The invention provides a data processing method and device and a storage medium. The method comprises the following steps: an electronic device receiving a calculation instruction input by a user fora to-be-calculated item, and determining a plurality of sub-projects corresponding to the to-be-calculated project according to a first mapping relation between the to-be-calculated project and the sub-projects, obtaining the current CPU occupancy rate of each available computing node in real time, and sequentially distributing the computing tasks of the sub-projects to each corresponding computing node according to the sequence of the CPU occupancy rates from low to high; and when it is monitored that each computing node completes the computing task of the sub-project, obtaining a computing result that each computing node executes the computing task of the sub-project; summarizing and calculating the obtained calculation results obtained by the calculation nodes according to a preset formula to obtain a summarized calculation result. By utilizing the method and the system, node sharing and decentralization can be realized, and the system availability and the operation efficiency are improved.
