+# Instructions to Modify and Build ggml with OpenVINO
+
+## Step 1: Modify the Source Code
+
+In order to change the frontend `.so` path to the path to `.so` file, you need to add path to the `.so` file in cmake compiler option:
+1. Open a terminal and navigate to the root directory of this repo.
+2. Run the following commands to configure:
+   ```sh
+   mkdir build
+   cmake -B build -DGGML_OV_FRONTEND="${openvino_repo_dir}/bin/intel64/Release/libopenvino_ggml_frontend.so"
+   ```
+Where GGML_OV_FRONTEND should point to the path to `libopenvino_ggml_frontend.so` file.
+
+## Step 2: Build the Project
+
+After modifying the source code, you need to build the project using CMake. Follow these steps:
+
+1. (Optional) Enable debug option for ggml-openvino, this will output dump of subgraph sent to OpenVINO, information after convert ggml_cgraph to GraphIterator, and calculation input value/output value of each OP:
+   ```sh
+    cmake -B build -DGGML_OPENVINO_DEBUG=ON
+    ```
+
+2. Run the following commands to configure and build the project:
+   ```sh
+   cmake -B build -DGGML_OPENVINO=ON
+   cmake --build build -j
+   ```
+
+This will configure the project with OpenVINO support and build it using multiple cores for faster compilation.

Subject: [PATCH 038/166] 1. All operators implemented using OpenVINO can be
 successfully executed individually. 2. VIEW op output tensor shape is not
 same with CONT(non-contiguous) input tensor shape 3. CPY(non-contiguous)
 can't be implemented with original input/output tensor shape and data(need
 change the original shape when create input/output tensor)

Currently. VIEW op executed in the ggml backend and others executed in the OpenVINO Frontend.

Subject: [PATCH 042/166] 1. In the Prompt process and predict first token
 stage, the PERMUTE node needs to be integrated into the OV Frontend 2. In the
 predict latest token stage, the VIEW, CONT, Reshape need to be integrated
 into the OV Frontend.

+## OPENVINO
+
+### Build openvino-llama
+
+  ```bash
+  git lfs install --skip-smudge
+  git clone https://github.com/intel-sandbox/openvino-llama.git -b dev_ggml_frontend
+  cd openvino-llama
+  git submodule update --init --recursive
+
+  export OPENVINO_LLAMA_PATH=$(pwd)
+
+  cmake --preset Release
+  cmake --build build/Release
+  ```
+
+### Build llama.cpp-ov
+
+  ```bash
+  git clone https://github.com/intel-sandbox/llama.cpp-ov.git -b dev_backend_openvino
+  cd llama.cpp-ov
+
+  cmake --preset ReleaseOV
+  cmake --build build/ReleaseOV
+  ```
+
+Download the test model file [Phi-3-mini-4k-instruct-fp16.gguf](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-gguf) from hugging face website.
+  ``` bash
+  wget https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-gguf/resolve/main/Phi-3-mini-4k-instruct-fp16.gguf?download=true -O  ~/models/Phi-3-mini-4k-instruct-gguf/Phi-3-mini-4k-instruct-fp16.gguf
+  ```
+
+Execute the following command to test.
+  ```bash
+  export GGML_OPENVINO_CACHE_DIR=/tmp/ov_cache
+  # Currently GGML_OPENVINO_WEIGHT_AS_INPUT has better performance
+  export GGML_OPENVINO_WEIGHT_AS_INPUT=1
+  ./build/ReleaseOV/bin/llama-simple -m ~/models/Phi-3-mini-4k-instruct-gguf/Phi-3-mini-4k-instruct-fp16.gguf -n 10 "Hello, my name is "
+  ```
+
+Environment variables:
+- GGML_OPENVINO_WEIGHT_AS_INPUT:
+    Pass the weights as input to the OpenVINO model instead of creating Constant nodes for them.
+- GGML_OPENVINO_CACHE_DIR:
+    If set, model caching in OpenVINO will be used.
+- GGML_OPENVINO_DUMP_CGRAPH:
+    Dumped the compute graph to "cgraph.txt". Note that the the compute graph is different for every token, so the later cgraph will overwrite the previous one.
+- GGML_OPENVINO_PROFILING:
+    Print the time taken for each phase in the OpenVINO backend.
+- GGML_OPENVINO_DUMP_IR:
+    Dump the converted OpenVINO IR. The filenames are timestamps.
+- GGML_OPENVINO_DEBUG_INPUT
+- GGML_OPENVINO_DEBUG_OUTPUT
+
+To use Llama.cpp's builtin CPU backend:
+```bash
+cmake --preset ReleaseCPU
+cmake --build build/ReleaseCPU
+
+./build/ReleaseCPU/bin/llama-simple -m ~/models/Phi-3-mini-4k-instruct-gguf/Phi-3-mini-4k-instruct-fp16.gguf -n 10 "Hello, my name is "
+```
+
 ## Notes about GPU-accelerated backends
 
 The GPU may still be used to accelerate some parts of the computation even when using the `-ngl 0` option. You can fully disable GPU acceleration by using `--device none`.

-# Instructions to Modify and Build ggml with OpenVINO
-
-## Step 1: Modify the Source Code
-
-In order to change the frontend `.so` path to the path to `.so` file, you need to add path to the `.so` file in cmake compiler option:
-1. Open a terminal and navigate to the root directory of this repo.
-2. Run the following commands to configure:
-   ```sh
-   mkdir build
-   cmake -B build -DGGML_OV_FRONTEND="${openvino_repo_dir}/bin/intel64/Release/libopenvino_ggml_frontend.so"
-   ```
-Where GGML_OV_FRONTEND should point to the path to `libopenvino_ggml_frontend.so` file.
-
-## Step 2: Build the Project
-
-After modifying the source code, you need to build the project using CMake. Follow these steps:
-
-1. (Optional) Enable debug option for ggml-openvino, this will output dump of subgraph sent to OpenVINO, information after convert ggml_cgraph to GraphIterator, and calculation input value/output value of each OP:
-   ```sh
-    cmake -B build -DGGML_OPENVINO_DEBUG=ON
-    ```
-
-2. Run the following commands to configure and build the project:
-   ```sh
-   cmake -B build -DGGML_OPENVINO=ON
-   cmake --build build -j
-   ```
-
-This will configure the project with OpenVINO support and build it using multiple cores for faster compilation.

 ## OPENVINO
 
-### Build openvino
+[OpenVINO](https://docs.openvino.ai/2025/index.html) is a open-source toolkit for optimizing and deploying performant AI inference, specifically designed for Intel hardware including CPUs, GPUs, and NPUs in the cloud, on-prem, and on the edge alike. The OpenVINO backend enhances performance by leveraging hardware-specific optimizations and can be enabled for use with llama.cpp.
 
-```bash
-git clone https://github.com/openvinotoolkit/openvino.git
-cd openvino
-git submodule update --init --recursive
-export OPENVINO_DIR=$(pwd)
+Follow the instructions below to install OpenVINO runtime and build llama.cpp with OpenVINO support.
+
+### 1. Install OpenVINO Runtime
 
-sudo ./install_build_dependencies.sh
+- Follow the guide to install OpenVINO Runtime from an archive file: **[Install OpenVINO™ Runtime on Linux from an Archive File.](https://docs.openvino.ai/2025/get-started/install-openvino/install-openvino-archive-linux.html)**
 
-mkdir -p build/Release && cd build/Release
-cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_DEBUG_CAPS=ON ../..
+- After installation, make sure to [source the environment setup script](https://docs.openvino.ai/2025/get-started/install-openvino/install-openvino-archive-linux.html#step-2-configure-the-environment):
+```bash
+source /opt/intel/openvino_2025.1.0/setupvars.sh
 ```
+- Verify OpenVINO is initialized properly
+```bash
+echo $OpenVINO_DIR
+```
+
+### 2. Build llama.cpp with OpenVINO Backend
 
-### Build llama.cpp-ov
+Clone the OpenVINO-enabled llama.cpp fork and build it:
 
 ```bash
-git clone https://github.com/intel-sandbox/llama.cpp-ov.git
-cd llama.cpp-ov
+git clone https://github.com/ravi9/llama.cpp.git
+cd llama.cpp
 git switch dev_backend_openvino
 
+# Build with OpenVINO support
 cmake --preset ReleaseOV
-cmake --build build/ReleaseOV
+cmake --build build/ReleaseOV --parallel
+
 ```
 
-Download the test model file [Phi-3-mini-4k-instruct-fp16.gguf](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-gguf) from hugging face website.
-  ``` bash
-  wget https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-gguf/resolve/main/Phi-3-mini-4k-instruct-fp16.gguf?download=true -O  ~/models/Phi-3-mini-4k-instruct-gguf/Phi-3-mini-4k-instruct-fp16.gguf
-  ```
+### 3. Download Sample Model
+
+Download the Phi-3 mini model for testing:
+
+```bash
+# Create models directory
+mkdir -p ~/models/Phi-3-mini-4k-instruct-gguf
+
+# Download model file
+wget https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-gguf/resolve/main/Phi-3-mini-4k-instruct-fp16.gguf \
+     -O ~/models/Phi-3-mini-4k-instruct-gguf/Phi-3-mini-4k-instruct-fp16.gguf
+
+```
+
+### 4. Run inference with OpenVINO backend:
+
+When using the OpenVINO backend, the first inference token may have slightly higher latency due to on-the-fly conversion to the OpenVINO graph. Subsequent tokens and runs will be faster.
 
-Execute the following command to test.
 ```bash
 export GGML_OPENVINO_CACHE_DIR=/tmp/ov_cache
-./build/ReleaseOV/bin/llama-simple -m ~/models/Phi-3-mini-4k-instruct-gguf/Phi-3-mini-4k-instruct-fp16.gguf -n 10 "Hello, my name is "
-```
-
-Environment variables:
-- GGML_OPENVINO_WEIGHT_AS_INPUT:
-    Pass the weights as input to the OpenVINO model instead of creating Constant nodes for them.
-- GGML_OPENVINO_CACHE_DIR:
-    If set, model caching in OpenVINO will be used.
-- GGML_OPENVINO_DUMP_CGRAPH:
-    Dumped the compute graph to "cgraph.txt". Note that the the compute graph is different for every token, so the later cgraph will overwrite the previous one.
-- GGML_OPENVINO_PROFILING:
-    Print the time taken for each phase in the OpenVINO backend.
-- GGML_OPENVINO_DUMP_IR:
-    Dump the converted OpenVINO IR. The filenames are timestamps.
-- GGML_OPENVINO_DEBUG_INPUT
-- GGML_OPENVINO_DEBUG_OUTPUT
-
-To use Llama.cpp's builtin CPU backend:
+
+./build/ReleaseOV/bin/llama-simple \
+    -m ~/models/Phi-3-mini-4k-instruct-gguf/Phi-3-mini-4k-instruct-fp16.gguf \
+    -n 50 \
+    "Hello, my name is "
+
+```
+
+### Using Llama.cpp's Built-in CPU Backend (for Comparison)
+
+To compare performance with the deafult CPU backend:
+
 ```bash
+# Build CPU-only version
 cmake --preset ReleaseCPU
-cmake --build build/ReleaseCPU
+cmake --build build/ReleaseCPU --parallel
+
+# Run with Default CPU backend
+./build/ReleaseCPU/bin/llama-simple \
+    -m ~/models/Phi-3-mini-4k-instruct-gguf/Phi-3-mini-4k-instruct-fp16.gguf \
+    -n 50 \
+    "Hello, my name is "
+
+```
+
+### Configuration Options
+
+Control OpenVINO behavior using these environment variables:
+
+-   **`GGML_OPENVINO_CACHE_DIR`**: Directory for model caching (recommended: `/tmp/ov_cache`). If set, enables model caching in OpenVINO.
+-   **`GGML_OPENVINO_WEIGHT_AS_INPUT`**: Pass the weights as input to the OpenVINO model instead of creating Constant nodes for them.

 Follow the instructions below to install OpenVINO runtime and build llama.cpp with OpenVINO support.
 
+### Prerequisites
+
+- Linux or Windows system with Intel hardware (CPU, GPU, or NPU)
+- **For Intel GPU or NPU Usage**: Install the appropriate hardware drivers for your Intel GPU or NPU. For detailed instructions, see: [Additional Configurations for Hardware Acceleration](https://docs.openvino.ai/2025/get-started/install-openvino/configurations.html).
+- Git, CMake, and Ninja software tools are needed for building
+```bash
+  sudo apt-get update
+  sudo apt-get install -y build-essential libcurl4-openssl-dev libtbb12 cmake ninja-build python3-pip curl wget tar
+```

Subject: [PATCH 116/166] Fix after rebasing

- Layout of cache k and cache v are unified: [seq, n_head, head_size]
- Add CPY and FLASH_ATTN_EXT, flash attn is not used yet
- Skip test-backend-ops due to flash attn test crash
- Add mutex around graph conversion to avoid test-thread-safety fali in the future
- Update NPU config
- Update GPU config to disable SDPA opt to make phi-3 run

+### Docker build Llama.cpp with OpenVINO Backend
+You can build and run llama.cpp with OpenVINO backend using Docker.
+
+```bash
+# Build the base runtime image with compiled shared libraries and minimal dependencies.
+docker build -t llama-openvino:base -f .devops/openvino.Dockerfile .
+
+# Build the complete image with all binaries, Python tools, gguf-py library, and model conversion utilities.
+docker build --target=full -t llama-openvino:full -f .devops/openvino.Dockerfile .
+
+# Build a minimal CLI-only image containing just the llama-cli executable.
+docker build --target=light -t llama-openvino:light -f .devops/openvino.Dockerfile .
+
+# Builds a server-only image with llama-server executable, health check endpoint, and REST API support. 
+docker build --target=server -t llama-openvino:server -f .devops/openvino.Dockerfile .
+
+# If you are behind a proxy:
+docker build --build-arg http_proxy=$http_proxy --build-arg https_proxy=$https_proxy --target=light --t llama-openvino:light -f .devops/openvino.Dockerfile .
 ```
 
+Run llama.cpp with OpenVINO backend Docker container.
+Save sample models in `~/models` as [shown above](#3-download-sample-model). It will be mounted to the container in the examples below.
+
+```bash
+#  Run Docker container
+docker run --rm -it -v ~/models:/models llama-openvino:light --no-warmup -m /models/Llama-3.2-1B-Instruct.fp16.gguf
+
+# With Intel GPU access (iGPU or dGPU)

+``` 
+
+Run Llama.cpp Server with OpenVINO Backend
+```bash
+# Run the Server Docker container server
+docker run --rm -it -p 8080:8080 -v ~/models:/models llama-openvino:server --no-warmup -m /models/Llama-3.2-1B-Instruct.fp16.gguf

 ## Notes about GPU-accelerated backends
 
 The GPU may still be used to accelerate some parts of the computation even when using the `-ngl 0` option. You can fully disable GPU acceleration by using `--device none`.
