NVIDIA / TensorRT-LLM

TensorRT-LLM provides users with an easy-to-use Python API to define Large Language Models (LLMs) and build TensorRT engines that contain state-of-the-art optimizations to perform inference efficiently on NVIDIA GPUs. TensorRT-LLM also contains components to create Python and C++ runtimes that execute those TensorRT engines.

Finding protobuf files while benchmarking TensorRT-LLM #2101

Open KuntaiDu opened 3 months ago

KuntaiDu commented 3 months ago

System Info

I am working on the benchmarking suite in vLLM team, and now trying to run TensorRT-LLM for comparison. I am relying on this github repo (https://github.com/neuralmagic/tensorrt-demo) to serve the LLM, which contains several config.pbtxt files that specifies the batch size, max token length, etc and will be used for triton inference server. However, this repo is based on version r24.04 and I am not sure how to find the corresponding config.pbtxt files in version r24.07. Is there any references for me to locate these config.pbtxt files so that I can compare with TensorRT-LLM version r24.07?

Who can help?

Hi @KuntaiDu , please see the official location of the config.pbtxt file for v0.11 at here: https://github.com/triton-inference-server/tensorrtllm_backend/tree/v0.11.0/all_models/inflight_batcher_llm.

Before you launch the tritonserver, you'll need to set several parameters, please follow the documents of the TensorRT-LLM backend repo and feel free to let us know if there are any questions. Thanks.

Hello @KuntaiDu, for the ci benchmark, would it be possible to provide the ci script that you're using? I could find the regression page with results https://buildkite.com/vllm/performance-benchmark/builds/4068#_ but couldn't find the ci script. I can help fix that script. But basically, to get a good run with good settings in the ci script, could you:

  1. build the engine like so: trtllm-build --model_config <> --use_fused_mlp --gpt_attention_plugin bfloat16 --output_dir OUTPUT --max_batch_size 2048 --max_input_len 4096 --max_seq_len 6144 --reduce_fusion disable --workers 8 --max_num_tokens 16384
  2. set the triton runtime pbtxt files like so, with the base config.pbtx based on the v0.11 files that @kaiyux had mentioned
    • python3 /workspace/trt-llm_backend/tools/fill_template.py -i tensorrt_llm/config.pbtxt triton_backend:tensorrtllm,engine_dir:OUTPUT,decoupled_mode:true,batching_strategy:inflight_fused_batching,batch_scheduler_policy:guaranteed_no_evict,exclude_input_in_output:true,triton_max_batch_size:2048,max_queue_delay_microseconds:0,max_beam_width:1,max_queue_size:2048,enable_kv_cache_reuse:false
    • python3 /workspace/trt-llm_backend/tools/fill_template.py -i preprocessing/config.pbtxt triton_max_batch_size:2048,tokenizer_dir:model_name> ,preprocessing_instance_count:5
    • python3 /workspace/trt-llm_backend/tools/fill_template.py -i postprocessing/config.pbtxt triton_max_batch_size:2048,tokenizer_dir: ,postprocessing_instance_count:5,skip_special_tokens:false
    • python3 /workspace/trt-llm_backend/tools/fill_template.py -i ensemble/config.pbtxt triton_max_batch_size:2048
    • python3 /workspace/trt-llm_backend/tools/fill_template.py -i tensorrt_llm_bls/config.pbtxt triton_max_batch_size:2048,decoupled_mode:true,accumulate_tokens:"False",bls_instance_count:1
