It is now down to 2%. Strangely enough, I measure 13.6 t/s with llama-bench, but if I let the model give me an actual response with llama-cli, I get close to 17 t/s. * Fix CPU scale: 13.6 -> 16.7 t/s for Qwen3Next For Qwen3Next there is a scale op on a largish tensor (548k elements) that has a single row for TG, so was done in a single thread. We now simply use blocks of 1024 elements. * Optimize CPU mul: 16.7 -> 17.6 t/s for Qwen3Next * CPU: fuse transpose -> cont -> sum_rows -> transpos: 17.6 -> 23.1 t/s for Qwen3Next * Optimize CPU repeat: 176 -> 200 t/s for Qwen3Next PP-512 * Multithreading for OP_SUB * Don't commit with timing trace on * Multithread neg and sigmoid * Be able to turn on/off fusion more easily (CPU) * Name the mul_mat ops so we know where the time goes * WIP * Much better PP on CUDA * CUDA: fuse transpose -> cont -> sum_rows -> transpose Needs non-coontiguous variant of sum_rows. On the CPU this gave 30+% improvement in TG performance, on CUDA ist is disapointing 6-7%. I guess, this is because Georgi's cont CPU implementation was so bad that skipping it made such a big difference. * CUDA: faster mul for special case relevant for Qwen3Next Worth 1% in TG * Fix CPU OP_CONT --------- Co-authored-by: yurko <yurko@local> Co-authored-by: Yurko <yurko@example.com> Co-authored-by: yurko <yurko@pop-os.tail5a1a6b.ts.net> Co-authored-by: Yurko Hoshko <YurkoHoshko@users.noreply.github.com>
