Tetra is a high-level parallel programming language that is designed to make parallel programs easier to write, visualize, debug, and optimize. Its goals are to make parallel programming easier for students and professionals programmers alike.

It combines a friendly, Python-like syntax, static typing, powerful data structures, and built-in parallelism. It comes with a graphical development environment.

Tetra is still a work in progress, but will combine the following components:

• A programming language geared towards making parallel programming as easy as possible. The syntax is based on Python, but it includes static typing with local type inference, and garbage collection.

• A development environment for writing Tetra programs including an integrated simulator. The simulator will provide advanced tools for visualizing and debugging programs including the ability to see code executing on multiple (virtual) cores simultaneously, pause cores, set the relative speed of cores, and the ability to save and replay execution traces. These abilities will aid the user in being able to discover and correct subtle bugs that would otherwise be non-deterministic and thus hard to find.

Tetra thus far only works on Linux systems. To install:

1 Download Tetra, either by cloning the repository, or by downloading a zip file.

2 Install dependencies

sudo apt-get install build-essential clang bison qt5-default

3 Compile Tetra:

cd tetra
./build

You should now be able to run the command line interpreter as bin/tetra or the IDE as bin/tetraide.
