Development of multirail feature in MPC for BXI interconnect

Authors: Gilles Moreau (CEA), Hugo Taboada (CEA), Marc Pérache (CEA) 1  Introduction Context Nowadays, HPC applications scale to several hundred nodes, and MPI has become the de facto standard for internode communication. It abstracts Point-to-Point (P2P) communication to the application developer while taking advantage of the underlying network. With ever increasing demand for bandwidth-oriented communications, […]
