We propose cooperative communication as a means to enable efficient and scalable barrier synchronization on mesh-based manycore architectures. Our approach is different from but orthogonal to conventional algorithm-based optimizations. It relies on collaborating routers to provide efficient gather and multicast communication. In conjunction with a master-slave algorithm, it exploits the mesh regularity to achieve efficiency. The gather and multicast functions have been implemented in our router… CONTINUE READING
