Daniel Hiltgen 4a5c9b8035 Finish unwinding idempotent payload logic

The recent ROCm change partially removed idempotent
payloads, but the ggml-metal.metal file for mac was still
idempotent.  This finishes switching to always extract
the payloads, and now that idempotentcy is gone, the
version directory is no longer useful.

Ollama on Linux

Install

Install Ollama running this one-liner:

curl -fsSL https://ollama.com/install.sh | sh

AMD Radeon GPU support

While AMD has contributed the amdgpu driver upstream to the official linux kernel source, the version is older and may not support all ROCm features. We recommend you install the latest driver from https://www.amd.com/en/support/linux-drivers for best support of your Radeon GPU.

Manual install

Download the `ollama` binary

Ollama is distributed as a self-contained binary. Download it to a directory in your PATH:

sudo curl -L https://ollama.com/download/ollama-linux-amd64 -o /usr/bin/ollama
sudo chmod +x /usr/bin/ollama

Adding Ollama as a startup service (recommended)

Create a user for Ollama:

sudo useradd -r -s /bin/false -m -d /usr/share/ollama ollama

Create a service file in /etc/systemd/system/ollama.service:

[Unit]
Description=Ollama Service
After=network-online.target

[Service]
ExecStart=/usr/bin/ollama serve
User=ollama
Group=ollama
Restart=always
RestartSec=3

[Install]
WantedBy=default.target

Then start the service:

sudo systemctl daemon-reload
sudo systemctl enable ollama

Install CUDA drivers (optional – for Nvidia GPUs)

Download and install CUDA.

Verify that the drivers are installed by running the following command, which should print details about your GPU:

nvidia-smi

Install ROCm (optional - for Radeon GPUs)

Download and Install

Make sure to install ROCm v6

Start Ollama

Start Ollama using systemd:

sudo systemctl start ollama

Update

Update ollama by running the install script again:

curl -fsSL https://ollama.com/install.sh | sh

Or by downloading the ollama binary:

sudo curl -L https://ollama.com/download/ollama-linux-amd64 -o /usr/bin/ollama
sudo chmod +x /usr/bin/ollama

Viewing logs

To view logs of Ollama running as a startup service, run:

journalctl -u ollama

Uninstall

Remove the ollama service:

sudo systemctl stop ollama
sudo systemctl disable ollama
sudo rm /etc/systemd/system/ollama.service

Remove the ollama binary from your bin directory (either /usr/local/bin, /usr/bin, or /bin):

sudo rm $(which ollama)

Remove the downloaded models and Ollama service user and group:

sudo rm -r /usr/share/ollama
sudo userdel ollama
sudo groupdel ollama
