A computing cooperation method supporting multiple computing tasks and multiple computing nodes is characterized by comprising the steps that 1, each computing node reads a datum required by the current computing task of the node from a datum queue of a server and takes the datum as an input datum for node computing, wherein the datum in the data queue has a task identifier and a sequence mark; 2, each computing node takes a computing result as an output datum and outputs the computing result to the datum queue of the server, wherein the output datum has a task identifier and a sequence mark, the task identifier represents the task to which the datum is related, and the sequence mark shows the serial number of the datum in a related task. The method solves the problem of cooperation of multiple computing tasks and multiple computing nodes in one or more research and development groups.
