Abstract: A multi-path routing method oriented to supercomputing user experience quality includes: decoupling, according to a preset rule, a service with a path to be planned into at least one service block; acquiring, according to a network requirement feature of each service block, all paths between network nodes of the path to be planned, and a network feature of each of all the paths, a multi-path set between the network nodes for the service; and inputting the network feature of each path in the multi-path set and the network requirement features of all the service blocks into a preset matching degree evaluation function to acquire a network path between the network nodes for the service. According to the multi-path routing method, the overall service of the network is described in blocks, so that a strong dependency relationship between supercomputing service task scheduling and data exchange is decoupled.

Abstract: A personalized comment recommendation method based on a link prediction model of a graph bidirectional aggregation network. In a user-comment bipartite graph, comment features are aggregated into a user feature. A social network is used to fuse a neighbor feature of a user to obtain an embedding representation of the user. The embedding representation of the user is aggregated into a comment after an original feature of the user is removed, and the embedding representation of the user is adjusted based on a difference before and after comment aggregation. On this basis, a forwarding network is used to calculate a score of an edge based on an inner product of user node features at both ends of the edge, and finally make a recommendation based on the score. Furthermore, a recommendation system converts a comment recommendation task into a link prediction task between users in a small range.

Abstract: A network edge storage apparatus having a security feature is disclosed. A file selected from a network attached storage (NAS) device is encrypted by means of encryption software embedded in a development board, causing a user without an encryption key to fail to acquire the encrypted file from the NAS device; and/or even if a user without an encryption key can acquire the encrypted file from the NAS device by means of a local area network (LAN), the user still has no means of acquiring the specific content of the encrypted file, such that the security is improved. All files in the NAS device may be selected and encrypted to ensure that a user without an encryption key has no means of acquiring any file and the specific content thereof from the NAS device, which further improves the security.

Abstract: The data caching method and a storage medium includes acquiring, by receiving the request of caching service data sent by the UE, the network status data between an SBS corresponding to UE and the UE, the network status data between an MBS corresponding to the SBS and the UE, and the network status data between the UE and a data source of the service data. According to the types of the three pieces of network status data and the service data, three corresponding QoE values are acquired, and whether the cache is configured for the UE is determined according to the three QoE values. The quantification of the three QoE values is realized, and whether the cache is configured for the UE is determined according to the quantized QoE values, thereby achieving the effect of improving the quality of user experience.
