Re: [hpx-users] [VOTE] Proposal to split HPX into at least two smaller projects and repositories (Nanmiao Wu) ---------------------------------------------------------------------- Message: 1 Date: Wed, 16 Jun 2021 14:48:50 +0000 From: Nanmiao Wu <wnan...@lsu.edu> Subject: Re: [hpx-devel] [hpx-users] [VOTE] Proposal to split HPX into at least two smaller projects and repositories To: "hpx-us...@stellar-group.org" <hpx-us...@stellar-group.org> Cc: "hpx-devel@stellar-group.org" <hpx-devel@stellar-group.org> Message-ID: <bn7pr06mb6371dd5df9b807f989824d1ae9...@bn7pr06mb6371.namprd06.prod.outlook.com> Content-Type: text/plain; charset="windows-1252" - -1: ?no,? ?disagree?. I think splitting HPX to local and distributed ones would make developers more difficult to make things consistent.

I believe splitting the HPX to local and distributed cases will impact the test coverage, which is fundamentally important to a scalable software project. More importantly, HPX has good record on maintain similar APIs for local and distributed cases; with such split, it might be difficult to spot bugs, if any.

The goal for that software is probably to benefit all aspects of what HPX provides. HPX's idea of providing a stable semantic-C++ local and distributed parallel functionalities and having a successful history of achieving that are its essential features and what differentiates HPX from other not-so-successful projects.

This will exacerbate if they are maintained in separate repositories but is still a problem even if they are maintained in the same repository (e.g., HPX support for Vc, HPX examples repository, MiniGhost, HPXCL). That this interest exists is understandable because our excellent collaborators at the CSCS have had to invest significant time and resources to maintain the distributed functionalities of HPX, which, at least in the short term, has not been sufficiently rewarding. On the other hand, the problem will be the opposite if the distributed functionalities become the focus, which will not be ideal either.

This is a contentious topic, so before we do a large change like this we want to consult the community through a vote. My personal vote and motivation for the change will follow in a separate message. Practically speaking, the proposal is to move the on-node functionality of HPX (this includes futures, algorithms, basic CUDA/HIP support, a local-only runtime, and all the utilities required to support this) into a separate repository. The remaining distributed functionality of HPX would keep the hpx name, stay in the current repository, and it would gain one new dependency, called (e.g.) hpx-local. Releases of hpx and hpx-local would often be done together, but could be done independently of each other. The aim is to affect current users of distributed features of HPX as little as possible, while giving users of local-only features a project that, by default, gives them only local functionality. If there's consensus to go ahead with a split, we will also consider splitting HPX into more than two projects. Voting works as follows (from https://hpx.stellar-group.org/governance/<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fhpx.stellar-group.org%2Fgovernance%2F&data=04%7C01%7Cwnanmi1%40lsu.edu%7Ca2a00a2e9a024dc7c51308d930d366dd%7C2d4dad3f50ae47d983a09ae2b1f466f8%7C0%7C0%7C637594506829428151%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=HuZxqzfPL5Ty4ddSzM4dhQ85kGvzuap3QqFLJunvRdY%3D&reserved=0>): If a formal vote on a proposal is called (signaled simply by sending a email with [VOTE] in the subject line), all participants on the HPX user?s mailing list may express an opinion and vote. They do this by sending an email in reply to the original [VOTE] email, with the following vote and information: - +1: ?yes?, ?agree?: also willing to help bring about the proposed action - +0: ?yes?, ?agree?: not willing or able to help bring about the proposed action - -0: ?no?, ?disagree?: but will not oppose the action?s going forward - -1: ?no?, ?disagree?: opposes the action?s going forward and must propose an alternative action to address the issue (or a justification for not addressing the issue) This is a "Concensus approval" vote (see governance document for details). Responses from developers and users alike are encouraged. Please vote as soon as possible, but we will leave the voting open until Thursday 17th June.
