Updates

  • OFF EP 5 submitted for consideration

    • https://github.com/openforcefield/standards/pull/30/files

    • An edit pass for typos has been done

      • JW – Thanks!

    • There’s been some discussion on the parent issue, looking at handling things in a more forward-looking/complete way.

      • JW – Thanks for pointing this out, I’ve tried to communicate alternatives

  • Constraint behavior with OpenMM

    • If all atoms are totally constrained, do NOT add the corresponding bond/angle force. Toolkit does this in a semi-hardcoded manner, Interchange is forced to duplicate this behavior

      • JW – On the surface, I’d think that we want to START ADDING the bond/angle physics parameters, even if they’re constrained.

      • (more discussion/explanation)

      • MT – I’ll have the new code path go toolkit → interchange with BOTH constraints AND bond physics, and just drop bond parameters by default in Interchange.to_openmm. I may have a kwarg to keep the bond physics parameters around.

      • MT – In the future, I’ll raise an issue/PR about whether we should keep both the constraint info AND bond physics parameters in Interchange.to_openmm. This issue/PR may be the initial implementation of the kwarg, or be about a change in default behavior.

  • MT - FYI – There’s an emerging discussion about evaluator on OpenCL

    • MT – Discussions I had with OM got pushed forward into Issue #424. Some question about whether Evaluator-OpenMM interface works with OpenCL.

    • JS opened

      not sure if I should review and/or approve?

      • JW – I’d recommend reading it over and commenting, but not approving. Do tag SB to give him right of first refusal to be approver

  • MT – When should I open Evaluator #413 for review? Who should be approver?

    • JW – (commented) Let’s keep it as WIP until the OFFTK 0.11.0 RC package is out.

Pair work

  • MT – What is the finish line w/ VU?

    • Serving as advisors is fun, but not a great use of our effort (logistic & cognitive)

    • JW – JBG’s defense (in a month that begins with M)

  • Bespokefit conda-forge release

    • JW – Update bespokefit recipe - Update from test env. DOWNPIN toolkit to avoid biopolymer release breaks, all deps in test env are required, none are actually optional!!

      • (MT updated staged-recipes PR )

      • MT will carry this forward to package build

  • https://github.com/openforcefield/openff-toolkit/pull/1195 NOT merged
