## Background
|
||||
|
||||
SYCL is a higher-level programming model to improve programming productivity on various hardware accelerators—such as CPUs, GPUs, and FPGAs. It is a single-source embedded domain-specific language based on pure C++17.
|
||||
**SYCL** is a high-level parallel programming model designed to improve developers productivity writing code across various hardware accelerators such as CPUs, GPUs, and FPGAs. It is a single-source language designed for heterogeneous computing and based on standard C++17.
|
||||
|
||||
oneAPI is a specification that is open and standards-based, supporting multiple architecture types including but not limited to GPU, CPU, and FPGA. The spec has both direct programming and API-based programming paradigms.
|
||||
**oneAPI** is an open ecosystem and a standard-based specification, supporting multiple architectures including but not limited to intel CPUs, GPUs and FPGAs. The key components of the oneAPI ecosystem include:
|
||||
|
||||
Intel uses the SYCL as direct programming language to support CPU, GPUs and FPGAs.
|
||||
- **DPCPP** *(Data Parallel C++)*: The primary oneAPI SYCL implementation, which includes the icpx/icx Compilers.
|
||||
- **oneAPI Libraries**: A set of highly optimized libraries targeting multiple domains *(e.g. oneMKL - Math Kernel Library)*.
|
||||
- **oneAPI LevelZero**: A high performance low level interface for fine-grained control over intel iGPUs and dGPUs.
|
||||
- **Nvidia & AMD Plugins**: These are plugins extending oneAPI's DPCPP support to SYCL on Nvidia and AMD GPU targets.
|
||||
|
||||
To avoid to re-invent the wheel, this code refer other code paths in llama.cpp (like OpenBLAS, cuBLAS, CLBlast). We use a open-source tool [SYCLomatic](https://github.com/oneapi-src/SYCLomatic) (Commercial release [Intel® DPC++ Compatibility Tool](https://www.intel.com/content/www/us/en/developer/tools/oneapi/dpc-compatibility-tool.html)) migrate to SYCL.
|
||||
### Llama.cpp + SYCL
|
||||
This SYCL "backend" follows the same design found in other llama.cpp BLAS-based paths such as *OpenBLAS, cuBLAS, CLBlast etc..*. The oneAPI's [SYCLomatic](https://github.com/oneapi-src/SYCLomatic) open-source migration tool (Commercial release [Intel® DPC++ Compatibility Tool](https://www.intel.com/content/www/us/en/developer/tools/oneapi/dpc-compatibility-tool.html)) was used for this purpose.
|
||||
|
||||
The llama.cpp for SYCL is used to support Intel GPUs.
|
||||
The llama.cpp SYCL backend supports:
|
||||
- Intel GPUs.
|
||||
- Nvidia GPUs.
|
||||
|
||||
For Intel CPU, recommend to use llama.cpp for X86 (Intel MKL building).
|
||||
*Upcoming support: AMD GPUs*.
|
||||
|
||||
When targetting **Intel CPUs**, it is recommended to use llama.cpp for [x86_64](README.md#intel-onemkl) approach.

*Notes:*
|
||||
|
||||
### Memory
|
||||
- Device memory can be a limitation when running a large model on an intel GPU. The loaded model size, *`llm_load_tensors: buffer_size`*, is displayed in the log when running `./bin/main`.
|
||||
|
||||
The memory is a limitation to run LLM on GPUs.
|
||||
- Please make sure the GPU shared memory from the host is large enough to account for the model's size. For e.g. the *llama-2-7b.Q4_0* requires at least 8.0GB for integrated GPUs and 4.0GB for discrete GPUs.
|
||||
|
||||
When run llama.cpp, there is print log to show the applied memory on GPU. You could know how much memory to be used in your case. Like `llm_load_tensors: buffer size = 3577.56 MiB`.
|
||||
- If the iGPU has less than 80 EUs *(Execution Unit)*, the inference speed will likely be too slow for practical use.
|
||||
|
||||
For iGPU, please make sure the shared memory from host memory is enough. For llama-2-7b.Q4_0, recommend the host memory is 8GB+.
|
||||
### Nvidia GPUs
|
||||
The BLAS acceleration on Nvidia GPUs through oneAPI can be obtained using the Nvidia plugins for oneAPI and the cuBLAS backend of the upstream oneMKL library. Details and instructions on how to setup the runtime and library can be found in [this section](#i-setup-environment)
|
||||
|
||||
For dGPU, please make sure the device memory is enough. For llama-2-7b.Q4_0, recommend the device memory is 4GB+.

### oneMKL for CUDA
|
||||
*Notes:*
|
||||
- Support for Nvidia targets through oneAPI is currently limited to Linux platforms.
|
||||
|
||||
The current oneMKL release does not contain the oneMKL cuBlas backend.
|
||||
As a result for Nvidia GPU's oneMKL must be built from source.
|
||||
- Please make sure the native oneAPI MKL *(dedicated to intel CPUs and GPUs)* is not "visible" at this stage to properly setup and use the built-from-source oneMKL with cuBLAS backend in llama.cpp for Nvidia GPUs.
|
||||
|
||||
```
|
||||
git clone https://github.com/oneapi-src/oneMKL
|
||||
cd oneMKL
|
||||
mkdir build
|
||||
cd build
|
||||
cmake -G Ninja .. -DCMAKE_CXX_COMPILER=icpx -DCMAKE_C_COMPILER=icx -DENABLE_MKLGPU_BACKEND=OFF -DENABLE_MKLCPU_BACKEND=OFF -DENABLE_CUBLAS_BACKEND=ON

|
||||
// Add paths as necessary
|
||||
```
|
||||
|
||||
## Docker
|
||||
|
||||
Note:
|
||||
- Only docker on Linux is tested. Docker on WSL may not work.
|
||||
- You may need to install Intel GPU driver on the host machine (See the [Linux](#linux) section to know how to do that)
|
||||
|
||||
### Build the image
|
||||
|
||||
You can choose between **F16** and **F32** build. F16 is faster for long-prompt inference.
|
||||
|
||||
|
||||
The docker build option is currently limited to *intel GPU* targets.
|
||||
### Build image
|
||||
```sh
|
||||
# For F16:
|
||||
#docker build -t llama-cpp-sycl --build-arg="LLAMA_SYCL_F16=ON" -f .devops/main-intel.Dockerfile .
|
||||
|
||||
# Or, for F32:
|
||||
docker build -t llama-cpp-sycl -f .devops/main-intel.Dockerfile .
|
||||
|
||||
# Note: you can also use the ".devops/server-intel.Dockerfile", which compiles the "server" example
|
||||
# Using FP16
|
||||
docker build -t llama-cpp-sycl --build-arg="LLAMA_SYCL_F16=ON" -f .devops/main-intel.Dockerfile .
|
||||
```
|
||||
|
||||
### Run
|
||||
*Notes*:
|
||||
|
||||
To build in default FP32 *(Slower than FP16 alternative)*, you can remove the `--build-arg="LLAMA_SYCL_F16=ON"` argument from the previous command.
|
||||
|
||||
You can also use the `.devops/server-intel.Dockerfile`, which builds the *"server"* alternative.
|
||||
|
||||
### Run container
|
||||
|
||||
```sh
|
||||
# Firstly, find all the DRI cards:
|
||||
# First, find all the DRI cards
|
||||
ls -la /dev/dri
|
||||
# Then, pick the card that you want to use.
|
||||
|
||||
# For example with "/dev/dri/card1"
|
||||
# Then, pick the card that you want to use (here for e.g. /dev/dri/card1).
|
||||
docker run -it --rm -v "$(pwd):/app:Z" --device /dev/dri/renderD128:/dev/dri/renderD128 --device /dev/dri/card1:/dev/dri/card1 llama-cpp-sycl -m "/app/models/YOUR_MODEL_FILE" -p "Building a website can be done in 10 simple steps:" -n 400 -e -ngl 33
|
||||
```
|
||||
|
||||
*Notes:*
|
||||
- Docker has been tested successfully on native Linux. WSL support has not been verified yet.
|
||||
- You may need to install Intel GPU driver on the **host** machine *(Please refer to the [Linux configuration](#linux) for details)*.
|
||||
|
||||
## Linux

||||
|
||||
### Setup Environment
|
||||
### I. Setup Environment
|
||||
|
||||
1. Install Intel GPU driver.
|
||||
1. **Install GPU drivers**
|
||||
|
||||
a. Please install Intel GPU driver by official guide: [Install GPU Drivers](https://dgpu-docs.intel.com/driver/installation.html).
|
||||
- **Intel GPU**
|
||||
|
||||
Note: for iGPU, please install the client GPU driver.
|
||||
Intel data center GPUs drivers installation guide and download page can be found here: [Get intel dGPU Drivers](https://dgpu-docs.intel.com/driver/installation.html#ubuntu-install-steps).
|
||||
|
||||
b. Add user to group: video, render.
|
||||
*Note*: for client GPUs *(iGPU & Arc A-Series)*, please refer to the [client iGPU driver installation](https://dgpu-docs.intel.com/driver/client/overview.html).
|
||||
|
||||
Once installed, add the user(s) to the `video` and `render` groups.
|
||||
|
||||
```sh
|
||||
sudo usermod -aG render username
|
||||
sudo usermod -aG video username
|
||||
sudo usermod -aG render $USER
|
||||
sudo usermod -aG video $USER
|
||||
```
|
||||
|
||||
Note: re-login to enable it.
|
||||
*Note*: logout/re-login for the changes to take effect.
|
||||
|
||||
c. Check
|
||||
Verify installation through `clinfo`:
|
||||
|
||||
```sh
|
||||
sudo apt install clinfo
|
||||
sudo clinfo -l
|
||||
```
|
||||
|
||||
Output (example):
|
||||
Sample output:

|
||||
`-- Device #0: Intel(R) Iris(R) Xe Graphics [0x9a49]
|
||||
```
|
||||
|
||||
2. Install Intel® oneAPI Base toolkit.
|
||||
- **Nvidia GPU**
|
||||
|
||||
a. Please follow the procedure in [Get the Intel® oneAPI Base Toolkit ](https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit.html).
|
||||
In order to target Nvidia GPUs through SYCL, please make sure the CUDA/CUBLAS native requirements *-found [here](README.md#cublas)-* are installed.
|
||||
Installation can be verified by running the following:
|
||||
```sh
|
||||
nvidia-smi
|
||||
```
|
||||
Please make sure at least one CUDA device is available, which can be displayed like this *(here an A100-40GB Nvidia GPU)*:
|
||||
```
|
||||
+---------------------------------------------------------------------------------------+
|
||||

|
||||
| | | Disabled |
|
||||
+-----------------------------------------+----------------------+----------------------+
|
||||
```
|
||||
|
||||
Recommend to install to default folder: **/opt/intel/oneapi**.
|
||||
|
||||
Following guide use the default folder as example. If you use other folder, please modify the following guide info with your folder.
|
||||
2. **Install Intel® oneAPI Base toolkit**
|
||||
|
||||
b. Check
|
||||
- **Base installation**
|
||||
|
||||
The base toolkit can be obtained from the official [Intel® oneAPI Base Toolkit](https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit.html) page.
|
||||
|
||||
Please follow the instructions for downloading and installing the Toolkit for Linux, and preferably keep the default installation values unchanged, notably the installation path *(`/opt/intel/oneapi` by default)*.
|
||||
|
||||
Following guidelines/code snippets assume the default installation values. Otherwise, please make sure the necessary changes are reflected where applicable.
|
||||
|
||||
Upon a successful installation, SYCL is enabled for the available intel devices, along with relevant libraries such as oneAPI MKL for intel GPUs.
|
||||
|
||||
- **Adding support to Nvidia GPUs**
|
||||
|
||||
**oneAPI**: In order to enable SYCL support on Nvidia GPUs, please install the [Codeplay oneAPI Plugin for Nvidia GPUs](https://developer.codeplay.com/products/oneapi/nvidia/download). User should also make sure the plugin version matches the installed base toolkit one *(previous step)* for a seamless "oneAPI on Nvidia GPU" setup.
|
||||
|
||||
|
||||
**oneMKL**: The current oneMKL releases *(shipped with the oneAPI base-toolkit)* do not contain the cuBLAS backend. A build from source of the upstream [oneMKL](https://github.com/oneapi-src/oneMKL) with the *cuBLAS* backend enabled is thus required to run it on Nvidia GPUs.
|
||||
|
||||
```sh
|
||||
source /opt/intel/oneapi/setvars.sh
|
||||
git clone https://github.com/oneapi-src/oneMKL
|
||||
cd oneMKL
|
||||
mkdir -p buildWithCublas && cd buildWithCublas
|
||||
cmake ../ -DCMAKE_CXX_COMPILER=icpx -DCMAKE_C_COMPILER=icx -DENABLE_MKLGPU_BACKEND=OFF -DENABLE_MKLCPU_BACKEND=OFF -DENABLE_CUBLAS_BACKEND=ON -DTARGET_DOMAINS=blas
|
||||
make
|
||||
```
|
||||
|
||||
|
||||
3. **Verify installation and environment**
|
||||
|
||||
In order to check the available SYCL devices on the machine, please use the `sycl-ls` command.
|
||||
```sh
|
||||
source /opt/intel/oneapi/setvars.sh
|
||||
sycl-ls
|
||||
```
|
||||
|
||||
There should be one or more level-zero devices. Please confirm that at least one GPU is present, like **[ext_oneapi_level_zero:gpu:0]**.
|
||||
- **Intel GPU**
|
||||
|
||||
When targeting an intel GPU, the user should expect one or more level-zero devices among the available SYCL devices. Please make sure that at least one GPU is present, for instance [`ext_oneapi_level_zero:gpu:0`] in the sample output below:
|
||||
|
||||
Output (example):
|
||||
```
|
||||

|
||||
|
||||
```
|
||||
|
||||
2. Build locally:
|
||||
- **Nvidia GPU**
|
||||
|
||||
Note:
|
||||
- You can choose between **F16** and **F32** build. F16 is faster for long-prompt inference.
|
||||
- By default, it will build for all binary files. It will take more time. To reduce the time, we recommend to build for **example/main** only.
|
||||
Similarly, user targetting Nvidia GPUs should expect at least one SYCL-CUDA device [`ext_oneapi_cuda:gpu`] as bellow:
|
||||
```
|
||||
[opencl:acc:0] Intel(R) FPGA Emulation Platform for OpenCL(TM), Intel(R) FPGA Emulation Device OpenCL 1.2 [2023.16.12.0.12_195853.xmain-hotfix]

|
||||
llama.cpp uses *mmap* as the default mode for reading the model file and copying it to the GPU. In some systems, `memcpy` might behave abnormally and therefore hang.
|
||||
|
||||
Solution: add **--no-mmap** or **--mmap 0**.
|
