Latency and Memory Analysis of Transformer Models for Training and Inference
### Overview
Many formulas or equations are floating around in papers, blogs, etc., about how to calculate training or inference latency and memory for Large Language Models (LLMs) or Transformers. Rather than doing math on papers or typing in Excel sheets, `let's automate the boring stuff with llm-analysis` :gear:!
Given the specified model, GPU, data type, and parallelism configurations, llm-analysis estimates the latency and memory usage of LLMs for training or inference. With llm-analysis, one can easily try out different training/inference setups theoretically, and better understand the system performance for different scenarios.
### Key Features
- **Model Configuration**: llm-analysis supports various model configurations, including LLaMA, Megatron-LM, and FasterTransformer models.
- **Latency and Memory Estimation**: It calculates the latency and memory usage based on the specified model, GPU, data type, and parallelism configurations.
- **Training/Inference Setup**: llm-analysis helps determine the optimal batch size, data type, parallelism scheme, and other parameters for training or inference.
- **Benchmarking**: It provides a benchmark for different setups, helping to understand the performance impact of various factors.
### Tech Stack
- Python
### Why It Matters
Understanding the performance of LLMs and Transformers is crucial for optimizing training and inference setups. llm-analysis simplifies the process by automating the calculations, making it easier to experiment with different configurations and quickly assess the impact on latency and memory usage.
