gpu basics techIn `cuda_runtime.h`, there are several APIs for retrieving properties for the installed GPU. cudaDeviceGetAttribute(int* value, cudaDeviceAttr attr, int device): a C api cudaGetDeviceProperties ( cudaDeviceProp* prop, int device ) : a C++ api Here is the code of the example. On a Nvidia GTX 3080 GPU, the properties are as below: Device 0 properties: Max block dimensions: 1024 x 1024 x 64 Max grid dimensions: 2147483647 x 65535 x 65535 Shared memory bank size: 4 bytes Max shared memory per block: 49152 bytes Max registers per block: 65536 Warp size: 32 Multiprocessor count: 68 Max resident threads per multiprocessor: 1536 = 48 warps L2 cache size: 5242880 bytes Global L1 cache supported: yes Total global memory: 9 GB Processor clock: 1 MHZ Memory clock: 9 MHZ
