condor_shadow (cont’d)
The shadow doesn’t put much load on your submit machine:
- Almost always blocked waiting for requests from the job or doing I/O
- Relatively small memory footprint
Still, you can limit the impact of the shadows on a given submit machine:
- They can be started by Condor with a “nice-level” that you configure (renice)
- Can put a limit on the total number of shadows running on a machine
