WebJan 1, 2015 · In the data transfer phase, the non-root processes will use the RDMA-Write operation for the All-to-one collective pattern and the RDMA-Read operation for the One-to-all collective pattern. We choose different RDMA primitives for these collectives to reduce the load on the IB HCA at the root of the collective. We use the RDMA-Write primitive ... WebAu début, il n'y avait pas de NVLink à l'intérieur de la machine unique, pas de RDMA sur le réseau et la bande passante était relativement faible. Il n'y avait pas beaucoup de différence de bande passante entre la distribution sur une seule machine et la distribution sur plusieurs machines, il suffisait donc de construire un grand anneau. combination infrared and steam sauna
