On my MacBook Pro, I have encountered a number of kernel crashes while running the ‘solve’ command from the DifferentialEquations.jl package. One such situation occurs when I run the exact code from Example 3 here: Ordinary Differential Equations I have tried with ‘vanilla’ Julia, with JuliaPro, wi…

That should have been solved on the latest VectorizationBase, because it should now be querying LLVM for the supported instructions rather than checking the actual CPU. Perhaps RecursiveFactorization should set a lower bound on this VectorizationBase version? @perseid28 mind adding VectorizationBa…

[image] Elrod: Perhaps RecursiveFactorization should set a lower bound on this VectorizationBase version? yeah we should probably add that.

I can make a PR. I’ll make it a later release to also add a check for if they aren’t using the usual LLVM (e.g., installed using Gentoo’s package manager). While I hope folks don’t do that, if it’s easy enough to support…

[image] Elrod: In case you’re curious about the problem: this CPU has a lot of new features, but because of how Apple does something, LLVM doesn’t recognize this and therefore cannot/will not use them. That bug should be fixed in Julia master, but VectorizationBase probably should have been chec…

Do you mind to try out Julia nightly Julia Downloads (nightly binaries) ? It should work after https://github.com/JuliaLang/julia/pull/36330 , but since I don’t have Apple hardware, I cannot test it.

[image] perseid28: Thanks, that is good to know. I haven’t used Julia in a few months but this experience of it not “just working” was something new. In regards to your advice, I added VectorizationBase, v.0.12.12, but even after adding the package to my code I get the crash on the solve() call.…

Could you also post the result of using Pkg; Pkg.pkg"st -m" please? By the way, it’s easier for others to read if you quote the output with triple-backticks ```, see Please read: make it easier to help you for more details.
