Detailed Description

C-Kernel-Engine Parity Testing API.

Exposes individual CK kernels for parity testing against llama.cpp/ggml. This API mirrors the test-kernel-parity.cpp interface in llama.cpp.

Usage:

1. Build as shared library: libck_parity.so
2. Load from Python using ctypes
3. Call functions with matching signatures to test-kernel-parity.cpp

Multi-head causal attention for prefill (head-major layout)

Layout (head-major, matches llama.cpp test): Q: [num_heads, tokens, head_dim] K: [num_kv_heads, seq_len, head_dim] V: [num_kv_heads, seq_len, head_dim] out: [num_heads, tokens, head_dim]

Supports GQA (grouped-query attention) where num_heads > num_kv_heads. Causal masking: token t can only attend to positions 0..t (inclusive).

k	Key [num_kv_heads, seq_len, head_dim]
v	Value [num_kv_heads, seq_len, head_dim]
out	Output [num_heads, tokens, head_dim]
num_heads	Number of query heads
num_kv_heads	Number of key/value heads (for GQA)
tokens	Number of query tokens
seq_len	Key/value sequence length (for prefill: seq_len == tokens)
head_dim	Dimension per head

     * This is different from gemv_q4_k_q8_k() and gemv_q5_0_q8_0() which are
     * "quantized dot product" kernels that take block_q8_K or block_q8_0 input.
     *
     * WHY THIS IS ERROR-PRONE:
     *   When copying from ck_test_gemv_q5_0() (which calls gemv_q5_0_q8_0),
     *   it is natural to assume Q5_K also needs pre-quantization. But the
     *   function name tells you: gemv_q5_k() takes float*, while
     *   gemv_q5_0_q8_0() takes block_q8_0*. If the kernel name does not
     *   have "_q8_0" or "_q8_k" suffix, it expects FP32 input.
     *
     * PARITY NOTE:
     *   llama.cpp reference uses ggml_vec_dot_q5_K_q8_K which quantizes
     *   the input to Q8_K internally. Our FP32 path will have slightly
     *   different numerical results. Use tolerance ~1e-2 for comparison.
