+# This matrix is intended to permit Jenkins:
+# - nigtly testing of the GPU direct communations experimental features in the 2020 release
+# - on-demand testing of the GPU direct communication code path
+# This is neceassary due to:

+# ii) limitations of the regresssion tests which are not able to rerun update with a
+#     different offload mode unless the default is observed to be GPU.
