全局批大小(Global Batch Size)指的是在一次迭代(iteration)中用于训练模型的总样本数。在分布式训练中,这个参数特别重要,因为它涉及到多个计算节点(或GPU)之间的数据分配和并行计算。 全局批大小的计算公式通常是: Global Batch Size = (Number of GPUs or Nodes)×(Local Batch Size per GPU or Node) 其中,Lo...
总的来说,Micro-Batch Size 越小,MFU 越高;当 Micro-Batch Size 大于 2 时,具有 8K 序列长度的模型无法通过任何并行配置来适应 GPU 显存。 因此,我们得出结论,在大多数情况下选择 Micro-Batch Size 为 1 是最优的。Micro-Batch Size 为 1 的最佳表现可以归因于以下三个因素。 最小的模型并行度:通常高效...
micro batch slice 可能导致数据的上下文丢失 (e.g. 序列生成任务中),需要保证切片后每个 micro batch 的数据仍然是独立的。 3. 通讯开销 在多GPU 场景中,如果每一个 micro batch 都需要与其他 GPU 通信,会带来额外的通信开销 5. 应用场景 大模型训练 :分布式训练中,通过 micro batch 和 梯度累积来减少显存...

他们凭借专家和 GPU 能力在 ML 领域占据主导地位。为了给人一种规模感,最好的人工智能,比如谷歌翻译使用的人工智能,需要几个月的训练。他们并行使用数百个高性能 GPU。TinyML 通过变小来扭转局面。由于内存限制,大型 AI 模型不适合微控制器。下图显示了硬件要求之间的差异。
When an algorithm is automatically selected by cuDNN, the decision is performed on a per-layer basis, and thus it often resorts to slower algorithms that fit the workspace size constraints. We present {\mu}-cuDNN, a transparent wrapper library for cuDNN, which divides layers' mini-batch ...
Tests were performed using batch size 56 and 2048 input tokens and 2048 output tokens for Mistral-7B Configurations: 2P AMD EPYC 9534 64-Core Processor based production server with 8x AMD InstinctTM MI300X (192GB, 750W) GPU, Ubuntu® 22.04.1, and ROCm™ 6.1.1 ...
GPU-based configurations. Despite the promising results, GASPP may suffer from high packet processing latency due to the batch processing nature of GPUs. In other words, GASPP is not tailored to lead with applications that rely on a per-packet basis processing such as intrusion detection or ...
