IndicesOptions indicesOptions = INDICES_64_BIT

how should indices be stored on index types that support indices (anything but GpuIndexFlat*)?

bool useFloat16CoarseQuantizer = false

is the coarse quantizer in float16?

bool useFloat16 = false

for GpuIndexIVFFlat, is storage in float16? for GpuIndexIVFPQ, are intermediate calculations in float16?

bool usePrecomputed = false

use precomputed tables?

long reserveVecs = 0

reserve vectors in the invfiles?

bool storeTransposed = false

For GpuIndexFlat, store data in transposed layout?

bool verbose = false

Set verbose options on the index.

bool use_raft = false

use the RAFT implementation
