In this paper, the authors propose a processor allocation mechanism for run-time assignment of a set of communicating tasks of input applications onto the processing nodes of a Chip Multi-Processor (CMP), when the arrival order and execution lifetime of the input applications are not known a priori. This mechanism targets the on-chip communication and aims to reduce the power and latency of the NoC employed as the communication infrastructure. In this paper, they benefit from the advantages of non-contiguous processor allocation mechanisms, by allowing the tasks of the input application mapped onto disjoint regions (sub-meshes) and then virtually connecting them by bypassing the router pipeline stages of the inter-region routers.
