    pub per_head_dim: usize,
    pub nheads: usize,
    pub mimo_rank: usize,
    pub num_rope_angles: usize,
}

Configuration / factory for a single Mamba3Cache.

Fields

batch: usize

Batch size.

state_rank: usize

State rank N.

per_head_dim: usize

Head dimension P.

nheads: usize

Number of SSM heads H.

mimo_rank: usize

MIMO rank R. 1 = SISO.

num_rope_angles: usize

Number of RoPE angle pairs = rope_dim / 2 = (state_rank * rope_fraction) / 2 (rounded down to even via Mamba3Config::rope_dim).
