avo VS zig

I thought the /r/golang comments on this post were pretty useful[1]. They also introduced me to avo[2], a tool for generating x86 assembly from go that I hadn't seen before. There are some examples listed on the avo github page for generating AVX512 instructions with avo.

For writing AVX512 from scratch avo is a much better alternative.

Avo is a library that simplifies writing complex go assembly, I found it very useful to figure out how instructions map onto Go's asm syntax. But you could definitely do the translation directly, it's what c2goasm did (couldn't get it to work reliably unfortunately).

Curious if you're looking at using avo to write the assembly

You can use github.com/mmcloughlin/avo for generating the assembly use Go.

For normal and "better" mode I am using avo to generate different encoders for different input sizes, with and without Snappy compatibility. That currently outputs about 17k lines of assembly.

You could perhaps just have the Go compiler generate the assembler for your code:

go tool compile -S file.go > file_amd64.s

Then you could verify it doesn't change over time, and choose to begin maintaining by hand if it makes sense.

If you do want to go the route of rolling it yourself, I'd suggest looking into something like Avo: https://github.com/mmcloughlin/avo

If you have to go with Assembly, try Avo https://github.com/mmcloughlin/avo

Or is it that the three years it’s been around indicate it will never progress?

Actually it seems according to the issue that TigerBeetle (one of the bigger zig projects out there) noticed this issue [1]. It's also on their issue tracker [2].

Chapel has at least several full-time developers at Cray/HPE and (I think) the US national labs, and has had some for almost two decades. That's much more than $100k.

Chapel is also just one of many other projects broadly interested in developing new programming languages for "high performance" programming. Out of that large field, Chapel is not especially related to the specific ideas or design goals of Mojo. Much more related are things like Codon (https://exaloop.io), and the metaprogramming models in Terra (https://terralang.org), Nim (https://nim-lang.org), and Zig (https://ziglang.org).

But Chapel is great! It has a lot of good ideas, especially for distributed-memory programming, which is its historical focus. It is more related to Legion (https://legion.stanford.edu, https://regent-lang.org), parallel & distributed Fortran, ZPL, etc.

The answer was given by the Elixir community with burrito which enables users to pack up everything an Elixir application needs within a binary namely Zig Archiver to package the binary and Zig Wrapper that wraps the Erlang Virtual Machine to be used in multiple platforms (Zig + Rust in the same project 🤯).

Do not try implementing something by yourself, especially if you are like me ( loosing motivation instantly if something goes wrong ). So what to do ? Go to std , just try copying implementations from there. This leads to solid understanding how to write right code. If you don't understand something you can always go to documentation ( 2 ) and look there or into std itself and just discover tests that are written for specific structs, they really help a lot.

If you're not familiar, Zig is a low-level general purpose programming language that provides improved safety over C/C++ and powerful compile-time meta-programming called "comptime".

There's support for this type of OOM testing in Zig's std.testing:
