Abstract: Disclosed by embodiments of the present application are a data caching method, a data processing method, a computer device and a storage medium. The method comprises: obtaining virtual location information of a virtual data buffer of a virtual network interface assembly; designating entity location information of an entity data buffer of an entity network interface assembly as the virtual location information; and when storing data in the entity data buffer, storing according to the virtual location information. Since entity location information of an entity data buffer of an entity network interface assembly is designated as virtual location information, rather then being determined by means of physical device allocation, after data is received, the entity network interface assembly may store the data to a data buffer designated by a virtual network interface assembly, thereby avoiding the process of copying data from a data buffer designated by an entity network interface assembly to a data buffer designated by a virtual network interface assembly, and reducing time consumption for receiving data, improving the network performance of data reception, and reducing network delay.

Abstract: A rotary drying-type stir fry method, in which a rotatable pot (1) is provided, the inner wall of the pot (1) being provided with at least one blade (11); solid rice grains (A) that are 60-100% cooked are then placed in the pot (1); a liquid sauce (B) the weight of which is 48-52% that of the solid rice grains (A) is added into the pot (1) and mixed; the rice mass is rotated in the pot (1) at a set time and rotary speed and at a certain temperature, and a high temperature will gradually dry up the water content of the liquid sauce (B) in the rice mass and continuously cook the rice grains until the water content in the rice mass has evaporated. Since the water content is reduced, the rice grains in the rice mass are fully cooked and stickiness is reduced so as to appear in a loose, dried and cooked stir fried state, thus obtaining a delicious stir fry in which rice grains that are not completely cooked undergo high-temperature frying to appear loose and not stick together, such that the grains are distinct, bright and plump.
