The invention discloses a communication performance prediction method and device for communication competition between parallel application cores, and relates to the technical field of communication performance prediction. The heterogeneous multi-core processor model extracts and runs a first concurrent task of the parallel application communication data in stages, obtains the processing time of the first concurrent task, records the processing time in a preset polling time interval table, acts on the remaining concurrent tasks as an initial polling time interval, and runs the remaining concurrent tasks on the heterogeneous multi-core processor model at the same time; and increasing or decreasing the initial rotation training time interval according to the subsequent residual concurrent task processing time and recording the initial rotation training time interval. According to the method, the communication framework suitable for communication of the heterogeneous multi-core processor is selected according to
