GPU Pro Tip: Fast Dynamic Indexing of Private Arrays in CUDA

WebFeb 11, 2015 · Uniform access with truly dynamic indexing causes the compiler to use local memory for the array. If 1) you have sufficient math instructions in the kernel to hide local load/store latency and 2) private arrays fit into L2/L1 caches, then the performance hit due to these additional loads/stores should be small. WebGPU: [1, min(2048, nlist)] IVF_SQ8 IVF_FLAT does not perform any compression, so the index files it produces are roughly the same size as the original, raw non-indexed vector data. For example, if the original 1B SIFT dataset is 476 GB, its IVF_FLAT index files will be slightly larger (~470 GB).
