 Description
 -----------
 
+GatherWorkspaces is only available for MPI builds.
 It stitches together the input workspaces provided by each of the processes into a single workspace in the root process.
 The spectra in the output workspace will be ordered by the rank of the input processes.
 It is up to the caller to ensure this results in the required ordering.
