TESS Atlas Catalog Pipeline

Coverage Status

NOTE: this is not meant to be a library (just a convenient place to keep the pipeline code)

Example Usage:

On Nectar

cd /mnt/storage/tess_atlas_pipeline/manager          
python pipeline.py tess_oct2_23 /mnt/storage/tess_atlas_webbuilder/source/objects/ --web-build-dir /mnt/storage/tess_atlas_webbuilder/ |& tee pipeline.log

This will (1) generate+submit slurm jobs on OzStar, (2) build the website once the slurm jobs are all completed.

Installation instructions

Clone this repo in the cloud-server where you want 'manage' the pipeline, and build the website.

Then, "install" the worker by copying the worker skeleton directory to the remote cluster (like OzStar), e.g.

scp -r worker <destination>:<worker_install_path>

For security, we want to do everything via restricted ssh keys.

Go to manager/ssh/ and run the setup-ssh script:

cd manager/ssh/
setup-ssh <username_on_remote> <worker_install_path>

This script will:

  • Generate two new ssh keys. One as the main key for running commands on the remote, and the other for rsync use
  • Print the lines you need to add to your ~/.ssh/authorized_keys on the remote cluster
  • Create an SSH configuration file to be used by the manager

Restricted rsync

rrsync you can get from the rsync github page. You should probably download the version that matches the rsync version on your remote machine. Check this by doing rsync --version.

If you have, for example, version 3.2.3, then do

cd <worker_install_path>/bin
wget https://raw.githubusercontent.com/WayneD/rsync/v3.2.3/support/rrsync

chmod +x rrsync

There's also a helper script in the skeleton dir that you can run.

Note, that depending on the version, the script may be a Perl or Python3 script. Check the shebang at the top of the file to make sure.
