摘要： A large-scale network node simulation method based on Linux container is provided, which solves problems of low packet transmission efficiency and multi-thread creation in real-time simulation in a large-scale network scenario. The method includes: scheduling all container nodes in a scenario; managing, by a container node, a dynamic thread through an idle thread management queue, and setting a finite state machine and a function pointer for the dynamic thread; registering, by a source container node, an output queue with a next-hop container node, and informing the next-hop container node to allocate a dynamic thread for receiving and processing the output queue. Packet transmission is realized between the container nodes through data units created in a shared memory. The sending thread and the receiving thread dynamically adjust the number of dynamic threads by checking the state of the output queue.

摘要： The present disclosure provides a bidirectional attention-based image-text cross-modal retrieval method, applicable for cross-modal retrieval between natural image and electronic text. The present disclosure extracts initial image and text features by using a neural network, and builds a bidirectional attention module to reconstruct the initial image and text features extracted by the neural network, the reconstructed features containing richer semantic information. By using the bidirectional attention module, the present disclosure improves the conventional feature extraction process, obtaining higher-order features with richer image and text semantics, thereby realizing image-text cross-modal retrieval.
