A new proposal to deal with congestion in InfiniBand-based fat-trees
Cost-efficient network-interconnect designs are a critical task for the HPC Systems. Congestion degrades the network performance: congestion management (CM) is required. InfiniBand(IB)-based interconnection networks have a strong presence in the HPC Systems. Flow2SL is a new CM technique for IB Fat-trees, based on mapping traffic-flows to SLs. Flow2SL achieves up to a 68% of improvement compared to the ideal performance gain.
