 The ''giet_sbt_barrier_t'' can be used in multi-clusters architectures, and is implemented as a physically distributed Sliced-Binary-Tree (SBT).
-To use this distributed barrier, some placement constraints must be respected:
+The SBT topology is completely defined by the number of tasks, with the following constraints:
  * The number of tasks must be a power of 2.
- * There is one task per processor in a given cluster.
- * The involved clusters form a mesh[X][Y] where (X = Y) or (x = 2*Y)
- * The lower left involved cluster is cluster(0,0)  
+ * There is one task per processor.
+ * The involved clusters form a mesh[X][Y] where (X = Y) or (X = 2*Y).
+ * The lower left involved cluster is cluster(0,0).
+ * All involved clusters must contain a heap[x][y] vseg declared in the mapping.
