Therefore, the normal architecture of one switch port per end-host is very wasteful because of the need for high port density switches to support numerous end users.
Hence, high-port-count optical circuit switches are urgently needed.
The ITRS projections for signal-pin count and per-pin bandwidth are nearly flat over the next decade, so increased radix in electronic switches will come at the cost of less per-port bandwidth.

Fast optical switches based on a silicon photonics platform can enable the high port speed and high interconnection density needed while still maintaining a small footprint and low power consumption.
Thus, it is critical to devise ways to build large crossconnects from a small number of constituent switches, each with reduced port count.
This article proposes a novel microarchitecture that allows flat crossbar switches to scale to 128 ports, supporting 32 Gbits per second per port (Gbps/port) while occupying 4.9 mm^2 and consuming 4.2 W, or supporting 64 Gbps/port at 7.5 mm^2 and 7.5 W, in 45-nm CMOS.
We find that there is a tradeoff among concentration of residue (for high throughput), strictness of fairness (to prevent starvation), and implementational simplicity (for the design of high-speed switches).

How fluid domains of a CFD simulation is represented.?
5 answers
Fluid domains in a Computational Fluid Dynamics (CFD) simulation can be represented in various ways. One method involves using the incompressible Navier-Stokes equations for the fluid and describing the structure with Ordinary Differential Equations (ODE) on a fixed mesh. Another approach excludes the monolith from the computational domain, creating two mapped domains upstream and downstream of the monolith, allowing for detailed flow profile results without the complexity of a full 3D calculation. Additionally, a novel method utilizes a graph neural network architecture to simulate fluid flow fields, treating the computational domain as a structural graph and training the simulator based on flow results around a cylinder. Furthermore, a technique combines Particle Finite Element Method (PFEM) for the fluid domain and Finite Element Method (FEM) for the solid domain, enabling efficient simulations of Fluid-Structure Interaction (FSI) problems with large displacements.
