Abstract :
We consider a balanced combined application of the known LPGS- and LSGP-partitioning which we call co-partitioning. This approach allows a structural adjustment of the array design as well as a balancing of the size of the local memory and the IO-demand between the processing elements of the co-partitioned array. We determine the size of the LSGP-partitions such that there exists a sequential scheduling within the LSGP-partitions which is free of wait states. We give the proof for the existence of such a scheduling, and we give explicit formulas for the lower and upper bounds of the loops of a for-loop program which represents one of the possible sequential schedulings
