The invention discloses a process management method and device. On one hand, progresses to be executed are grouped according to the execution time of the progresses to be executed and used shared resources, the execution times of progresses in the same group of the progress groups formed after grouping are in the same time period, and progresses in the same progress group do not have the characteristic of shared resource confliction; on the other hand, the execution time of each progress group is determined, and the progresses to be executed in each progress group are executed with the progress groups as units according to the execution time of each progress group. Therefore, the problem of shared resource confliction during parallel processing of multiple threads in the prior art can be effectively solved, a locking state or the situation that the progresses to be executed are in a long-time waiting state is avoided, and accordingly the progress processing efficiency is improved.
