Currently, our testbed includes the following nodes.
Note that some nodes can be submitted via vanilla universe only,
parallel universe only,
or both.

## Constraining jobs to run on a subset of available nodes

This information can be used to [write ClassAd constraints](https://htcondor.readthedocs.io/en/latest/man-pages/condor_submit.html#requirements).
For example,

```ini
requirements = (machine == "wn1905340.in.tier2.hep.manchester.ac.uk`") || (machine == "wn5914090.in.tier2.hep.manchester.ac.uk`") || (machine == "wn5916090.in.tier2.hep.manchester.ac.uk`") || (machine == "wn5916340.in.tier2.hep.manchester.ac.uk`") || (machine == "wn5914340.in.tier2.hep.manchester.ac.uk`") || (machine == "wn5917090.in.tier2.hep.manchester.ac.uk`")
