I had some students come ask me about implementing material from my numerical analysis course (which used Julia) in part of their Rust student group. I’m not an expert, but my feeling is that Rust is a “safer” language, which to me means it must be slower. That is, Rust is designed for “systems” whe…

I think I should recap what was discussed (as I understand it): The cost of bounds checking can be avoided in Rust by compile-time “proofs” of correctness, which are somehow done in the type system. There is also get_unchecked, which is unsafe. So I think the conclusion is that it is possible to a…

Yea, this and the dynamicity of Julia and other stuff are why this is harder than just translating rust’s traits verbatim… but I’m wondering if this is a fundamental gulf or is it fruitful to explore the safety vs flexibility tradeoff, especially as an opt in thing. [image] tkf: I don’t think d…

You might want to reconsider your assumption that Rust’s memory safety makes it slow. It’s one of the fastest languages available, partly because of, rather than in spite of, the memory safety. See these benchmarks: https://github.com/drujensen/fib . What Rust runs in 7.652 s, Julia runs in 11.318…

While I agree that Rust is certainly not a slow language, and it’s memory model can sometimes be quite helpful for that performance, I don’t think a benchmark on the recursive Fibonacci sequence is really that great a demonstration of this point.

Well, one of the main objective of Julia is to solve the two-language problem and provide scientist with fast and productive language. With this in mind, exposing Julia function to Python is less important than exposing rust function to Python.

Especially since the fib microbenchmark doesn’t involve arrays at all…

The main problem with Rust right now is that, as far as I know, there is no support for parallelism con clusters. Even the MPI wrapper crate has had no commits in 4 years. I would love to try Rust on my project but unfortunately I need it to run on a cluster.

I think, this comparison is unfaire. You are comparing library not language itself. I believe there are handful of rust library can do this as simple as julia.

Regarding to two language problem resolver. In my opinion I think Rust is better suited here. As there provide similar abstraction. But rust is GC free. Which make it capable to write super fast program, this is the reason why it suitable for system program development. Here is the computing model …

Rust is a systems programming language with its core feature memory safety. It might be a very successful tool for systems programming and for writing safe and efficient code for huge libraries. For scientific computing applications, OTOH, a language without arrays support as first class citizens is…

[image] calbaker: I’m not sure about Julia, but Rust’s pyo3 package (crate) makes it really easy to expose Rust functions, structs (classes), and methods to python. I’d be shocked if there’s not something similar for julia. There is not anything similar for Julia. On an absolute scale, people…
