This invention belongs to the field of sparse matrix solving, specifically involving a SpMV optimization method based on heterogeneous platforms. The method first reads the sparse matrix data and constructs a compressed sparse row storage format for the matrix. Then, using matrix rows as clustering objects, hierarchical clustering and row / column rearrangement are performed based on global and local density features to form dense and sparse sub-blocks suitable for execution on heterogeneous platforms. Dynamic task scheduling is then combined to achieve load balancing between the CPU and DCU. Furthermore, to address the memory access bottleneck of the DCU platform, an LDS double-buffering mechanism is constructed, overlaying data transport and computation processes to reduce global memory access latency. Simultaneously, to address the Bank conflict problem in LDS shared storage, a joint optimization strategy based on padding and transpose access is designed to reduce the probability of conflicts during concurrent access by thread bundles. In addition, in multi-DCU collaborative scenarios, asynchronous communication and computation overlap mechanisms reduce intra-device synchronization waiting and communication overhead.
