Developer tools for HPC. Because we can’t have cloud but we want nice things too.

Tunel is named for what it does. “Tunel” is an elegant derivation of “tunnel” and will do exactly that - create a tunel between your local workstation and an HPC cluster. Tunel tries to abstract away some of the complexity of launching interfaces that feel a bit more modern. In its simplest form this means:

  1. Installing tunel locally and discovering what is available on your cluster

  2. Running a local server (or via the command line) selecting and configuring an application to run.

  3. Launching it via a ssh tunnel to your cluster resource

  4. Getting back an address to open up and start working.

The library contains a collection of apps that are ready to go, and you can also use one of our templates to create your own! Head over to see currently provided applications or to see the code, head over to the repository.

Getting started with Tunel

Tunel can be installed from pypi or directly from the repository. See Installation for installation, and then the Getting Started section for using the client.
