Document Type and Number:
WIPO Patent Application WO/2024/051041
Kind Code:
A9
Abstract:
A data access method, an apparatus, a device, and a computer-readable storage medium, the method comprising: creating at the host side a cache pool matching memory capacity of an accelerator card, the cache pool comprising cache blocks divided according to a set capacity unit; in the case of acquiring a reading instruction of target data, calling from the cache pool a target cache block matched with the capacity of the target data; storing the target data into the target cache block, recording meta information of the target cache block, and setting write protection for the target cache block; and executing data access operation according to the state information corresponding to each cache block, and regulating the state information of the cache blocks after executing the data access operation. The present invention can avoid repeated transmission of the same data between the host side and the accelerator card; since the cache blocks are continuous large block memory, the method requires few transmission descriptors and can continuously transmit a large amount of data at a time, thereby improving the utilization rate of bandwidth and improving the efficiency of data transmission.
