The application provides an electric light truck urban cruise control method and system, which comprises the following steps: based on a federal learning architecture, the global parameters of an urban traffic cloud platform are updated cooperatively through a federal average algorithm; a working condition characteristic vector library covering global urban roads is constructed according to the global parameters, a migration learning algorithm is used to migrate the speed trajectory planning experience under the historical optimal working condition to the inside of the working condition characteristic vector library, and a source domain-target domain adaptation model is constructed in combination with the remaining battery capacity and power system state of the electric light truck; a speed trajectory initial framework corresponding to the electric light truck is output through the source domain-target domain adaptation model, and a corresponding optimization objective function is constructed according to the speed trajectory initial framework; preset constraint conditions are called out, and the optimal speed trajectory is calculated according to the constraint conditions and the optimization objective function, so that the corresponding urban cruise is completed according to the optimal speed trajectory. The application can effectively improve the cruise control efficiency of the electric light truck.

The application provides a method, device, storage medium and program product for improving RDMA dual-card switching efficiency, and belongs to the technical field of computer networks, and comprises the following steps: intercepting RDMA calling of an application program through a self-provided RDMA function library of an intermediate library; when the RDMA calling is intercepted, responding to the RDMA calling through the self-provided RDMA function library to perform RDMA communication, mapping resources required by the RDMA communication into resources of the intermediate library so that the application program directly accesses the resources of the intermediate library; standby resource preparation and pre-association; monitoring changes of RDMA network cards through the intermediate library, and when a failure of a main RDMA network card is monitored, the next step is entered; a failure signal and complete association of the standby resource; after the complete association is successfully completed, the resources of the intermediate library of the associated main RDMA network card are switched to the associated standby RDMA network card to continue the RDMA communication. The method further reduces the RDMA network card failure switching time.
