Dithering and dimming techniques for light emitting diode (LED) lighting systems
Various embodiments are described herein that relate to systems and methods for selectively providing current to power LEDs. The techniques introduced here can enable smooth dimming of the LEDs from maximum brightness down to “actual extinction” or “pseudo-extinction.” More specifically, the LEDs can be dimmed to extinction without any significant gaps in the levels of brightness (i.e., a noticeable drop rather than a smooth transition between brightness levels). Various pulse width modulation (PWM) and shunting techniques may be used to control the power provided to each color channel of an LED board. Conventionally, PWM often causes LEDs to produce an undesirable acoustic effect. However, by dithering the PWM signals between multiple predetermined positions once the frequency enters the audible range (e.g., below 25 kHz), the cumulative acoustic effect instead becomes white noise. |

Clustered dispersion of resource use in shared computing environments
Host machines and other devices performing synchronized operations can be dispersed across multiple racks in a data center to provide additional buffer capacity and to reduce the likelihood of congestion. The level of dispersion can depend on factors such as the level of oversubscription, as it can be undesirable in a highly connected network to push excessive host traffic into the aggregation fabric. As oversubscription levels increase, the amount of dispersion can be reduced and two or more host machines can be clustered on a given rack, or otherwise connected through the same edge switch. By clustering a portion of the machines, some of the host traffic can be redirected by the respective edge switch without entering the aggregation fabric. When provisioning hosts for a customer, application, or synchronized operation, for example, the levels of clustering and dispersion can be balanced to minimize the likelihood for congestion throughout the network. |
