Struct faiss::gpu::GpuIndexIVFScalarQuantizerConfig

struct GpuIndexIVFScalarQuantizerConfig : public faiss::gpu::GpuIndexIVFConfig

Public Members

bool interleavedLayout = true

Use the alternative memory layout for the IVF lists (currently the default)

IndicesOptions indicesOptions = INDICES_64_BIT

Index storage options for the GPU.

GpuIndexFlatConfig flatConfig

Configuration for the coarse quantizer object.

bool allowCpuCoarseQuantizer = false

This flag controls the CPU fallback logic for coarse quantizer component of the index. When set to false (default), the cloner will throw an exception for indices not implemented on GPU. When set to true, it will fallback to a CPU implementation.

int device = 0

GPU device on which the index is resident.

MemorySpace memorySpace = MemorySpace::Device

What memory space to use for primary storage. On Pascal and above (CC 6+) architectures, allows GPUs to use more memory than is available on the GPU.

bool use_cuvs = false

Should the index dispatch down to cuVS?
