Introducing the πŸ€— Transformers.js WebGPU Embedding Benchmark! ⚑️
πŸ‘‰ Xenova/webgpu-embedding-benchmark πŸ‘ˆ

On my device, I was able to achieve a 64.04x speedup over WASM! 🀯 How much does WebGPU speed up ML models running locally in your browser? Try it out and share your results! πŸš€

Very impressive. Curious how to enable WebGPU?

Understanding WebGPU, WASM, and Benchmarks for BERT-Based Models
What is WebGPU?
WebGPU is an emerging web standard designed to provide modern 3D graphics and computation capabilities on the web. It acts as a successor to WebGL, offering a more powerful and flexible interface that allows web developers to access the GPU for complex graphics rendering and high-performance computing tasks directly. This is particularly useful for applications requiring significant computational power, such as machine learning models, complex simulations, and advanced game graphics.

What is WASM (WebAssembly)?
WebAssembly (WASM) is a binary instruction format for a stack-based virtual machine. WASM is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications. It’s incredibly efficient and fast, making it suitable for performance-critical applications like video and audio processing, games, and, importantly for this context, machine learning models. It allows code written in languages like C, C++, and Rust to run on the web at near-native speed.

Benchmarking BERT-Based Embedding Models with WebGPU and WASM
BERT (Bidirectional Encoder Representations from Transformers) is a sophisticated model used in natural language processing (NLP) for a variety of tasks like translation, summarization, and sentiment analysis. Benchmarking BERT-based models using WASM and WebGPU involves evaluating the performance of these models when executed using WebAssembly and WebGPU technologies. Here’s a detailed breakdown of how this benchmarking works:

Execution Providers:

WebGPU Execution Provider: This refers to using the WebGPU API to run computations necessary for the BERT model directly on the GPU. This setup is expected to leverage the parallel processing capabilities of GPUs to accelerate tasks significantly.
WASM Execution Provider: This involves running the BERT model computations within a WebAssembly environment. While generally faster than JavaScript, WASM execution speed will depend on the complexity of tasks and the efficiency of the WASM module.
Measurement of Execution Time:

The primary metric for this benchmark is the execution time, specifically how long it takes to process different batch sizes of data using BERT-based models. A batch size refers to the number of data samples processed before the model updates its state. Common batch sizes might range from small (e.g., 1-10) to large (100s).
Comparing Across Batch Sizes:

The benchmark will likely run multiple tests where each test uses a different batch size. This is crucial as it shows how well the execution scales with increasing data volumes. It's particularly interesting in machine learning as larger batch sizes generally provide more stable and reliable gradient updates in training - but they require more memory and computational power.
Interpretation:

The results from this benchmark can help developers and researchers determine which execution provider is more suitable for specific tasks in terms of speed and efficiency. For instance, WebGPU might be faster for larger batch sizes due to better GPU utilization, while WASM might be preferred for scenarios where compatibility and quick loading are priorities.
Application:

Understanding these benchmarks helps in optimizing web-based applications that use BERT for tasks such as embedding extraction, where performance directly influences user experience and operational costs.
This kind of benchmarking is vital for developers in the web domain to optimize applications to achieve the best performance using various technologies available (like WebGPU and WASM) depending on the application needs and available resources.
