A method and apparatus for cross-computing power cluster communication, an electronic device, and a computer readable storage medium, are provided. An implementation of the method includes: in response to a communication initiator and a communication receiver respectively belonging to different computing power clusters, increasing a RDMA connection count on the basis of an initial connection count until a detected actual bandwidth value no longer increases, to obtain a target connection count; increasing, with the RDMA connection count being maintained at the target connection count, a Buffer size on the basis of an initial size until a detected actual bandwidth value no longer increases, to obtain a target size; determining cross-cluster transmission parameters, based on the target connection count and the target size; and communicating, cross-cluster transmission parameters, with the communication receiver belonging to a different computing power cluster.
