Abstract :
The paper investigates an impact of direct and combining collective communications models that may be critical for performance of parallel applications. Analysis provided for any given start-up time and message transfer time reveals the fastest collective communication mode in relation to the number of processing elements in 2D meshes and fat tree networks on a chip.
