The embodiment of the invention provides a write request processing method, an IO agent module, a Slave agent module and a computer system. The method applied to the IO agent module comprises the steps that an IO write request of an IO module is obtained; determining the cache line coverage integrity corresponding to the cache line write operation of the IO write request; based on the cache line coverage integrity of the cache line write operation, sending an exclusive permission request of a cache line corresponding to the cache line write operation; when the sending sequence of the IO write requests arrives, if the exclusive authority of the cache line corresponding to the cache line write operation of the IO write requests is acquired, sending a complete write data request corresponding to the cache line write operation based on complete write data corresponding to the cache line; the complete write data request is used for requesting to write complete write data in the cache line, and the complete write data at least comprises write data of write operation of the cache line. According to the embodiment of the invention, the order-preserving requirement of the transmission network can be released under the condition that the data consistency is guaranteed, and the performance of the transmission network is improved.

The invention discloses a flow battery distribution area design method, which comprises the following steps of: formulating a corresponding flow channel distribution area hierarchical structure according to a flow channel distribution type; determining the number of transfer stations of the electrolyte distribution area of each level in the hierarchical structure of the flow channel distribution area, and designing that the total through-flow sectional area of each branch between the transfer stations of two adjacent levels is consistent; according to the total through-flow sectional area of each branch of any transfer station in the electrolyte distribution area and the number and confluence condition of all branches connected with the liquid outlet end of the transfer station, the through-flow amount of each branch is calculated, and then the through-flow sectional area and the through-flow length of the corresponding branch are designed according to the through-flow amount of the branch.
