### GPU Selection

If you have multiple NVIDIA GPUs in your system and want to limit Ollama to use
a subset, you can set `CUDA_VISIBLE_DEVICES` to a comma separated list of GPUs.
Numeric IDs may be used, however ordering may vary, so UUIDs are more reliable.
You can discover the UUID of your GPUs by running `nvidia-smi -L` If you want to
ignore the GPUs and force CPU usage, use an invalid GPU ID (e.g., "-1")

### Linux Suspend Resume

On linux, after a suspend/resume cycle, sometimes Ollama will fail to discover
your NVIDIA GPU, and fallback to running on the CPU.  You can workaround this
driver bug by reloading the NVIDIA UVM driver with `sudo rmmod nvidia_uvm &&
sudo modprobe nvidia_uvm`

## AMD Radeon
Ollama supports the following AMD GPUs:

### Linux Support
| Family         | Cards and accelerators                                                                                                               |
| -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| AMD Radeon RX  | `7900 XTX` `7900 XT` `7900 GRE` `7800 XT` `7700 XT` `7600 XT` `7600` `6950 XT` `6900 XTX` `6900XT` `6800 XT` `6800` `Vega 64` `Vega 56`    |
| AMD Radeon PRO | `W7900` `W7800` `W7700` `W7600` `W7500` `W6900X` `W6800X Duo` `W6800X` `W6800` `V620` `V420` `V340` `V320` `Vega II Duo` `Vega II` `VII` `SSG` |
| AMD Instinct   | `MI300X` `MI300A` `MI300` `MI250X` `MI250` `MI210` `MI200` `MI100` `MI60` `MI50`                                                               |

### Windows Support
With ROCm v6.1, the following GPUs are supported on Windows.

| Family         | Cards and accelerators                                                                                                               |
| -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| AMD Radeon RX  | `7900 XTX` `7900 XT` `7900 GRE` `7800 XT` `7700 XT` `7600 XT` `7600` `6950 XT` `6900 XTX` `6900XT` `6800 XT` `6800`    |
| AMD Radeon PRO | `W7900` `W7800` `W7700` `W7600` `W7500` `W6900X` `W6800X Duo` `W6800X` `W6800` `V620` |


### Overrides on Linux
Ollama leverages the AMD ROCm library, which does not support all AMD GPUs. In
some cases you can force the system to try to use a similar LLVM target that is
close.  For example The Radeon RX 5400 is `gfx1034` (also known as 10.3.4)
however, ROCm does not currently support this target. The closest support is
`gfx1030`.  You can use the environment variable `HSA_OVERRIDE_GFX_VERSION` with
`x.y.z` syntax.  So for example, to force the system to run on the RX 5400, you
would set `HSA_OVERRIDE_GFX_VERSION="10.3.0"` as an environment variable for the
server.  If you have an unsupported AMD GPU you can experiment using the list of
supported types below.

If you have multiple GPUs with different GFX versions, append the numeric device
number to the environment variable to set them individually.  For example,
`HSA_OVERRIDE_GFX_VERSION_0=10.3.0` and  `HSA_OVERRIDE_GFX_VERSION_1=11.0.0`

At this time, the known supported GPU types on linux are the following LLVM Targets.
This table shows some example GPUs that map to these LLVM targets:
| **LLVM Target** | **An Example GPU** |
|-----------------|---------------------|
| gfx900 | Radeon RX Vega 56 |
| gfx906 | Radeon Instinct MI50 |
| gfx908 | Radeon Instinct MI100 |
| gfx90a | Radeon Instinct MI210 |
| gfx940 | Radeon Instinct MI300 |
| gfx941 | |
| gfx942 | |
| gfx1030 | Radeon PRO V620 |
| gfx1100 | Radeon PRO W7900 |
| gfx1101 | Radeon PRO W7700 |
| gfx1102 | Radeon RX 7600 |

AMD is working on enhancing ROCm v6 to broaden support for families of GPUs in a
future release which should increase support for more GPUs.

### GPU Selection

If you have multiple AMD GPUs in your system and want to limit Ollama to use a
subset, you can set `ROCR_VISIBLE_DEVICES` to a comma separated list of GPUs.
You can see the list of devices with `rocminfo`.  If you want to ignore the GPUs
and force CPU usage, use an invalid GPU ID (e.g., "-1").  When available, use the
`Uuid` to uniquely identify the device instead of numeric value.

### Container Permission

In some Linux distributions, SELinux can prevent containers from
accessing the AMD GPU devices.  On the host system you can run 
`sudo setsebool container_use_devices=1` to allow containers to use devices.

### Metal (Apple GPUs)
Ollama supports GPU acceleration on Apple devices via the Metal API.
