Enum P64ConvertLayout 

Source 
pub enum P64ConvertLayout {
    Verbatim,
    F16Expand,
    Q4kSoa,
}
Expand description

Conversion-time weight layout policy for compile_gguf_to_p64_with_layout.

The designed product path is: import GGUF once → store GPU-friendly bytes in .p64. P64ConvertLayout::Verbatim is the historical byte-preserving container swap (same kernels, same speed). P64ConvertLayout::F16Expand dequantizes 2-D weight matrices to IEEE f16 so decode can use the fast unpack2x16float path. P64ConvertLayout::Q4kSoa rewrites Q4_K matrices to a 160 B/superblock SoA with pre-expanded f16 sub-scales (decode GEMV skips scale unpack + header barriers).

Variants§

§

Verbatim

Copy GGML quant blocks byte-for-byte (no speed change vs running the GGUF).

§

F16Expand

Expand 2-D matrices (attn/FFN/embd/output) to f16; leave 1-D norms as source. Rejected if the result would exceed the 4 GiB u32-offset container limit.

§

Q4kSoa

Convert 2-D Q4_K weight matrices to crate::ggml_quants::GGML_TYPE_Q4_K_SOA. Other tensors stay verbatim. ~11% larger than Q4_K; aimed at 3B-class decode.
