GPU deployment using Vulkanlink
IREE can accelerate model execution on GPUs via Vulkan, a low-overhead graphics and compute API. Vulkan is cross-platform: it is available on many operating systems, including Android, Linux, and Windows. Vulkan is also cross-vendor: it is supported by most GPU vendors, including AMD, ARM, Intel, NVIDIA, and Qualcomm.
Support matrixlink
As IREE and the compiler ecosystem it operates within matures, more target specific optimizations will be implemented. At this stage, expect reasonable performance across all GPUs and for improvements to be made over time for specific vendors and architectures.
GPU Vendor | Category | Performance | Focus Architecture |
---|---|---|---|
ARM Mali GPU | Mobile | Good | Valhall+ |
Qualcomm Adreno GPU | Mobile | Reasonable | 640+ |
AMD GPU | Desktop/server | Good | RDNA+ |
NVIDIA GPU | Desktop/server | Reasonable | Turing+ |
Prerequisiteslink
In order to use Vulkan to drive the GPU, you need to have a functional Vulkan environment. IREE requires Vulkan 1.1 on Android and 1.2 elsewhere. It can be verified by the following steps:
Android mandates Vulkan 1.1 support since Android 10. You just need to make sure the device's Android version is 10 or higher.
Run the following command in a shell:
vulkaninfo | grep apiVersion
If vulkaninfo
does not exist, you will need to install the latest Vulkan
SDK. Installing via LunarG's package
repository is recommended, as it places Vulkan libraries and tools under
system paths so it's easy to discover.
If the listed version is lower than Vulkan 1.2, you will need to update the driver for your GPU.
Run the following command in a shell:
vulkaninfo | grep apiVersion

Get the IREE compilerlink
Vulkan expects the program running on GPU to be expressed by the SPIR-V binary exchange format, which the model must be compiled into.
Download the compiler from a releaselink
Python packages are regularly published to
PyPI. See the
Python Bindings page for more details.
The core iree-base-compiler
package includes the SPIR-V compiler:
Stable release packages are published to PyPI.
python -m pip install iree-base-compiler
Nightly pre-releases are published on GitHub releases.
python -m pip install \
--find-links https://iree.dev/pip-release-links.html \
--upgrade --pre iree-base-compiler
Tip
iree-compile
and other tools are installed to your python module
installation path. If you pip install with the user mode, it is under
${HOME}/.local/bin
, or %APPDATA%Python
on Windows. You may want to
include the path in your system's PATH
environment variable:
export PATH=${HOME}/.local/bin:${PATH}
Build the compiler from sourcelink
Please make sure you have followed the Getting started page to build IREE for your host platform and the Android cross-compilation page if you are cross compiling for Android. The SPIR-V compiler backend is compiled in by default on all platforms.
Ensure that the IREE_TARGET_BACKEND_VULKAN_SPIRV
CMake option is ON
when
configuring for the host.
Tip
iree-compile
will be built under the iree-build/tools/
directory. You
may want to include this path in your system's PATH
environment variable.
Get the IREE runtimelink
Next you will need to get an IREE runtime that supports the Vulkan HAL driver.
You can check for Vulkan support by looking for a matching driver and device:
$ iree-run-module --list_drivers
cuda: NVIDIA CUDA HAL driver (via dylib)
hip: HIP HAL driver (via dylib)
local-sync: Local execution using a lightweight inline synchronous queue
local-task: Local execution using the IREE multithreading task system
vulkan: Vulkan 1.x (dynamic)
$ iree-run-module --list_devices
cuda://GPU-00000000-1111-2222-3333-444444444444
local-sync://
local-task://
vulkan://00000000-1111-2222-3333-444444444444
Download the runtime from a releaselink

PyPI. See the
Python Bindings page for more details.
The core iree-base-runtime
package includes the Vulkan HAL drivers:
Stable release packages are published to PyPI.
python -m pip install iree-base-runtime
Nightly pre-releases are published on GitHub releases.
python -m pip install \

--upgrade --pre iree-base-runtime
Build the runtime from sourcelink
Please make sure you have followed the Getting started page to build IREE for Linux/Windows and the Android cross-compilation page for Android. The Vulkan HAL driver is compiled in by default on non-Apple platforms.
Ensure that the IREE_HAL_DRIVER_VULKAN
CMake option is ON
when configuring
for the target.
Compile and run a programlink
With the SPIR-V compiler and Vulkan runtime, we can now compile programs and run them on GPUs.
Compile a programlink
The IREE compiler transforms a model into its final deployable format in many sequential steps. A model authored with Python in an ML framework should use the corresponding framework's import tool to convert into a format (i.e., MLIR) expected by the IREE compiler first.
Using MobileNet v2 as an example, you can download the SavedModel with trained
weights from
TensorFlow Hub
and convert it using IREE's
TensorFlow importer. Then run the following
command to compile with the vulkan-spirv
target:
iree-compile \
--iree-hal-target-backends=vulkan-spirv \
--iree-vulkan-target=<...> \
mobilenet_iree_input.mlir -o mobilenet_vulkan.vmfb
iree-vulkan-target
specifies the GPU architecture to target. It accepts a few
schemes:
- LLVM CodeGen backend style: this is using LLVM AMDGPU/NVPTX CodeGen targets
like
gfx1100
for AMD RX 7900XTX andsm_86
for NVIDIA RTX 3090 GPUs. - Architecture code name style: e.g., using
rdna3
/valhall4
/ampere
/adreno
for AMD/ARM/NVIDIA/Qualcomm GPUs. - Product name style(1): e.g., using
rx7900xtx
/a100
for corresponding GPUs.
Here are a few examples showing how you can target various recent common GPUs:
GPU | Target Architecture | Architecture Code Name | Product Name |
---|---|---|---|
AMD RX7900XTX | gfx1100 |
rdna3 |
rx7900xtx |
AMD RX7900XT | gfx1100 |
rdna3 |
rx7900xt |
AMD RX7800XT | gfx1101 |
rdna3 |
rx7800xt |
AMD RX7700XT | gfx1101 |
rdna3 |
rx7700xt |
AMD RX6000 series | rdna2 |
||
AMD RX5000 series | rdna1 |
||
ARM Mali G715 | valhall4 |
e.g., mali-g715 |
|
ARM Mali G510 | valhall3 |
e.g., mali-g510 |
|
ARM GPUs | valhall |
||
NVIDIA RTX40 series | sm_89 |
ada |
e.g., rtx4090 |
NVIDIA RTX30 series | sm_86 |
ampere |
e.g., rtx3080ti |
NVIDIA RTX20 series | sm_75 |
turing |
e.g., rtx2070super |
Qualcomm GPUs | adreno |
If no target is specified, then a safe but more limited default will be used.
Note
Note that We don't support the full spectrum of GPUs here(2). This is more of a mechanism to help us develop IREE itself--in the long term we want to perform multiple targetting to generate to multiple architectures if no target is given.
- Note that we only support very limited GPUs that we are actively developing against in this category, particularly for desktops.
- It's also impossible to capture all details of a Vulkan implementation with a target triple, given the allowed variances on extensions, properties, limits, etc. So the target triple is just an approximation for usage.
Run a compiled programlink
In the build directory, run the following command:
tools/iree-run-module \
--device=vulkan \
--module=mobilenet_vulkan.vmfb \
--function=predict \
--input="1x224x224x3xf32=0"
The above assumes the exported function in the model is named as predict
and
it expects one 224x224 RGB image. We are feeding in an image with all 0 values
here for brevity, see iree-run-module --help
for the format to specify
concrete values.
