Webschemes (DCQCN, DCTCP, TIMELY, and HPCC) vs. PFC when running on distributed training platforms. Our results indicate that previously proposed RoCE congestion control schemes have little impact on the end-to-end performance of training workloads, motivating the necessity of designing an optimized, yet low-overhead, congestion control scheme … Web17 mrt. 2024 · Network congestion is universally one of the main pain points of distributed systems. Precise telemetry data with per-packet granularity can be used to improve network observability and performance. This has already been demonstrated for RDMA networks by HPCC congestion control algorithm. WebThis is because HPCC resolves congestion in just one RTT, and converge to zero queue thereafter.

In this paper we consider productivity challenges for parallel programmers and explore ways that parallel language design might help improve end-user productivity. We offer a candidate list of desirable qualities for a parallel programming language, and describe how these qualities are addressed in the design of the Chapel language.

Web29 mrt. 2024 · HPCC+: High Precision Congestion Control In the early days of congestion control signaling, we originally came up with the rather crude “Source Quench” control message, an ICMP control message sent from an interior gateway to a packet source that directed the source to reduce its packet sending rate. Web在1988发表的论文《Congestion Avoidance and Control》中，Van Jacobson就提出丢包可以作为发生拥塞的信号，在当时的硬件性能下这个推论是成立的，后续的诸多拥塞控制算法也都是按照这个思路来实现（当然也有例外比如Vegas和Westwood），而如今网卡带宽已经从Mbps增长到了Gbps，丢包与拥塞这两者之间的关联 ...
