12# NOTE, this feature is experimental and may not work on all systems.
13# The trtllm-llmapi-launch is a script that launches the LLM-API code on
14# Slurm-like systems, and can support multi-node and multi-GPU setups.
15
16# Note that, the number of MPI processes should be the same as the model world
17# size. e.g. For tensor_parallel_size=16, you may use 2 nodes with 8 gpus for
18# each, or 4 nodes with 4 gpus for each or other combinations.
19
20# This docker image should have tensorrt_llm installed, or you need to install
21# it in the task.
22
23# The following variables are expected to be set in the environment:
24# You can set them via --export in the srun/sbatch command.
25# CONTAINER_IMAGE: the docker image to use, you'd better install tensorrt_llm in it, or install it in the task.
26# MOUNT_DIR: the directory to mount in the container
27# MOUNT_DEST: the destination directory in the container
28# WORKDIR: the working directory in the container
29# SOURCE_ROOT: the path to the TensorRT-LLM source
30# PROLOGUE: the prologue to run before the script
31# LOCAL_MODEL: the local model directory to use, NOTE: downloading from HF is
32# not supported in Slurm mode, you need to download the model and put it in
33# the LOCAL_MODEL directory.
