-## Manual validations
-
-### E2E Performance Validation
-
-Before each release, we perform end-to-end performance validation to ensure no regressions are introduced. This validation uses the [vllm-benchmark workflow](https://github.com/pytorch/pytorch-integration-testing/actions/workflows/vllm-benchmark.yml) on PyTorch CI.
-
-**Current Coverage:**
-* Models: Llama3, Llama4, and Mixtral
-* Hardware: NVIDIA H100 and AMD MI300x
-* *Note: Coverage may change based on new model releases and hardware availability*
-
-**Performance Validation Process:**
-
-**Step 1: Get Access**
-Request write access to the [pytorch/pytorch-integration-testing](https://github.com/pytorch/pytorch-integration-testing) repository to run the benchmark workflow.
-
-**Step 2: Review Benchmark Setup**
-Familiarize yourself with the benchmark configurations:
-* [CUDA setup](https://github.com/pytorch/pytorch-integration-testing/tree/main/vllm-benchmarks/benchmarks/cuda)
-* [ROCm setup](https://github.com/pytorch/pytorch-integration-testing/tree/main/vllm-benchmarks/benchmarks/rocm)
-
-**Step 3: Run the Benchmark**
-Navigate to the [vllm-benchmark workflow](https://github.com/pytorch/pytorch-integration-testing/actions/workflows/vllm-benchmark.yml) and configure:
-* **vLLM branch**: Set to the release branch (e.g., `releases/v0.9.2`)
-* **vLLM commit**: Set to the RC commit hash
-
-**Step 4: Review Results**
-Once the workflow completes, benchmark results will be available on the [vLLM benchmark dashboard](https://hud.pytorch.org/benchmark/llms?repoName=vllm-project%2Fvllm) under the corresponding branch and commit.
-
-**Step 5: Performance Comparison**
-Compare the current results against the previous release to verify no performance regressions have occurred. Here is an
-example of [v0.9.1 vs v0.9.2](https://hud.pytorch.org/benchmark/llms?startTime=Thu%2C%2017%20Apr%202025%2021%3A43%3A50%20GMT&stopTime=Wed%2C%2016%20Jul%202025%2021%3A43%3A50%20GMT&granularity=week&lBranch=releases/v0.9.1&lCommit=b6553be1bc75f046b00046a4ad7576364d03c835&rBranch=releases/v0.9.2&rCommit=a5dd03c1ebc5e4f56f3c9d3dc0436e9c582c978f&repoName=vllm-project%2Fvllm&benchmarkName=&modelName=All%20Models&backendName=All%20Backends&modeName=All%20Modes&dtypeName=All%20DType&deviceName=All%20Devices&archName=All%20Platforms).

-server or finding the maximum throughput that it can handle, given some latency budget.
-
-Two ramp-up strategies are supported:
-- `linear`: Increases the request rate linearly from a start value to an end value.
-- `exponential`: Increases the request rate exponentially.
-
-The following arguments can be used to control the ramp-up:
-- `--ramp-up-strategy`: The ramp-up strategy to use (`linear` or `exponential`).
-- `--ramp-up-start-rps`: The request rate at the beginning of the benchmark.
-- `--ramp-up-end-rps`: The request rate at the end of the benchmark.

+
+# Pre-requisite:
+# 1. Checkout to your branch, install/ update the correct running env. For TPU, activate conda env and install the corresponding torch, xla version. 
+# 2. If the model is customized, replace the MODEL's config with the customized config.

+#   MODEL: the model served by vllm
+#   DOWNLOAD_DIR: directory to download and load model weights.
+#   INPUT_LEN: request input len
+#   OUTPUT_LEN: request output len

-# Automated vLLM Server Parameter Tuning
-
-This script automates the process of finding the optimal server parameter combination (`max-num-seqs` and `max-num-batched-tokens`) to maximize throughput for a vLLM server. It also supports additional constraints such as E2E latency and prefix cache hit rate.

-- [Configuration](#configuration)
-- [How to Run](#how-to-run)
-- [Example Use Cases](#example-use-cases)
-- [Output](#output)
-- [How It Works](#how-it-works)
-
-## Prerequisites
-
-Before running the script, please ensure the following steps are completed:
-
-1. **Clone vLLM & Set Up Branch**: Clone the vLLM repository and check out to your desired branch.
-
-```bash
-git clone https://github.com/vllm-project/vllm.git
-cd vllm
-# git checkout <your-branch>
-```
-
-1. **Install Environment**: Install or update the correct running environment. For TPU usage, activate your `conda` environment and install the corresponding `torch` and `torch_xla` versions.
-
-2. **Model Configuration**: If you are using a customized model, ensure its configuration files are correctly placed and accessible.
-
-## Configuration
-
-You must set the following variables at the top of the script before execution.
-
-| Variable | Description | Example Value |
-| --- | --- | --- |
-| `BASE` | **Required.** The absolute path to the parent directory of your vLLM repository directory. | `"$HOME"` |
-| `MODEL` | **Required.** The Hugging Face model identifier to be served by vllm. | `"meta-llama/Llama-3.1-8B-Instruct"` |
-| `SYSTEM`| **Required.** The hardware you are running on. Choices: `TPU` or `GPU`. (For other systems, it might not support saving profiles) | `"TPU"` |
-| `TP` | **Required.** The tensor-parallelism size. | `1` |
-| `DOWNLOAD_DIR` | **Required.** Directory to download and load model weights from. | `""` (default download path) |
-| `INPUT_LEN` | **Required.** Request input length. | `4000` |
-| `OUTPUT_LEN` | **Required.** Request output length. | `16` |
-| `MIN_CACHE_HIT_PCT` | Prefix cache hit rate in percentage (0-100). Set to `0` to disable. | `60` |
-| `MAX_LATENCY_ALLOWED_MS` | The maximum allowed P99 end-to-end latency in milliseconds. Set to a very large number (e.g., `100000000000`) to effectively ignore the latency constraint. | `500` |
-| `NUM_SEQS_LIST` | A space-separated string of `max-num-seqs` values to test. | `"128 256"` |
-| `NUM_BATCHED_TOKENS_LIST` | A space-separated string of `max-num-batched-tokens` values to test. | `"1024 2048 4096"` |
-
-**Note**: The default `NUM_SEQS_LIST` and `NUM_BATCHED_TOKENS_LIST` are set for medium-sized inputs/outputs. For very short contexts (e.g., 20 input, 20 output tokens), you may need to test larger values for `max-num-seqs`.
-
-## How to Run
-
-1. **Configure**: Edit the script and set the variables in the [Configuration](#configuration) section.
-2. **Execute**: Run the script. Since the process can take a long time, it is highly recommended to use a terminal multiplexer like `tmux` or `screen` to prevent the script from stopping if your connection is lost.
-
-```
-cd <FOLDER_OF_THIS_SCRIPT>
-bash auto_tune.sh
-```
-
-    Please note that the `bash auto_tune.sh` command cannot contain full or partial path with keyword `vllm`, otherwise `pkill -f vllm` command will also kill this script itself.
-
-## Example Use Cases
-
-Here are a few examples of how to configure the script for different goals:
-
-### 1. Maximize Throughput (No Latency Constraint)
-- **Goal**: Find the best `max-num-seqs` and `max-num-batched-tokens` to get the highest possible throughput for 1800 input tokens and 20 output tokens.
-- **Configuration**:
-
-```bash
-INPUT_LEN=1800
-OUTPUT_LEN=20
-MIN_CACHE_HIT_PCT=0
-MAX_LATENCY_ALLOWED_MS=100000000000 # A very large number
-```
-
-#### 2. Maximize Throughput with a Latency Requirement
-- **Goal**: Find the best server parameters when P99 end-to-end latency must be below 500ms.
-- **Configuration**:
-
-```bash
-INPUT_LEN=1800
-OUTPUT_LEN=20
-MIN_CACHE_HIT_PCT=0
-MAX_LATENCY_ALLOWED_MS=500
-```
-
-#### 3. Maximize Throughput with Prefix Caching and Latency Requirements
-- **Goal**: Find the best server parameters assuming a 60% prefix cache hit rate and a latency requirement of 500ms.
-- **Configuration**:
-
-```bash
-INPUT_LEN=1800
-OUTPUT_LEN=20
-MIN_CACHE_HIT_PCT=60
-MAX_LATENCY_ALLOWED_MS=500
-```
-
-## Output
-
-After the script finishes, you will find the results in a new, timestamped directory created inside `$BASE/auto-benchmark/`.
-
-- **Log Files**: The directory (`$BASE/auto-benchmark/YYYY_MM_DD_HH_MM/`) contains detailed logs for each run:
-    - `vllm_log_...txt`: The log output from the vLLM server for each parameter combination.
-    - `bm_log_...txt`: The log output from the `benchmark_serving.py` script for each benchmark run.
-
-- **Final Result Summary**: A file named `result.txt` is created in the log directory. It contains a summary of each tested combination and concludes with the overall best parameters found.

-
-  If it cannot find the best parameters, the final row will be `best_max_num_seqs: 0, best_num_batched_tokens: 0, best_throughput: 0`. This can be due to either the server not starting properly, or the latency requirement being too strict.
-
-- **Profiler Trace**: A directory named `profile` is created inside the log directory. It contains the profiler trace file (e.g., `.xplane.pb` for TPU or a `.json` trace for GPU) from the single best-performing run.
-
-## How It Works
-
-The script follows a systematic process to find the optimal parameters:
-
-1. **Find Max GPU Memory Utilization**: The script first determines the highest safe `gpu-memory-utilization` (starting from 0.98 and decreasing) that does not cause an Out-Of-Memory (OOM) error when launching the server. This ensures the benchmark runs use the maximum available memory without crashing.
-
-2. **Iterate and Benchmark**: It then enters a nested loop, iterating through every combination of `max-num-seqs` and `max-num-batched-tokens` provided in the configuration lists.
-
-3. **Latency-Aware Throughput Search**: For each parameter combination:
-    - The vLLM server is started.
-    - A benchmark is first run with an infinite request rate (`--request-rate inf`).
-    - If the resulting P99 E2E latency is within the `MAX_LATENCY_ALLOWED_MS` limit, this throughput is considered the maximum for this configuration.
-    - If the latency is too high, the script performs a search by iteratively decreasing the request rate until the latency constraint is met. This finds the highest sustainable throughput for the given parameters and latency requirement.
-
-4. **Track Best Result**: Throughout the process, the script tracks the parameter combination that has yielded the highest valid throughput so far.
-
-5. **Profile Collection**: For the best-performing run, the script saves the vLLM profiler output, which can be used for deep-dive performance analysis with tools like TensorBoard.
