SRFabric: A Semi-Reconfigurable Rack Scale Topology

Table 1

Summary of main notations in this paper.

Symbol	Description
	SRFabric parameters: a Rack with SoCs, static, dynamic ports, and uplinks
	Costs of static link and dynamic port, respectively
	Node density and link density, respectively
	Probability that is less than hops
	Desired probability in terms of SPL for a topology
	Probability that the distance on SoCs exceeds

¹denotes the term “SPL” which means the shortest path length.
