NIC-Based Reduction in Myrinet Clusters : Is It Beneficial ?

  title={NIC-Based Reduction in Myrinet Clusters : Is It Beneficial ?},
  author={Darius Buntinas and Dhabaleswar K. Panda},
Reduction-to-one and reduction-to-all operations are common operations in parallel and distributed systems. These operations are collective operations which can involve many processes. It is therefore important to make these operations fast and efficient. Some modern network interface controllers (NICs) for system area networks (SANs) have programmable processors which can be used to offload protocol processing from the host processor. In this paper we investigate the use of the NIC processor… CONTINUE READING
