+      <p>
+	<a href="mpi_sync_clocks/doc/">MPI Sync Clocks</a> is an
+        implementation of synchronized clocks using MPI. It offers:
+        <ul>
+          <li><i>interpolated clocks</i> to get a consistent clock accross nodes
+            through interpolation, i.e. computed at the end of the
+            execution. This is the most precise method.</li>
+          <li> extrapolated clocks to compute consistent clocks accross nodes in
+            realtime. This method is less precise than interpolation.</li>
+          <li><i>synchronized barrier</i>: a barrier that guarantees to exit on all
+            nodes at the same time, contrary to <tt>MPI_Barrier</tt>. This is
+            especially useful to benchmark collective operations.
+        </ul>
