SUMMARY:FatPaths: Routing in Supercomputers and Data Centers when Shortest
  Paths Fall Short
DESCRIPTION:Paper\n\nFatPaths: Routing in Supercomputers and Data Centers 
 when Shortest Paths Fall Short\n\nBesta, Schneider, Konieczny, Cynk, Henri
 ksson...\n\nWe introduce FatPaths; a simple, generic and robust routing ar
 chitecture that enables state-of-the-art low-diameter topologies such as S
 lim Fly to achieve unprecedented performance. FatPaths targets Ethernet st
 acks in both HPC supercomputers as well as cloud data centers and clusters
 . FatPaths exposes and exploits the rich ("fat") diversity of both minimal
  and non-minimal paths for high-performance multi-pathing. Moreover, FatPa
 ths uses a redesigned "purified" transport layer that removes virtually al
 l TCP performance issues (e.g., the slow start), and incorporates flowlet 
 switching, a technique used to prevent packet reordering in TCP networks, 
 to enable very simple and effective load balancing. Our design enables rec
 ent low-diameter topologies to outperform powerful Clos designs, achieving
  15% higher net throughput at 2x lower latency for comparable cost. FatPat
 hs will significantly accelerate Ethernet clusters that form more than 50%
  of the Top500 list and it may become a standard routing scheme for modern
  topologies.\n\nTag: Algorithms, Networks, Reconfigurable Computing, Routi
