OpenFF QCArchive Dataset Submission

Dataset Lifecycle

All datasets submitted to QCArchive via this repository conform to the Dataset Lifecycle.

See STANDARDS.md for submission standards. Datasets must be submitted as pull requests.

User Quickstart

0. Ensure git-lfs is installed on your local machine: https://git-lfs.github.com/

1. To submit a new dataset, begin by cloning this repository:

   export GIT_LFS_SKIP_SMUDGE=1
   git clone git@github.com:openforcefield/qca-dataset-submission.git
   

   This will clone the repo, but avoid downloading existing LFS objects. If you wish to download all LFS objects, leave off the export GIT_LFS_SKIP_SMUDGE=1.

2. Once cloned, create and switch to a new branch from master, then create a new directory in qca-dataset-submission/submissions/:

   git checkout -b <dataset-branch>
   mkdir qca-dataset-submission/submissions/YYYY-MM-DD-OpenFF-<DESCRIPTIVE-DATASET-NAME>-v1.0
   

   You will add all submission artifacts to this directory.

3. Create and activate a new conda env with basic submission-preparation requirements with:

   conda env create -f qca-dataset-submission/devtools/prod-envs/qcarchive-user-submit.yaml
   conda activate qcarchive-user-submit
   

4. Choose a starting notebook and README based on the type of dataset you wish to submit:

   • OptimizationDataset

   Copy the notebook and README for the dataset you want into the directory you created.

   cp examples/<dataset-type>/* qca-dataset-submission/submissions/YYYY-MM-DD-OpenFF-<DESCRIPTIVE-DATASET-NAME>-v1.0
   

5. Start up a Jupyter notebook with your new notebook:

   jupyter notebook qca-dataset-submission/submissions/YYYY-MM-DD-OpenFF-<DESCRIPTIVE-DATASET-NAME>-v1.0/generate-dataset.ipynb
   

   Edit the contents with appropriate metadata information, read in your molecules using the cells appropriate for your input data, and make any other modifications as needed for your specific needs.

6. Copy generated metadata components into README. Write a reasonably-detailed high-level description of the submission at the top.

7. Commit the following files in the submission directory you made:

   • your input files; please compress them if possible with e.g. bzip2
   • generate-dataset.ipynb
   • dataset.pdf
   • dataset.smi
   • dataset.json.bz2

8. Push your branch to Github:

   git push origin <dataset-branch>
   

9. Make a new PR for the branch. Validation will run automatically on your dataset.json.* file, indicating any potential issues prior to submission. Ask for help if you see validation failures you do not understand. Ping a reviewer in the comments.

10. Once reviewed and approved, your submission will be merged and submitted to QCArchive! Computations specified by the submission will be performed on OpenFF-managed compute resources.

Creating a compute expansion

If you have already computed a dataset but want to re-compute it with a new QCSpec (e.g. new level of theory), you can do so using a compute expansion. This is faster than creating a new dataset, and explicitly links datasets with the same molecules and purpose. A compute expansion involves adding a file called compute.json to your original submission, which contains the dataset metadata (identical to the original dataset) and the new compute spec. This can be done manually, or programatically. The programatic description is provided below, with an example of the notebook and of the file.

1. Create a new branch as described above, and navigate to the submission directory of the dataset you want to expand.
2. Create a new jupyter notebook called generate-compute.ipynb example here.
3. In the notebook, either download the original dataset and remove the molecules and original QCSpec, or re-create the dataset with the same name as the original and skip the molecule addition step.

• See below for details about how changes to the dataset are propagated; note that the dataset name must be the same, and changes to any metadata except compute-tag and the QCSpec will be ignored when submitting the compute expansion.
• Please note that the default compute_tag is openff; if you need to use a different one, please add it explicitly to the dataset at this step, as the compute.json file overrides the compute tag added manually to the PR. If you do need to change the compute tag after submission, you can change it by updating the label on the PR and the change will take effect when the error cycling action runs next.

4. Add the new QCSpec to the dataset, and save the dataset to compute.json, example here.
5. Add the additional compute spec to the submission's README.md file.
6. Add the generate-compute.ipynb and compute.json files to the submission's QCSubmit Manifest entry in the README.md file.
7. Proof the submission and open a PR. Dataset validation will run automatically.
8. Once the dataset is validated, request a review, and once approved, your compute expansion will be submitted!

When the PR is merged, the following happens:

• CI checks for compute*.json*, so files can be called anything so long as they follow that pattern.

• This gets loaded into a QCSubmit dataset structure in CI (see lifecycle.py, SubmittableBase) and submitted to MolSSI with openff.qcsubmit.datasets.datasets._BaseDataset.submit()

• submit() checks if the dataset already exists using only the dataset type and name. Changes in descriptions, other metadata, etc. don't affect anything. New/different molecules will also be ignored if the dataset name already exists.

• submit() adds the specifications

• submit() submits with the compute_tag and priority within the new compute.json.

• Other info in the dataset, such as dataset_tags, are not incorporated into additional compute submissons and thus changing them will not affect the dataset.

The Lifecycle of a Dataset Submission

All Open Force Field datasets submitted to QCArchive undergo well-defined lifecycle.

Each labeled rectangle in the lifecycle represents a state. A submission PR changes state according to the arrows. Changes in state may be performed by automation or manually by a human when certain critera are met.

The lifecycle process is described below, with [bracketed] items indicating the agent of action, one of:

• [GHA]: Github Actions
• [Board]: Github Project Board
• [Human]: A maintainer of the qca-dataset-submission repository.

1. A PR is created against qca-dataset-submission by a submitter.

   • the template is filled out with informational sections according to the PR template
   • [GHA] validation operates on all dataset*.json files found in the PR; performs validation checks
     • comment made based on validation checks
     • reruns on each push

2. Add card for the PR to Dataset Tracking board.

   • [Human] add 'tracking' tag to PR
   • [GHA] lifecycle-backlog will add card to "Backlog" state for PR if not yet there.

3. When the submission is ready to be submitted to public QCArchive (validations pass, submitters and reviewers satisfied), PR is merged.

   • [Board] PR card will move to state "Queued for Submission" immediately.
   • [GHA] lifecycle-backlog will move PR card to state "Queued for Submission" if merged and in state "Backlog"
   • [GHA] lifecycle-submission will attempt to submit the dataset
     • if successful, will move card to state "Error Cycling"; add comment to PR
     • if failed, will keep card queued; add comment to PR; attempt again next execution
   • [Human] Submit worker jobs on a server to begin compute. If using Nautilus, carefully monitor utilization and scale down resources as jobs finish.

4. COMPLETE, INCOMPLETE, ERROR numbers reported for Optimizations, TorsionDrives

   • [GHA] lifecycle-error-cycle will collect the above statistics for state "Error Cycling" PRs
     • will restart all errored Optimizations and TorsionDrives
     • will move PR to state "Archived/Complete" if no ERROR, INCOMPLETE, all COMPLETE

5. PR will remain in state "Error Cycling" until moved to "Requires Scientific Review" or until all tasks COMPLETE

   • [Human] if errors appear persistent, move to state "Requires Scientific Review"
   • discussion should be had on PR for next version
   • [Human] once decided, state moved to "End of Life"
   • [Human] ensure all worker jobs have been shut down.

6. [GHA] lifecycle-end-of-life will add tag 'end-of-life' to dataset in QCArchive for PR in "End of Life"

7. [GHA] lifecycle-archived-complete will add tag 'archived-complete' to dataset in QCArchive for PR in "Archived/Complete"

Management Touchpoints

In addition to the states given above, there are additional touchpoints available for managing dataset submissions:

1. The tracking label is the "on/off" switch for automation via Github Actions. To disable all automation on a submission PR, remove this label. To enable automation, add the label.

2. Submission priority can be changed by adding one of the following labels:

   • priority-high: highest priority
   • priority-normal: normal priority
   • priority-low: lowest priority

3. Submission routing to QCFractal managers on different compute resources can be accomplished with compute tags. Add a label like compute-<tagname> to set the compute tag for all QCArchive tasks associated with a submisison. Be sure to coordinate with QCFractal manager admins to ensure your chosen compute tag is being served on the expected resources. This mechanism can also be used to "dead-letter" computations that are no longer desired by setting a compute tag that no manager will service.

4. The order of a submission PR in a Dataset Tracking column matters. Submissions higher in a column will be operated on first by all Github Action automation. For example, if you want to error cycle a submission before any others so it has a higher chance of being pulled by idle manager workers, place it at the top of the Error Cycling column.

Dude where's my Dataset?

Finding the source of a dataset in QCArchive can be difficult; here we offer a mapping between a dataset in QCArchive and the folder which contains its inputs including a quick overview of some metadata and the status of the dataset. Note that new datasets submitted using QCSubmit know where they were created and have a long_description_url in the metadata which points directly to their home folder in this repository.

Status

The status only refers to the default specification which is required for all of our datasets. Currently this is B3LYP-D3BJ/DZVP.

Key:

100% of all default spec jobs have been complete.

some of the jobs in the dataset contain errors which may prevent the jobs from finishing, this could be something like a linear torsiondrive.

the dataset is currently running and may have some incomplete jobs.

Basic Datasets

These are currently used to compute properties of a minimum energy conformation (Hessians, wavefunctions, etc.), usually derived from completed optimization datasets.
