    $WORK and $SCRATCH by logging in to the machine.
    A new configuration for KNL nodes is being worked on, but not yet included
    in the release (but compilation works and tests mostly pass).
+#  ML_ADMConstraints: There seems to be a problem regarding calculating the
+   constraints from the BSSN quantities. The exact problem is not known yet,
+   but indications point towards a compiler problem (Intel in all cases).
+   One consistent symptom is failing of the Dissipation and RotatingSymmetry
+   testsuites (as they include output of the constraints using
+   ML_ADMConstraints). Investigations on this matter will continue,
+   new findings, together with workarounds/solutions will be announced on
+   the users mailing list, and will be back-ported into the release branch.
+   Updates can be found in ticket #1995:
+     https://trac.einsteintoolkit.org/ticket/1995
