Abstract: This specification discloses example distributed table lock application methods and apparatuses, storage media, and electronic devices. In an example method, a master node receives a data processing request and determines a data table that to-be-processed data corresponding to the data processing request are located in. The master node generates a table lock for the data table; performs a lock operation on the data table and generates lock status information corresponding to the data table; writes the lock status information into a local log of the master node and synchronizes the log to a slave node such that the slave node stores the log. After the master node restarts, determines whether the master node stores the log; and in response to that the master node stores the log, restores the lock operation on the data table based on the lock status information recorded in the log.

Abstract: Embodiments are generally directed to compression in machine learning and deep learning processing. An embodiment of an apparatus for compression of untyped data includes a graphical processing unit (GPU) including a data compression pipeline, the data compression pipeline including a data port coupled with one or more shader cores, wherein the data port is to allow transfer of untyped data without format conversion, and a 3D compression/decompression unit to provide for compression of untyped data to be stored to a memory subsystem and decompression of untyped data from the memory subsystem.

Abstract: The present invention discloses a flat heat pipe, comprising a bottom plate, a top plate, and a support plate located between the bottom plate and the top plate; a micron-level radial strip is processed on the inner surface of the bottom plate; the inner surface of the top plate is processed with superhydrophilic and superhydrophobic radial structures arranged at intervals to transport the condensate to the direction of the surrounding pipe wall; a wick is arranged on the inner side of the support plate. The present invention has the function of pumpless directional transport of liquid and convergence of refluxed condensate; thereby improving the heat exchange performance of the entire flat heat pipe.

Abstract: A dimming assembly includes a first prism having a first surface and a second surface opposite to each other, and a second prism disposed on a side where the second surface of the first prism is located. The first surface includes first dimming portions, each of which includes two first side surfaces. Edges of the two first side surfaces away from the second surface intersect at a first intersection line. A surface of the second prism proximate to the second surface includes second dimming portions, each of which includes two second side surfaces. Edges of the two second side surfaces proximate to the second surface intersect at a second intersection line. A distance between orthographic projections of two adjacent first intersection lines on the second surface is less than a distance between orthographic projections of two adjacent second intersection lines on the second surface.
