[Arm Performance Libraries](https://developer.arm.com/downloads/-/arm-performance-libraries) provides developers with optimized math libraries for high-performance computing applications on Arm Neoverse-based hardware.

These libraries include highly-optimized functions for BLAS, LAPACK, FFT, sparse linear algebra, random number generation, libamath, and libastring.

Arm Performance Libraries are free to use and don’t require a license. These libraries are available for use on [Windows 11 on Arm](#windows), [macOS](#macos) (Apple Silicon), and [Linux](#linux) (AArch64) hosts.

## Install Arm Performance Libraries on Windows

msiexec.exe /i arm-performance-libraries_<version>_Windows.msi /quiet ACCEPT_EULA=1
```

To install Arm Performance Libraries using the `winget` package manager and automatically accept the End User License Agreement, run:

```
winget install --accept-package-agreements Arm.ArmPerformanceLibraries
```

You can now start linking your application to the Arm Performance libraries on your Windows on Arm device. Follow the examples in the included `RELEASE_NOTES` file of your extracted installation directory to get started.

For more information, see [Get started with Arm Performance Libraries](https://developer.arm.com/documentation/109361).

## Install Arm Performance Libraries on macOS

[Download](https://developer.arm.com/downloads/-/arm-performance-libraries) the appropriate package for your macOS distribution.

<div>
**Note**
</div>
The following commands use Arm Performance Libraries version 26.07. The same commands work with other versions. Replace the file used in these steps with the file for your version of choice. To find the latest version, see [Arm Performance Libraries downloads](https://developer.arm.com/downloads/-/arm-performance-libraries).

In a terminal, run the following command to download the macOS package:

```
wget https://developer.arm.com/-/cdn-downloads/permalink/Arm-Performance-Libraries/Version_26.07/arm-performance-libraries_26.07_macOS.tgz
```

Use tar to extract the file:

```
tar zxvf arm-performance-libraries_26.07_macOS.tgz
```

The output is similar to:

```
armpl_26.07_flang-22.dmg
```

Mount the disk image by running the following command from a terminal:

```
hdiutil attach armpl_26.07_flang-22.dmg
```

Now run the installation script as a superuser:

```
/Volumes/armpl_26.07_flang-22_installer/armpl_26.07_flang-22_install.sh -y
```

Using this command, you automatically accept the End User License Agreement and install packages to the `/opt/arm` directory. If you want to change the installation directory location, use the `--install_dir=` option with the script and provide the desired directory location.

To install Arm Performance Libraries using Homebrew in a terminal and automatically accept the End User License Agreement, run:

```
brew install arm-performance-libraries
```

The installer runs using `sudo`, so you may be asked to input your password.

To get started with Arm Performance Libraries on macOS, compile and test the examples in the `/opt/arm/<armpl_dir>/examples/` directory, or `<install_dir>/<armpl_dir>/examples/` if you installed to a different location.

For more information, see [Get started with Arm Performance Libraries](https://developer.arm.com/documentation/109362).

## Install Arm Performance Libraries on Linux

Arm Performance Libraries are supported on most Linux distributions such as Ubuntu, RHEL, SLES, and Amazon Linux on an `AArch64` host. The libraries are compatible with various versions of GCC, LLVM, and NVHPC. The GCC-compatible releases are built with GCC 14 and tested with GCC versions 7 to 15. The LLVM-compatible releases are tested with LLVM 22.1. The NVHPC-compatible releases are tested with NVHPC 26.3.

The following commands use Arm Performance Libraries version 26.07. The same commands work with other versions. Replace the file used in these steps with the file for your version of choice. To find the latest version, see [Arm Performance Libraries downloads](https://developer.arm.com/downloads/-/arm-performance-libraries).

In a terminal, run the following command to download the Debian package:

```
wget https://developer.arm.com/-/cdn-downloads/permalink/Arm-Performance-Libraries/Version_26.07/arm-performance-libraries_26.07_deb_gcc.tar
```

Use `tar` to extract the file and then change directory:

```
tar xf arm-performance-libraries_26.07_deb_gcc.tar
```

Run the installation script as a super user:

```
sudo ./arm-performance-libraries_26.07_deb/arm-performance-libraries_26.07_deb.sh --accept
```

Using the `--accept` switch, you automatically accept the End User License Agreement and the packages are installed to the `/opt/arm` directory.

If you want to change the installation directory location, use the `--install-to` option with the script and provide the desired directory location.

Arm has recently reviewed and strengthened our repository management processes. As a consequence we have revoked and replaced the Arm Toolchains repository signing key used up to July 2026. Current installations of Arm Performance Libraries continue to work although package manager update or upgrade operations may fail. Existing package users will need to install the latest arm-toolchains-repository package for their distribution as shown below. For more information see [the Arm Toolchains Repository installation guide](https://learn.arm.com/install-guides/arm-toolchains-repository).

Add the Arm Toolchains `apt` package repository to your system:

```
curl -O https://developer.arm.com/packages/arm-toolchains/ubuntu/pool/arm-toolchains-repository_2-2~noble_all.deb
sudo dpkg -i arm-toolchains-repository_2-2~noble_all.deb
sudo apt update
```

For more information about setting up the Arm Toolchains repository, see [Arm Toolchains](https://learn.arm.com/install-guides/arm-toolchains-repository/).

Download and install Arm Performance Libraries:

```
sudo apt install arm-performance-libraries
```

### Set up the environment for Arm Performance Libraries

Install environment modules on your Linux machine:

```
sudo apt install environment-modules
```

Set your bash environment to use the modules:

```
source /usr/share/modules/init/bash
```

Set the `MODULEPATH` environment variable to point to the location of the installed modulefiles for Arm Performance Libraries:

```
export MODULEPATH=$MODULEPATH:/opt/arm/modulefiles
```

List the available modules:

```
module avail
```

The output is similar to:

```
__output__ armpl/26.07_gcc
```

Load the appropriate module:

```
module load armpl/26.07_gcc
```

To get started with Arm Performance Libraries on Linux, compile and test the examples in the `/opt/arm/<armpl_dir>/examples/` directory, or `<install_dir>/<armpl_dir>/examples/` if you installed to a different location.
