3. Compare the provided answer with the setting of the role and assess whether the answer can strictly adhere to the setting of the role.
4. Combine the results of the above assessment to give a fidelity score ranging from 1 to 5, where a score of 1 means that the response does not match the persona at all, and a score of 5 means that the response fully complies with the persona and satisfies the given request. | +| 简明扼要

Conciseness (1-5): answers should be concise and without redundant content. | 1. 阅读题目，提取出材料的重点。
2. 阅读该总结，并注意其中的主要观点和信息。
3. 评估总结的长度。一个简明扼要的总结通常应该在几句话或几段文字内传达关键信息，而不是冗长的段落或文章。
4. 检查总结是否包含与主要观点无关的信息或冗余信息。
5. 确定总结涵盖了材料中的关键信息，并且没有忽略任何重要细节。
6. 给总结打出 1-5 的分数，其中 5 表示总结简明扼要，没有冗余内容，而 1 表示总结冗长或包含不必要的信息，难以理解或记忆。根据您的判断，打出适当的得分。

1. Read the title and extract the main points of the material.
2. Read the summary and note the main ideas and messages in it.
3. Assess the length of the summary. A concise summary should usually convey key information within a few sentences or paragraphs, rather than lengthy paragraphs or essays.
4. Check that the summary does not contain information that is not relevant to the main ideas or that is redundant.
5. Make sure that the summary covers the key information in the material and that no important details have been omitted.
6. Rate the summary on a scale of 1-5, where 5 means the summary is concise and free of redundancy, and 1 means the summary is lengthy or contains unnecessary information that is difficult to understand or remember. Based on your judgment, assign the appropriate score. | GPT models evaluate the quality of model predictions based on the given prompt words and gives a score between 1-5. -> **NOTE 1:** Even for the same metric, the details of its prompt words and CoT(Chain-of-Thought) can differ based on which category you want to evaluate.

Download the dataset + +The dataset can be automatically downloaded by using `huggingface/datasets`. You can specify the dataset path by `-d` or `--dataset`.

For more details, please refer to [Booster plugins](https://colossalai.org/docs/basics/booster_plugins). +- Dataset path: `-d`, `--dataset`. The default dataset is `togethercomputer/RedPajama-Data-1T-Sample`. It support any dataset from `datasets` with the same data format as RedPajama. +- Number of epochs: `-e`, `--num_epochs`. The default value is 1. +- Local batch size: `-b`, `--batch_size`. Batch size per GPU. The default value is 2. +- Learning rate: `--lr`. The default value is 3e-4. +- Weight decay: `-w`, `--weight_decay`. The default value is 0.1. +- Warmup steps: `-s`, `--warmup_steps`. The default value is 2000. +- Gradient checkpointing: `-g`, `--gradient_checkpoint`. The default value is `False`. This saves memory at the cost of speed. You'd better enable this option when training with a large batch size. +- Max length: `-l`, `--max_length`. The default value is 4096. +- Mixed precision: `-x`, `--mixed_precision`. The default value is "fp16". "fp16" and "bf16" are supported. +- Save interval: `-i`, `--save_interval`. The interval (steps) of saving checkpoints. The default value is 1000. +- Checkpoint directory: `-o`, `--save_dir`. The directoty path to save checkpoints. The default value is `checkpoint`. +- Checkpoint to load: `-f`, `--load`. The checkpoint path to load. The default value is `None`. +- Gradient clipping: `--gradient_clipping`. The default value is 1.0. +- Tensorboard log directory: `-t`, `--tensorboard_dir`. The directory path to save tensorboard logs. The default value is `tb_logs`. +- Flash attention: `-a`, `--flash_attention`. If you want to use flash attention, you must install `flash-attn`. The default value is `False`. This is helpful to accelerate training while saving memory. We recommend you always use flash attention. + + +### 4.

Running environment +This experiment was performed on 4 computing nodes with 32 A800 GPUs in total. The nodes are +connected with RDMA and GPUs within one node are fully connected with NVLink. + +#### b.

High performance kernels and ops: which are inspired from existing libraries and modified correspondingly. +2. Efficient memory management mechanism：which includes the key-value cache manager, allowing for zero memory waste during inference. + 1. `cache manager`: serves as a memory manager to help manage the key-value cache, it integrates functions such as memory allocation, indexing and release. + 2. `batch_infer_info`: holds all essential elements of a batch inference, which is updated every batch. +3. High-level inference engine combined with `Shardformer`: it allows our inference framework to easily invoke and utilize various parallel methods. + 1. `engine.TPInferEngine`: it is a high level interface that integrates with shardformer, especially for multi-card (tensor parallel) inference: + 2. `modeling.llama.LlamaInferenceForwards`: contains the `forward` methods for llama inference. (in this case : llama) + 3. `policies.llama.LlamaModelInferPolicy` : contains the policies for `llama` models, which is used to call `shardformer` and segmentate the model forward in tensor parallelism way. + +## Pipeline of inference: + +In this section we discuss how the colossal inference works and integrates with the `Shardformer` .

The obtained results are as follows (due to time constraints, the evaluation has currently been performed solely on the `A100` single GPU performance; multi-GPU performance will be addressed in the future): + +### Single GPU Performance: + +Currently the stats below are calculated based on A100 (single GPU), and we calculate token latency based on average values of context-forward and decoding forward process, which means we combine both of processes to calculate token generation times. We are actively developing new features and methods to furthur optimize the performance of LLM models.
