set_default_chunk_size

set_default_chunk_size(chunk_size)

Set the default chunk size for chunked FFT convolutions.

Smaller chunk sizes use less memory but have more overhead. Recommended: 128 for best speed/memory trade-off (~11% overhead, ~26% savings). Use 64 for more aggressive memory savings (~27% overhead, ~35% savings).

Parameters:

chunk_size (int) – Number of channels to process at once.

Return type:

None
