Mondaic - Full Waveform Solutions

If your computer is equipped with one of the latest M-series chips (M1, M2, or M3) please follow the instructions given below to install Salvus.

Details on where to run Salvus: Where to Run Things?

The first step to install Salvus is to figure out where every component of it will run. The most common case is to have a full installation locally and additionally install a version of SalvusCompute on a larger workstation or cluster.

Rosetta is a translation layer for applications written for Intel chips that enables the M-series chip to run them as well. It is provided by Apple.

To install Rosetta, open a terminal and type:

Copy
/usr/sbin/softwareupdate --install-rosetta --agree-to-license

Navigate to your /Applications folder and right click on your preferred Terminal Application (The default Mac Terminal is located in /Applications/Utilities) then select Get Info. In the window that opens, select Open with Rosetta as shown in this picture:

Reopen the terminal.

If you want to keep your original Terminal running without Rosetta, consider using iTerm. Once installed, right-click on your iTerm application and select Duplicate. Now rename the duplicated iTerm application to something like iTerm (Rosetta). Now apply the procedure shown in the picture above to use Rosetta by default on this duplicated terminal and proceed with the following steps.

Details on the Python installation: Python Packages

Salvus depends on Python and a number of third party packages. We recommend to use the Miniconda distribution as package manager: Install Miniconda from here. Make sure to grab a version that is compatible with the M-series chips.

Unlike on other systems, we do not recommend using mamba on Apple M-series computers.

You can now choose between two supported versions of Python:

First, you need to download the list of python dependencies by running:

Copy
curl https://mondaic.com/environment-py39.yml -o environment.yml

Copy
curl https://mondaic.com/environment-py311.yml -o environment.yml

depending on your preference for Python version.

Next, please run the following commands to create a Salvus environment and install all dependencies. Make sure that you use a Terminal that was configured to use Rosetta as described above.

Copy
# Create a new environment with all required dependencies.
CONDA_SUBDIR=osx-64 conda env create -n salvus -f environment.yml
# Activate that environment.
conda activate salvus

Python 3.7 has reached end of life (EOL) in June 2023, and we only keep supporting a legacy environment with fixed version numbers. See here for details on how to set it up.

Details on the Mondaic Downloader: Mondaic Downloader
