Description of the bug | 错误描述

I was running mineru on GCP P4 server with 8gb vram but response time were not adequate for our use case.
Then I tried running it on GCP server with 2xP4 GPU.
Model is being loaded on only 1 GPU and there was no significant improvement in response time

We do not support running the same task on multiple GPUs to achieve a speedup. However, if you have multiple documents to process, you can distribute different tasks to different GPUs to achieve speedup through parallel processing of multiple tasks.
