 The text is thus organised into three parts:

+\teaMPI's design is conceptionally very simple:
+
+\begin{itemize}
+  \item The user code links against the \teaMPI\ library which in turn hooks
+  into the PMPI interface. As a result, \teaMPI\ can hijack MPI calls, map them
+  onto subcommunicators (subsets of ranks) or trigger special functions besides
+  the MPI core functionality.
+  \item Furthermore, \teaMPI\ provides an API such that programmers can inform
+  it about tasks, e.g., or query load balancing information.
+  \item If \teaMPI\ is built with SmartNIC support, each library running on the
+  host is paired up with a SmartTea instance running on the BlueField. The
+  library now can interact with the \teaMPI\ instance running on the SmartNIC
+  and the two of them can orchestrate data transfer completely independent of
+  the user application.
