Abstract: A method for implementing collective communication, a computer device, and a communication system are provided, to resolve problems of high communication latency and resource consumption in the conventional technology. The method includes: identifying a work request having no communication dependency, and when forwarding work requests, directly forwarding the work request identified as having no communication dependency, and forwarding, after queue management, a work request that is not identified as having no communication dependency. According to the application, communication latency caused when the work request having no communication dependency is managed by using a queue can be avoided, and resource consumption caused by performing related management can be reduced, to improve overall communication performance of collective communication.

Abstract: In a data processing method, a first server receives control stream information from a terminal, parses the control stream information, starts a game based on a game identifier (ID) in the control stream information, and intercepts instruction stream information. An Android stimulator is deployed on the first server. The first server sends the instruction stream information to a second server. The second server is in a graphics processing unit (GPU) resource pool. The second server selects a target GPU from the GPU resource pool to process the instruction stream information, completes image rendering and encoding, and generates video stream information. The second server sends the video stream information to the terminal. The terminal displays the video stream information to a user.

Abstract: The present disclosure relates to methods and apparatuses for processing a control packet in a collective communication system, where the collective communication system includes a switch network and multiple computing nodes, and the switch network includes a first switch. In one example method, the first switch forwards a query packet transmitted by a source node to a destination node, where the query packet is generated by the source node based on a context of the collective communication system. Then, the first switch forwards a notification packet transmitted by the destination node to the source node, where the notification packet carries an in-network computing capability of the switch network.

Abstract: The present disclosure provides a technique for quantitatively detecting alkaline phosphatase (ALP) activities in seawater and other aquatic environments, based on surface-enhanced Raman spectroscopy by taking 5-bromo-4-chloro-3-indolyl phosphate (BCIP) as a substrate and dimethyl sulfoxide (DMSO) as an internal standard. Results show that ALP activity has a good linear correlation with the intensity ratio of a characteristic Raman peak to that of the internal standard peak (600 cm?1/677 cm?1) (R2=0.977). The technique was successfully applied to detect ALP activity of a seawater sample. By extension this technique can also be used in detecting the activity of other microbial extracellular enzymes (e.g., aminopeptidase) in seawater and thus, lays a solid scientific foundation for in-situ detection of the activities of other extracellular enzymes in seawater and other aquatic environments.
