The present disclosure relates to the technical field of oil and gas field exploitation, in particular to an early strength material suitable for a cement slurry system, a cement slurry composition, a cement slurry system, a preparation method therefor and the use thereof. The early strength material contains an aluminum salt, a sodium salt, crystal whiskers, an inorganic mineral and dispersing agent I, wherein the weight ratio of the aluminum salt, the sodium salt, the crystal whiskers, the inorganic mineral and dispersing agent I is (1-3):(1-3):(1-4):(1-8):1. The early strength material provided by the present invention has both high-temperature retarding performance and low-temperature early strength performance; meanwhile, while satisfying well cementing, the cement slurry system prepared from the cement slurry composition containing the early strength material can prolong thickening time of cement slurry under a high-temperature condition, can prevent ultra-retarding of top cement slurry under a low-temperature condition and has increased early strength.

Cement slurry system, preparation method therefor and use thereof

A well cementing method is described for improving cementing quality by controlling the hydration heat of cement slurry. By controlling the degree and/or rate of hydration heat release from cement slurry, the method improves the hydration heat release during formation of cement with curing of cement slurry, improves the binding quality between the cement and the interfaces, and in turn improves the cementing quality at the open hole section and/or the overlap section. The cementing method improves cementing quality of oil and gas wells and reduces the risk of annular pressure.

Disclosed are various examples of providing AI accelerator access as a service at the edge. In some embodiments an artificial intelligence (AI) accelerator device identifier is transmitted to register an AI accelerator with the AI broker service. An AI processing request for the AI accelerator is received from a networked computing device. A bus redirect of the AI accelerator to the networked device is enabled. An AI workload is performed controlled by the networked device through the bus redirect.

Edge AI accelerator service

Example methods are provided for a host to perform authentication offload in a virtualized computing environment that includes the host and a destination server. The method may comprise detecting, from a virtualized computing instance, a packet destined for the destination server. The method may also comprise: in response to determination that the detected packet is an authentication request, obtaining, from the virtualized computing instance, metadata associated with a client application for which authentication is requested; and sending the authentication request and the metadata to the destination server to cause the destination server to authenticate the client application based on the metadata.
