Abstract: A method is applied to a computing cluster. The computing cluster includes a plurality of inference servers and a memory pool. Each inference server includes at least one inference card and a local memory. The method includes: a first inference card of a first inference server in the computing cluster receives an inference task. If a parameter for executing the inference task is not hit in the first inference card, the first inference card obtains the parameter from a local memory of the first server. If the parameter is not hit in the local memory of the first server, the first inference card obtains the parameter from the memory pool. The first inference card can execute the inference task based on all obtained parameters.
