Cross-posting on multiple sites is discouraged: Is cross-posting a question on multiple Stack Exchange sites permitted if the question is on-topic for each site?

How we should deal with questions that are appropriate for several sites, has been asked: How should we deal with questions that fit on more than one Stack Exchange site?, and one of the highest voted answers says (in 2017):

"there is a serious problem here that needs to be addressed. And the best answer I have here is we don't know yet." (Words in bold as exactly as in the original answer, not added by me)

People have come to Meta to ask about where specific types of questions should go, and this has been very well received:

Where should Developer Computer Setup Questions go?
Where should questions about MathJaX go?

Since there is no HPC stack exchange, and an Area51 proposal for it is likely to fail (has it been tried already?), where should questions about schedulers go?

Here is the result of searching "slurm" on various networks:
https://stackoverflow.com/search?q=slurm (1549 questions on SO)
https://superuser.com/search?q=slurm (40 questions on SU)
https://scicomp.stackexchange.com/search?q=slurm (8 questions on SciComp)
https://serverfault.com/search?q=slurm (82 questions on ServerFault)
https://unix.stackexchange.com/search?q=slurm (96 questions on Unix/Linux)

SO has the most questions, but it also has more users than any other site, and has 6.6k questions/day, compared to fewer than 200 questions/day for the rest. Since the use of schedulers is not "programming" one could argue that such questions are actually off-topic on SO.

SciComp might have the highest proportionality of HPC questions compared to the other networks, but since only 8 questions about SLURM have ever been asked on SciComp, it's unlikely to find an answer quickly there.

It's peculiar that the network that houses the most SLURM questions apart from SO, is UNIX/Linux, even though it really has nothing to do with UNIX or Linux because SLURM can easily be used on Windows or Mac as well.

For future users facing this conundrum, where should questions about schedulers go?

    Does this help you find it? – Sonic the Bracketed Hedgehog May 5 at 2:39
  • Is the question about design, formal analysis, implementation, or (selection and configuration) of the scheduler? I thought we did have a HPC sister site... Ah yeah, you've already mentioned scicomp.stackexchange.com which has an unfortunate abbreviation and name that both suggest Computer Science rather than Scientific Computing. – Ben Voigt May 5 at 4:43
  • @SonictheInclusiveHedgehog: not even the slightest bit. The question has nothing to do with computer science or programming, and if you see the list of network sites listed in that link you gave us, none of them overlap with the ones suggesting in my question, except for SO. – user1271772 May 5 at 15:18
  • @BenVoigt: My question is about where scheduler questions should go. I have pointed out that about 1800 slurm questions alone, have been asked on this network. You can look at what those questions were about. I doubt any of them were about "design" or "formal analysis" or "implementation", and very few were about "selection and configuration", but you can look if you're really curious. As for your comments about SciComp, I would recommend to re-read my question because you might have missed an entire paragraph. SciComp and HPC are not the same thing though. There's HPC that's not SciComp. – user1271772 May 5 at 15:24
  • Okay, no problem. (Just wanted to ask before casting a dupe vote, and now I know I shouldn't.) – Sonic the Bracketed Hedgehog May 5 at 17:20
  • @user1271772: My comment is intended to highlight that not all questions about schedulers belong on the same site. Questions about scheduler design likely belong on Programmers.SE. Questions about formal analysis belong on CS. Questions about implementation belong on SO. Questions about selection and configuration belong on none of the above (SU is definitely acceptable, others vary depending on the exact scenario). – Ben Voigt May 5 at 17:48
  • Also, I was addressing "schedulers" not SLURM. I don't know why you treat mention of SLURM as the only metric of questions about schedulers. – Ben Voigt May 5 at 17:50
  • @BenVoigt: I understand you, but in my comment I pointed out that I doubt any of these questions were about design or formal analysis or implementation. I could be wrong, but I think far more people come here to ask questions like "is there a slurm command for submitting a job such that it will start on November 30th, rather than now?". – user1271772 May 6 at 18:45
  • @BenVoigt: The reason I was only mentioning SLURM is because (1) doing the exact same search for PBS, Torque, LoadLeveler, etc. would not make any difference .... it's not like PBS questions are more likely to go on SU and SLURM questions are more likely to go on SO ... (2) SLURM is now the most popular, all clusters I use, across the world, have switched to SLURM! – user1271772 May 6 at 18:46
  • @BenVoigt: "Questions about selection and configuration belong on none of the above" ... has there been any Area51 proposal for an HPC site? – user1271772 May 6 at 18:49
  • @user1271772: I meant "none of the sites listed in that same comment", not "none of the sites listed in the question". I suppose I should have said "none of the foregoing". Questions about selection and configuration of existing software don't belong on Computer Science or Stack Overflow or Programmers.SE. They could go on several of the sites you listed in the question, including SU, U&L, Scientific Computing, Server Fault. – Ben Voigt May 6 at 22:21
  • @BenVoigt: Out of all of those, SciComp seems most appropriate if trying to target an HPC audience, but in the data I provide in my question, SciComp has an order of magnitude fewer SLURM questions than the rest. SO and U&L have the most slurm questions, but SO is inappropriate because these are not programming questions, and U&L is not the best for scheduling questions in general, since one might be using Windows or OSX or something else. – user1271772 May 8 at 17:20
  • @Robert Cartaino, does pringing you work here even if you haven't commented yet? Has there been any Area51 proposal for HPC? When I type "hpc" and "high-performance computing" I don't see any results except for "Big Data" which actually made it to the Beta stage, but was closed due to not enough activity (which may now, 7 years later, might not be a problem for the "big data" topic anymore; and furthermore when combined with the rest of HPC that isn't necessarily "big data" related, would certainly have a lot more activity). – user1271772 May 8 at 17:27
