A highly optimized, cost-effective batch embedding engine capable of processing hundreds of millions of texts in minutes on multi-GPU setups, specifically addressing CPU-GPU bottleneck issues in high-throughput inference.
IgniteMS addresses a critical performance bottleneck in large-scale text embedding: the CPU's inability to feed data fast enough to multi-GPU setups. By leveraging Rust and TensorRT, this engine achieves unprecedented throughput (685M texts in 32 minutes on 8x A100s) at a significantly reduced cost ($7 per run on spot instances). This optimization is crucial for data-intensive AI applications requiring rapid, cost-efficient vector database population or large-scale data preprocessing. The market implication is a demand for highly specialized, low-level inference engines that maximize hardware utilization and minimize operational expenses. This trend underscores the need for engineering expertise beyond Python-centric AI development to unlock true scale and efficiency in foundational AI tasks.
Quick note on how it works and how I've done my batch embedding engine IgniteMS.The whole thing runs as one process using Rust, reading input, tokenizing, packing batches, keeping the queue full. TensorRT handles inference. Python is only as a wrapper.I built it this way because when you use more than couple of GPUs, the GPUs stop being the problem. CPU cannot feed them fast enough. One A100 can go through batches faster than Python can tokenize and feed, so the GPU just sits there idle waiting for work. Most of my time went into optimizing this. At 8 GPUs that was basically the entire challenge.On cost. I ran the big 2B messages job on a spot p4d instance (8x A100 40GB). After filtering and dedupping I got 685M raw texts. With my new engine the whole production run finishes in about half an hour. Previously I used on-demand for these jobs, now switched to spots. If AWS reclaims the box, I just rerun it. It's roughly $7 for half-an-hour run. And at least right now spots are easier to get than on-demand.Open warning: it's batch only and NVIDIA only. You can use it both as a docker image and native.
I used some optimizations for my production run. With default settings you can expect to see ~250K msg/sec if you run the benchmark script on your p4d box.
