Contention-Free 2D-Mesh Cluster Allocation in Hypercubes

Tkaditionally, each job in a hypercube multiprocessor is allocated with a subcube so that communication interference among jobs may be avoided. Although the hypercube is a powerful processor topology, the 2D mesh is a more popular application topology. This paper predents a 2Dmesh cluster allocation strategy for hypercubes. The proposed auxiliary free list procwor allocation strategy can efficiently allocate 2D-mesh clusters without size constraints, can reduce average job turnaround time compared with that based on subcubc allocation strategies, and can guarantee no communication interference among allocated clusters when the underlying hypercube implements deadlockfree Ecube routing. The proposed auxiIiary free list strategy can be easily implemented on hypercube multicomputers to increage processor utilization.
