The number of endnodes in high-performance computing and datacenter systems is constantly increasing. Hence, it is crucial to minimize the impact of network congestion to guarantee a suitable network performance. InfiniBand is a prominent interconnect technology that allows implementing efficient topologies and routing algorithms, as well as queuing schemes that reduce the head-of-line (HoL) blocking effect derived from congestion situations. Here, we explain and evaluate thoroughly a queuing scheme called Path2SL that optimizes the use of the InfiniBand Virtual Lanes to reduce the HoL blocking in fat-tree network topologies.

Path2SL：利用 InfiniBand 资源减少胖树中的队头阻塞

高性能计算和数据中心系统中的终端节点数量不断增加。因此，最大限度地减少网络拥塞的影响以保证合适的网络性能至关重要。InfiniBand 是一种突出的互连技术，它允许实施高效的拓扑和路由算法，以及减少由于拥塞情况导致的队头 (HoL) 阻塞效应的排队方案。在这里，我们彻底解释和评估称为 Path2SL 的排队方案，该方案优化了 InfiniBand 虚拟通道的使用，以减少胖树网络拓扑中的 HoL 阻塞。
