EP.

Cheers,
  Thomas
