On A100, CUDA 11 offers API operations to set aside a portion of the 40-MB L2 cache to persist data accesses to global memory. Persisting accesses have prioritized use of this set-aside portion of L2 cache, whereas normal or streaming accesses to global memory can only use this portion of...

修改L2 cache 的persistent size The L2 cache set-aside size for persisting accesses may be adjusted, within limits: cudaGetDeviceProperties(∝, device_id); cudaDeviceSetLimit(cudaLimitPersistingL2CacheSize, prop.persistingL2CacheMaxSize); / * Set aside max possible size of L2 cache for persisting...

For more details refer to the L2 Access Management section in the CUDA C++ Programming Guide. 9.2.2.1. L2 Cache Access Window When a CUDA kernel accesses a data region in the global memory repeatedly, such data accesses can be considered to be persisting. On the other hand, if the...
