commit 336c75d Author: Mark Lee <markblee@apple.com> Date: Mon Mar 3 09:04:07 2025 -0800 Supports arbitrary uniform partitioning in host-global array conversions. (apple#1029) * Allows specifying PartitionSpec to host_to_global_device_array. * Generalizes to arbitrary uniform partitioning. * Addresses comments and adds mixed shape test. commit 0881412 Author: Dongseong Hwang <dhwang2@apple.com> Date: Sat Mar 1 15:41:38 2025 -0800 Refactor Mask in Attention (apple#1028) Currently, the attention code is **hardcoded** to handle either `causal_mask` or an arbitrary `mask_fn`. To support **sliding window masks**, we previously used a **hack** by injecting the `_sliding_window_size` attribute into functions. This refactor **makes the masking logic more flexible** by allowing arbitrary `MaskFnAttentionBias`. - If downstream requires a **new mask pattern**, they can simply: 1. Implement a **subclass of `MaskFnAttentionBias`**. 2. Set `attention.mask` accordingly. commit f67d3f9 Author: Dongseong Hwang <dhwang2@apple.com> Date: Fri Feb 28 08:53:00 2025 -0800 Flash Attention now explicitly checks whether it is in decoding mode. (apple#1026) Currently, Flash Attention infers decoding implicitly based on circumstantial evidence. This PR makes the check explicit. commit f8d2c66 Author: qdavid1 <168590940+qdavid1@users.noreply.github.com> Date: Thu Feb 27 15:26:18 2025 -0800 External KV input for _update_layer_kwargs (apple#1025) commit a3bf5e2 Author: Hanzhi Zhou <hanzhi_zhou@apple.com> Date: Wed Feb 26 17:23:40 2025 -0800 Minor changes to Checkpointer (apple#1024) commit 55e1841 Author: Wentao Wu <wentao_wu@apple.com> Date: Wed Feb 26 15:45:51 2025 -0800 Add an option to break ties for top_k_logits when k = 1 (apple#1022) * Add an option to support stable top_k = 1. * address comments * address comments * address comments * Update axlearn/common/logit_modifiers.py Co-authored-by: Mark Lee <markblee@apple.com> * Update axlearn/common/logit_modifiers.py Co-authored-by: Mark Lee <markblee@apple.com> * Update axlearn/common/logit_modifiers.py Co-authored-by: Mark Lee <markblee@apple.com> * Update axlearn/common/logit_modifiers.py Co-authored-by: Mark Lee <markblee@apple.com> * address comments --------- Co-authored-by: Mark Lee <markblee@apple.com> commit fbca3fc Author: Meng (Ethan) Li <ethanli@apple.com> Date: Wed Feb 26 14:05:25 2025 -0800 Add priority_class as a launch flag (apple#1020) commit b26bd74 Author: Meng (Ethan) Li <ethanli@apple.com> Date: Wed Feb 26 14:04:47 2025 -0800 Fix TypeError in calcualte_goodput.py (apple#1023) commit f8191e1 Author: Dongseong Hwang <dhwang2@apple.com> Date: Wed Feb 26 11:03:44 2025 -0800 Emulate flash attentnion unittests on CPU. (apple#1021) utils.py codebase is not well covered by CI because it branches different backend. This PR introduces new CPU test, utils_test.py. This test is expected to run on CPU and is designed to validate GPU/TPU code from a CPU environment by fake mesh. It allows quick verification in CI and local environments to ensure that code changes do not break GPU/TPU Flash Attention. commit daec8c5 Author: Chang Liu <raytomato@users.noreply.github.com> Date: Tue Feb 25 12:38:43 2025 -0800 Add additional_network and additional_subnetwork config to support multi-nic for v6e (apple#1019) Co-authored-by: Chang Liu <changliu@apple.com> commit ac642ea Author: Dongseong Hwang <dhwang2@apple.com> Date: Tue Feb 25 12:02:57 2025 -0800 Fix crash in log-mel frontend when waveform samples are integers. (apple#1017) After updating JAX, this existing hidden bug started causing CI failures. When the sample dtype is int32 (which is valid), `jnp.finfo` returns None, even though `jnp.iinfo` is available. The previous JAX version seemed to handle this case more forgivingly. ``` ../axlearn/axlearn/audio/frontend_utils.py:297: in linear_to_log_spectrogram return jnp.log(jnp.maximum(x, jnp.finfo(x.dtype).tiny)) ``` commit 7c64b55 Author: Meng (Ethan) Li <ethanli@apple.com> Date: Tue Feb 25 10:52:50 2025 -0800 Add LoadBalancer to GKE replicatedJob (apple#1015) Co-authored-by: Liang (SPG) He <lhe27@apple.com> commit 8e8a41b Author: Chang Lan <c.lan@apple.com> Date: Tue Feb 25 10:26:59 2025 -0800 Expose jax.lax.scan's unroll option to Repeat layer (apple#1016) * Expose jax.lax.scan's unroll option to Repeat layer. * Defaults to None to avoid golden config changes commit 682bce6 Author: Dongseong Hwang <dhwang2@apple.com> Date: Tue Feb 25 10:09:41 2025 -0800 Handle None bias in BiasAndResidual (apple#1018) commit f053318 Author: Ruoming Pang <ruoming@gmail.com> Date: Mon Feb 24 11:12:23 2025 -0500 Allows a required value in a config_for_{function,class} to be specified via **kwargs in instantiate().

(apple#995) * Revert "Transpose kv cache for better decode performance (apple#979)" This reverts commit b130416. * Update golden configs * Implemented sliding window attention to maintain KV cache only for the window size to enable infinite decoding. Currently, when using `MultiheadAttention` or `GroupedQueryAttention` for sliding window attention, the KV cache is kept for the full sequence length (`seq_len`) instead of the window length (`window_len`). For example, a model with `window_len=1k` and `seq_len=2M` keeps a KV cache for the full 2M tokens. It then biases 1999k invalid KV tokens before calculating attention, resulting in a computational complexity of **O(2M²)** instead of the desired **O(1k²)**. This issue persists even when using flash attention. Flash attention uses the KV cache allocated in HBM as its input. While unnecessary blocks are discarded during computation, the KV cache still occupies HBM inefficiently for the full 2M tokens. To address this, when `MultiheadAttention` detects a sliding window mask, it stores the key-value (KV) cache in a ring buffer inside the input linear layer. As a result, downstream projects using `MultiheadAttention` automatically benefit from efficient KV cache handling in `init_states` and `extend_step`. Additionally, for use cases like local-global attention in LLMs, it is recommended to use sliding window masks for even the global attention as well. For example, if you want to train an LLM with a context length of 8k, you can set the sliding window size to 8k during training. This enables functionally infinite decoding during inference. Accuracy wouldn't be good tho. Note: * query_positions in QKVLinear.forward() was introduced by apple#914. Now it returns to the caller.

(apple#936) commit ac7a3ed Author: Dongseong Hwang <dhwang2@apple.com> Date: Thu Jan 23 08:15:27 2025 -0800 Enabled running Pallas Flash Attention on CPU. (apple#922) Pallas supports CPU simulation (`interpret=True`), so we can use the same TPU Pallas kernel on CPU — making code debugging easier. This change lets the following unittests run on CPU as if they were on TPU, enabling easier testing and debugging: - `axlearn/common/flash_attention/tpu_attention_test.py` Similarly, `gpu_attention_test.py` can also be run on CPU as if they were on GPU. - `axlearn/common/flash_attention/gpu_attention_test.py` Now CI covers those tests on CPU as well.

However the actual HBM saving would be limited in the model-parallel setting, as the heads are already sharded across devices. It also introduces some limitation which breaks some of the existing sharding configurations. For example, let's say num_heads = 8 and num_kv_heads = 4. When we repeat KV heads, we can set the model axis as 8 so that each device will have only one Q, K, V head; Without repeat_kv_heads, the max value of model axis is 4, and each device will have 2 Q heads as a result, increasing the actual HBM usage. * Repeat kv as necessary for sharding * Unit tests * Address comments. commit 4678740 Author: Chang Lan <c.lan@apple.com> Date: Mon Jan 20 20:36:44 2025 -0800 AOT compilation for v6e (apple#937) commit 357bef6 Author: Mark Lee <markblee@apple.com> Date: Mon Jan 20 20:23:39 2025 -0800 Makes causal lm metrics configurable.

To support **sliding window masks**, we previously used a **hack** by injecting the `_sliding_window_size` attribute into functions. This refactor **makes the masking logic more flexible** by allowing arbitrary `MaskFnAttentionBias`. - If downstream requires a **new mask pattern**, they can simply: 1. Implement a **subclass of `MaskFnAttentionBias`**. 2. Set `attention.mask` accordingly. commit f67d3f9 Author: Dongseong Hwang <dhwang2@apple.com> Date: Fri Feb 28 08:53:00 2025 -0800 Flash Attention now explicitly checks whether it is in decoding mode.

(apple#995) * Revert "Transpose kv cache for better decode performance (apple#979)" This reverts commit b130416. * Update golden configs * Implemented sliding window attention to maintain KV cache only for the window size to enable infinite decoding. Currently, when using `MultiheadAttention` or `GroupedQueryAttention` for sliding window attention, the KV cache is kept for the full sequence length (`seq_len`) instead of the window length (`window_len`). For example, a model with `window_len=1k` and `seq_len=2M` keeps a KV cache for the full 2M tokens. It then biases 1999k invalid KV tokens before calculating attention, resulting in a computational complexity of **O(2M²)** instead of the desired **O(1k²)**. This issue persists even when using flash attention. Flash attention uses the KV cache allocated in HBM as its input. While unnecessary blocks are discarded during computation, the KV cache still occupies HBM inefficiently for the full 2M tokens. To address this, when `MultiheadAttention` detects a sliding window mask, it stores the key-value (KV) cache in a ring buffer inside the input linear layer. As a result, downstream projects using `MultiheadAttention` automatically benefit from efficient KV cache handling in `init_states` and `extend_step`. Additionally, for use cases like local-global attention in LLMs, it is recommended to use sliding window masks for even the global attention as well. For example, if you want to train an LLM with a context length of 8k, you can set the sliding window size to 8k during training. This enables functionally infinite decoding during inference. Accuracy wouldn't be good tho. Note: * query_positions in QKVLinear.forward() was introduced by apple#914. Now it returns to the caller.

(apple#936) commit ac7a3ed Author: Dongseong Hwang <dhwang2@apple.com> Date: Thu Jan 23 08:15:27 2025 -0800 Enabled running Pallas Flash Attention on CPU. (apple#922) Pallas supports CPU simulation (`interpret=True`), so we can use the same TPU Pallas kernel on CPU — making code debugging easier. This change lets the following unittests run on CPU as if they were on TPU, enabling easier testing and debugging: - `axlearn/common/flash_attention/tpu_attention_test.py` Similarly, `gpu_attention_test.py` can also be run on CPU as if they were on GPU. - `axlearn/common/flash_attention/gpu_attention_test.py` Now CI covers those tests on CPU as well. In M3 Max MacBook Pro, test coverages and processing time are as follows, * axlearn/common/flash_attention/gpu_attention_test.py: 3024 passed, 1345 skipped in 200.38s (0:03:20) * axlearn/common/flash_attention/tpu_attention_test.py: 18 passed, 435 skipped in 34.82s commit 8ea85bd Author: Hanzhi Zhou <hanzhi_zhou@apple.com> Date: Wed Jan 22 09:51:15 2025 -0800 Some fixes for flash remat (apple#942) commit 185b1b5 Author: Chang Lan <c.lan@apple.com> Date: Tue Jan 21 11:21:08 2025 -0800 Repeat KV heads in Flash Attention (apple#938) * Roll back '_repeat_kv_heads' change in Flash Attention Recent PR removed _repeat_kv_heads from Flash Attention for GQA optimization, in the hope to reduce HBM usage. However the actual HBM saving would be limited in the model-parallel setting, as the heads are already sharded across devices. It also introduces some limitation which breaks some of the existing sharding configurations. For example, let's say num_heads = 8 and num_kv_heads = 4. When we repeat KV heads, we can set the model axis as 8 so that each device will have only one Q, K, V head; Without repeat_kv_heads, the max value of model axis is 4, and each device will have 2 Q heads as a result, increasing the actual HBM usage. * Repeat kv as necessary for sharding * Unit tests * Address comments. commit 4678740 Author: Chang Lan <c.lan@apple.com> Date: Mon Jan 20 20:36:44 2025 -0800 AOT compilation for v6e (apple#937) commit 357bef6 Author: Mark Lee <markblee@apple.com> Date: Mon Jan 20 20:23:39 2025 -0800 Makes causal lm metrics configurable.
