+Currently there are only two operations implemented.<h2><a class="anchor" name="MOC_Bcast">
+MOC_Bcast</a></h2>
+The root node sends normal messages using the reserved tag MOC_BCAST_TAG, which is received by all other nodes.<h2><a class="anchor" name="MOC_Barrier">
+MOC_Barrier</a></h2>
+All but the process with the highest rank send a special-message (special-flag set) to the latter process. This process then sends another special-message back to the others. After that the function returns on all calling processes.
