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:
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?
