| * Engram CUDA hash kernel for O(1) N-gram context lookup. | |
| * | |
| * Phase 2: Custom CUDA kernel for batched hash computation. | |
| * Phase 1: Uses Python-level hashing in EngramModule._hash_context(). | |
| * | |
| * Hash function: h = token[t] ^ (token[t-1] * prime_1) ^ (token[t-2] * prime_2) | |
| * Output: h % n_columns (table index) | |
| * | |
| * This kernel parallelizes over (batch, sequence) dimensions. | |
