Issue

I was using a software and the root version provided to LHCb users with lb-conda default and when i try to do

fitTo( ... Parallelization( 4)) it throws
logic_error: Parallel minimization requested, but ROOT was not compiled with multiprocessing enabled, please recompile with -Droofit_multiprocess=ON for parallel evaluation
Can this be activated by default so when users get the default env got the root with multiprocess roofit?

[fedebetti]

Any news on this? I have the same problem

[matthewfeickert]

@conda-forge/root is there any reasons why this shouldn't be enabled in the default root_base output?

[guitargeek]

@fedebetti, @qgl90, have you checked that your fits benefit from the experimental multiprocessing backend with other ROOT builds outside Conda before? This parallelization was designed by ATLAS colleagues for their usecases, and so far other experiments have not validated yet that it also works for them. Maybe it would be good to do this first, before adding this to feature to the Conda build? Because it comes with some maintenance burden: roofit_multiprocess requires the draft API of the ZeroMQ library.

[qgl90]

Hi, I am not sure to understand here the issue to enable this by default. Regardless of Atlas having developed this for their use case, isn't switching off multiprocess when fitting gonna anyway give the same result as having this build flag off?
Ultimately the option will be verified by analyses and enabled if it gets the fits running faster. E.g. I don't get why a nice feature to achieve possible large speedups should be not available by default while keeping the default behaviour of roofit not exploiting it. Am I misunderstanding something?

[vepadulano]

Hi,

After reviewing #292 (thanks @matthewfeickert for the effort!) I have noticed the ZeroMQ feedstock does not build with the DRAFTS API, which is required to enable roofit_multiprocess. I have inquiried about the reason for disabling the DRAFTS API on the ZeroMQ feedstock at conda-forge/zeromq-feedstock#79 . Given the answer of the maintainer, it looks like there is currently no short-term plan to enable the API on their side, and doing so would require effort investment. My understanding is thus that if roofit_multiprocess depends on this, it can only be enabled with a custom build of ZeroMQ, making the conda distribution currently unsuitable unless the ZeroMQ teams is able to put in the effort in a short timespan. @guitargeek any further thoughts?

[matthewfeickert]

libzmq's Draft APIs are unstable by definition (if they become stable, they are promoted out of Draft status), so supporting drafts also changes the ABI of libzmq and breaks guarantees about linking stability.

We could add a drafts build of libzmq deprioritized by a feature, so it's still not installed by default, but available to packages that want to use it. I'll need to check if that would break existing packages that link libzmq or not, which would make adding the drafts build without breaking anything complicated.

— from conda-forge/zeromq-feedstock#79 (comment).

That doesn't sound like "game over" to me, but yeah, probably more a signal that a discussion should be had with the https://github.com/zeromq/libzmq maintainers on what the plans are for the drafts API.

[minrk]

adding some context, I am looking at building a drafts variant on libzmq and running some tests. It looks like it doesn't break the ABI of the stable API, so other packages built without drafts will run with drafts installed. So that means:

• down-prioritize drafts variant so it's opt-in to use it
• pin run_exports upper bound to x.y.z instead of x.y to reflect lack of ABI guarantee (little consequence since zeromq releases so rarely)

I think it should be okay.

zeromq really does need to take promoting out of drafts seriously, because I think no API has ever graduated from draft status, and most of those APIs really are quite stable by now, but there's no way to tell which except by promoting them out of draft.

[guitargeek]

@guitargeek any further thoughts?

No, I fully support everything that was said here! Drafts in zermq are indeed quite stable. Other packagers also include them. Most notably Fedora, where the enable the drafts even explicitly:
https://src.fedoraproject.org/rpms/zeromq/blob/f43/f/zeromq.spec#_71

Arch Linux also doesn't disable them:
https://gitlab.archlinux.org/archlinux/packaging/packages/zeromq/-/blob/main/PKGBUILD?ref_type=heads

[minrk]

There is actually this PR: zeromq/libzmq#4813 just last week that would mark the ppoll api (the only one relied on here, I think) as stable, no longer needing drafts.

[matthewfeickert]

@qgl90 This is now enabled (in PR #292) for root_base v6.36.04 build 4 and onwards. So you should now be able to do (with Pixi)

pixi init example && cd example
pixi config set --local run-post-link-scripts insecure  # only (optionally) needed given ROOT
pixi add root_base curl
pixi run curl -sLO https://raw.githubusercontent.com/conda-forge/root-feedstock/refs/heads/main/recipe/test_roofit_multiprocess.py
pixi run python ./test_roofit_multiprocess.py

and get stdout like
