@@ -97,6 +97,9 @@ There are four types of REMAP:
 * **Parallel Reduction**, for scheduling a sequence of operations
   in a Deterministic fashion, in a way that may be parallelised,
   to reduce a Vector down to a single value.
+* **Parallel Prefix Sum**, implemented as a work-efficient Schedule,

+  Deterministic.
 
 Best implemented on top of a Multi-Issue Out-of-Order Micro-architecture,
 REMAP Schedules are 100% Deterministic **including Indexing** and are
