 It is possible to control precisely the placement of a specific lock on a specific physical memory bank by defining a specific vseg in the application mapping.

+The sqt_lock can be used in multi-clusters architectures, and is implemented as a - physically distributed - Synchronisation-Quad-Tree (SQT). The SQT topology is completely defined by the (x_size / y_size) parameters, with the following constraints:
+ * The involved clusters form a mesh(x_size * y_size).
+ * The lower left involved cluster is cluster(0,0).
+ * All involved clusters must contain a heap_x_y vseg declared in the mapping.
+ * The number of involved tasks in a given cluster is the same for all involved clusters.
