The invention provides a general multiprocessor parallel calculation method and system. The method comprises the steps that a calculation task is obtained, hardware information and software information of all calculation nodes of a calculation resource are obtained, and the processing capacity of each the calculation node is calculated according to the hardware information and software information; according to the internal parallelizability of the calculation task, the calculation task is decomposed into multiple sub calculation tasks; according to the processing capacity of each calculation node, the sub calculation tasks are matched with all the nodes; according to a basic communication protocol, the data format of the sub calculation tasks is converted to a protocol format, and according to the matching relation, the sub calculation tasks are distributed to all the calculation nodes; according to the basic communication protocol, calculation results, of the protocol format, fed back by the calculation nodes are obtained, the data format of the calculation results is converted to the format of the original calculation task from the protocol format, and then the calculation results are fed back. Multiprocessor parallel calculation under the heterogeneous environment is achieved.
