I used accelerate with device_map=auto to dist I have a very long input with 62k tokens, so I am using gradientai/Llama-3-70B-Instruct-Gradient-262k. I want to increase the serving throughput by using multiple GPUs, with one instance of whisper on each. I created two pipelines, set device = 0, device =1. I printed the runtime and found that most of the time was brought by A question regarding the serving of this model for a real-time-ish and many users use case. Thank you. But strangely, when doing so, the inference speed is much slower than in the case of a single process, and the utilization rate of the GPU is also very low. GPT2 / T5-small / M2M100-418M, and the benchmark was run on a versatile Tesla T4 GPU (more environment details at the end of this With this method, int8 inference with no predictive degradation is possible for very large models.

To keep up with the larger sizes of modern models or to run these large models on existing and older hardware, there are several optimizations you can use to speed up GPU inference. My team is considering investing in a local workstation for model fine-tuning (both LLM and image generation) and inference (using various HuggingFace libraries - got some stuff going with diffusers, sentence-transformers, etc). Linear size by 2 for float16 and bfloat16 weights and by 4 for float32 weights, with close to no impact to the quality by operating on the outliers in half-precision. The host that this will be running on for now has 8 x H100 GPUs (80G VRAM a piece), and ideally I’d How to use Qwen2-VL on multiple gpus? Loading From the paper LLM. However, it is possible to place supported operations on an NVIDIA GPU, while leaving any unsupported ones on CPU.
