+It optimizes Google's fleet by recommending clusters where workloads should be
+scheduled. Highligths:
+
+\begin{itemize}
+
+\item Fix a bug manifesting across multiple systems which lead to workloads being
+placed in overutilized clusers.
+
+\item Consider power utilization signal in cluster recommendations.
+
+\item Change cluster recommendations to reduce inter-cluster network traffic by
+up to 90\%.
