+# Non-baseline configurations.
+# These configurations have been tested on hera. For hera, the
+# memory use for the C3072 config is approx 60% of the full node,
+# C1152 is 12% of the full node and C768 is 8% of the full node.
+# The default is set as 12g on RDHPCS platforms and should be
+# sufficient for all but C3072. On hera C3072 requires approx 50min
+# of wall clock and using --exclusive. See C3072 settings in rt.sh
+#
+# Note that the 5deg ocean cases are currently only supported on
+# hera
