Approaches presented herein enable cooling a data center with a cooling system having a relatively high coolant temperature. This cooling system is controlled by a building management system and includes piping through which coolant flows, an air cooling unit in thermal contact with the coolant, and a chiller to cool the coolant to a temperature between 18 and 22 degrees Celsius as instructed by the building management system.

Sparse scanout for image sensors
To support sparse scanout of an image sensor, an image data protocol such as the MIPI CSI protocol is extended with support for pixel coordinates in long packets. The receiver uses these to compute where in memory these pixels should be stored or where on a display they should be displayed. Truly sparse scanout is supported for any arbitrarily shaped image areas including for example elliptical readout for fisheye lenses. These techniques save MIPI and serializer/deserializer bandwidth in automotive and other applications, allowing for more cameras per vehicle or other host. Such techniques can be implemented in a way that is compatible with prior MIPI standardized approaches. |

In a networked data system, a discovery protocol enables clients to establish connections to one a plurality of database servers to utilize a distributed connection service. The service manages connections between application servers, i.e. clients, and databases. An initial request from the client is received by a load balancer. The load balancer responds to the client by identifying an assigned connection to one of the database servers based on load considerations. The client sends a secondary request directly to the assigned connection, bypassing the load balancer. The service establishes a persistent link on the assigned connection and assigns a time-to-live (TTL), during which the service connects data requests to the databases. Upon expiration of the TTL, the service completes a next data request received, then notifies the client that the connection is no longer valid, thereby requiring a new connection through the load balancer and rebalancing system traffic. |

Methods and apparatus for providing alternative content
Methods and apparatus that facilitate providing alternative content to customer devices in systems supporting DASH streaming are described. Various features relate to dynamically modifying and providing media presentation description (MPD) information to customer devices.

Magic state distillation with low space overhead and asymptotic input count
Disclosed herein are example embodiments of protocols to distill magic states for T-gates. Particular examples have low space overhead and use an asymptotically optimal number of input magic states to achieve a given target error. The space overhead, defined as the ratio between the physical qubits to the number of output magic states, is asymptotically constant, while both the number of input magic states used per output state and the T-gate depth of the circuit scale linearly in the logarithm of the target error. Unlike other distillation protocols, examples of the disclosed protocol achieve this performance without concatenation and the input magic states are injected at various steps in the circuit rather than all at the start of the circuit. Embodiments of the protocol can be modified to distill magic states for other gates at the third level of the Clifford hierarchy, with the same asymptotic performance. Embodiments of the protocol rely on the construction of weakly self-dual Calderbank-Shor-Steane codes (“CSS codes”) with many logical qubits and large distance, allowing one to implement control-Swaps on multiple qubits. This code is referred to herein as the “inner code”. The control-Swaps are then used to measure properties of the magic state and detect errors, using another code that is referred to as the “outer code”. Alternatively, one can use weakly-self dual CSS codes which implement controlled Hadamards for the inner code, reducing circuit depth. Several specific small examples of this protocol are disclosed herein. |
