Enum OpClass 

pub enum OpClass {
    Ffn = 0,
    Matvec = 1,
    Matmat = 2,
    Batch = 3,
    MatmatWide = 4,
}

GPU-eligible op classes, each with an independent probe.

Variants

Ffn = 0

Whole FFN chain in one submission (dense / MoE block).

Matvec = 1

Large hybrid CPU∥GPU matvec (lm_head class).

Matmat = 2

Prefill GEMM (matmat).

Batch = 3

Batched matvecs of one input (QKV).

MatmatWide = 4

Prefill GEMM at image-diffusion widths (b ≥ 128). Probed apart from Matmat: one imagegen process runs BOTH populations (prompt encode b≈40 where the GPU wins big, DiT b≥256 where the CPU AMX arm is competitive) — a single shared verdict locks the wrong arm for whichever population samples second.
