本文主要是介绍编译运行 llama.cpp (vulkan, Intel GPU SYCL)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
llama.cpp 是一个运行 AI (神经网络) 语言大模型的推理程序, 支持多种 后端 (backend), 也就是不同的具体的运行方式, 比如 CPU 运行, GPU 运行等.
但是编译运行 llama.cpp 并不是那么容易的, 特别是对于 SYCL 后端 (用于 Intel GPU), 坑那是一大堆. 只有特定版本的 llama.cpp, 特定版本的 Linux 系统和 GPU 驱动程序, 才可能成功运行, 否则都是失败. 能够运行的版本还不是最新版本, 经过了大量尝试和失败, 才获得了本文的结果. 本文适用于 Intel GPU (A770) 和 Linux 操作系统.

2 编译 llama.cpp
为了方便, 窝们使用容器 (podman) 来进行编译. 首先构建基础镜像, Dockerfile 如下:
# ubuntu-intel-base (ubuntu 22.04)
FROM quay.io/jitesoft/ubuntu:22.04#RUN apt update && apt install -y ca-certificates
# 修复网络错误
RUN touch /etc/apt/apt.conf.d/99-verify-peer.conf && echo >>/etc/apt/apt.conf.d/99-verify-peer.conf "Acquire { https::Verify-Peer false }"# 设置 apt 镜像 (加速软件包下载)
RUN sed -i 's/http:\/\/archive.ubuntu.com/https:\/\/mirror.sjtu.edu.cn/g' /etc/apt/sources.list
# 更新系统, 安装软件包, 清理
RUN apt update && apt upgrade -y && apt install -y ca-certificates curl gpg cmake git && apt clean# 添加 intel apt 仓库

RUN echo "deb [arch=amd64,i386 signed-by=/usr/share/keyrings/intel-graphics.gpg] https://repositories.intel.com/gpu/ubuntu jammy client" > /etc/apt/sources.list.d/intel-gpu-jammy.list
RUN apt update# 安装 GPU 驱动
RUN apt install -y clinfo hwinfo intel-opencl-icd intel-level-zero-gpu level-zero intel-level-zero-gpu-raytracing mesa-vulkan-drivers intel-igc-cm level-zero-dev && apt clean

执行命令:
podman build -t ubuntu-intel-base .
结果:

2.1 编译 vulkan 后端
Dockerfile 如下:
# llama.cpp vulkan

RUN curl https://packages.lunarg.com/lunarg-signing-key-pub.asc | apt-key add -
RUN curl -o /etc/apt/sources.list.d/lunarg-vulkan-jammy.list https://packages.lunarg.com/vulkan/lunarg-vulkan-jammy.list
RUN apt update && apt-get install -y vulkan-sdk && apt cleanWORKDIR /app
COPY llama.cpp-b3600 .RUN cmake -B build -DGGML_VULKAN=1 -DBUILD_SHARED_LIBS=OFF && \cmake --build build --config Release --target llama-cli# 阶段 2
FROM ubuntu-intel-base as runtimeCOPY --from=build /app/build/bin/llama-cli /usr/bin/llama-cliCMD /bin/bash

结果:

3 运行测试
由于 Intel SYCL 只能在特定系统的特定驱动版本才能正常运行, 所以使用了虚拟机 GPU 透传 (详见文章 《QEMU/KVM 虚拟机显卡透传 (vfio-pci)》).
在这篇文章的虚拟机的基础上, 需要额外安装软件包:
sudo apt -y install gawk dkms linux-headers-$(uname -r) libc6-dev
sudo apt install -y intel-i915-dkms
重启虚拟机. 虚拟机内的相关信息如下:

4 总结与展望
本文使用容器 (podman) 编译了 llama.cpp 的 vulkan 后端和 SYCL 后端, 并成功在 Intel GPU (A770) 运行, 获得了较快的语言模型推理速度.
SYCL 后端比 vulkan 后端稍微快一点, 但不多. 使用的模型 (gguf), 生成长度, 软件驱动版本, 运行参数设置等很多因素, 都可能影响模型推理的速度, 所以本文中的运行速度仅供参考.
SYCL 比 vulkan 快不了多少, 但是使用 SYCL (Intel oneAPI) 却非常麻烦 !! 所以, 至少目前为止, 对于 A770 (16GB) 显卡来说, 使用 vulkan 即可, 强行使用 SYCL 的意义不大.
Intel 和 llama.cpp 对于 SYCL 还需要继续努力, 希望能够更方便, 更快速的运行大模型.
