Struct SwaPattern 

pub struct SwaPattern {
    pub period: usize,
    pub dense_first: bool,
}

llama.cpp’s hardcoded alternating sliding-window layout for one architecture: the period, and which end of each period is the full-attention layer.

llama_hparams::set_swa_pattern (src/llama-hparams.cpp:8-22) has two phases, and they are not interchangeable:

• dense_first = false: is_swa[il] = il % p < (p - 1) — the last layer of every period is full attention.
• dense_first = true: is_swa[il] = il % p != 0 — the first layer of every period is full attention.

For a 32-layer period-4 model the two disagree on 16 of the 32 layers. Storing only the period would therefore not be a partial transcription, it would be a wrong one for the four architectures llama.cpp passes dense_first = true.

Fields

period: usize

llama.cpp’s swa_period seed literal.

dense_first: bool

llama.cpp’s dense_first argument to set_swa_pattern.
