+# With an update to CUDA driver R575 or newer UCX fails to create a registration cache
+# This cache is essential to prevent having to pin memory for every individual data
+# transfer. Pinning memory for every individual transfer introduces a high overhead on
+# every transfer, crippling performance
+# A patch was introduced to solve the issue, this rebuild reinstalls UCX with that patch.
+# More information, see https://gitlab.com/eessi/support/-/issues/209
