I am getting the following warnings on BlueWaters when running the ET in a unigrid run and calling 

"CCTK_SyncGroup" from within a function that is scheduled as local:

^[[1mWARNING[L2,P0] (Carpet):^[[0m Synchronising group "ADMBASE::METRIC" in local mode

and so on for every group that is synced in these local functions.

I haven't seen this warning on bluesky (local RIT cluster) or my MacBook. 

Is it disallowed to sync in local mode? 

Best wishes,

Vassili
