FatPaths: Multipath Routing in Supercomputers and Data centers when Shortest Paths Fall Short

We illustrate how to effectively apply multipath routing for more performance in modern low-diameter networks in large-scale data centers and supercomputers using both minimal and non-minimal paths. See papers and reports below for more details!
