What is the current state of multi-threaded BLAS in Julia?

[adienes]

though do be aware that Octavian.jl is soon deprecated

Why is LoopVectorization deprecated?

Polyester.jl doesn’t depend on LoopVectorization.jl or VectorizationBase.jl, but I think one of the same problems Julia 1.11 introduces impacts it as well, so we shall see. Octavian.jl depends heavily on LV, so it is dead without it. Tullio.jl will still work and be multithreaded, but performance will suffer for a lot CPU code using it without LV.
