NuMojo V0.2 Release: Simplified Type Handling, New Features, and Enhanced Compatibility
While magic is getting worked on, is the recommendation for development to build a mojopkg of the dependency and place it in the source tree?

Traits with compile-time SIMD size
I'll work something up that is a bit more complete. I am trying to infer W when passing the engine into the
PRNG. I can see that it will probably work if I write it the dimensions explicitly everywhere.9 replies

Traits with compile-time SIMD size
I tried that a bunch of different ways. When I parameterize
PRNG as PRNG[T: PRNGEngine], I can't seem to resolve W.9 replies

Specialize on trait
Thanks. I found it in the changelog. But your example is clearer.

Random123: Splittable pseudorandom number generators
Interesting. Splittable sounds ideal for a lot of uses. Do you generate a deterministic sequence of keys from an initial seed in each code block? I ran across this: https://github.com/ElsevierSoftwareX/SOFTX-D-23-00704

Random123: Splittable pseudorandom number generators
That does sound different. I've used xoshoro et al. in large MPI applications where each process gets its own prng, all seeded from a common global seed, but each process jumps according to its MPI rank, thus providing reproducible results with independent streams running in parallel.

Random123: Splittable pseudorandom number generators
I don't know if the use cases are similar. I ported the xoshiro256 prngs to mojo. You can jump the streams to produce multiple independent sequences. These can be computed in parallel using SIMD. https://github.com/Mojo-Numerics-and-Algorithms-group/MojoSci/blob/main/src/stochasticity/xoshiro.mojo

Parameterized function definitions in traits
Ah. I just needed to update to the latest nightly.
Edit: Actually, that was not the fix. I was trying to specialize in the type definition, but specialization occurs at the point of invocation, so the trait requirements have to be duplicated exactly in the type.

NuMojo Moved into a GitHub Organization Updated to Include access to different backends
Yes, I could do that. It would be good to get the package/module/naming structure right early on. In the R world, packages are fairly broad. Seems that way in Python as well. Rust on the other hand often has quite small and single purpose packages.

NuMojo Moved into a GitHub Organization Updated to Include access to different backends
I'd be happy to chat about this. I'm working on some codes related to my research. So far, I have ported the xo(or)shiro prng's to native mojo, implemented a toy static matrix (awaiting someone to port Eigen or similar to mojo), and started on some RK integration methods. I also used
numojo but changed it to mojosci as I don't prefer numojo. Perhaps we can think of a better name. It may be too soon to create a working group. Seems to be an army-of-one at the moment. 🙂 I'm happy to think about this. Mojo is the language I have always wanted for scientific computing (way too much time in R and C++; I like Julia in broad-strokes, but I don't like the type-system). We should definitely plan a mojo science conference or side-session in the coming years.7 replies

dynamic traits are not supported yet
Dunno. But I sure could use generic traits already.

MAC Docker Setup - Could someone help with it?
Out of curiosity, I just tried this:

docker run -it debian:latest /bin/bash apt install curl libedit2 curl -s https://get.modular.com | sh - and it worked. The modular script misses the libedit2 install. To clarify, what worked was

modular install mojo. I did not try anything else.6 replies
