weave VS roast

GPU drivers provide an event system:

- Cuda: https://github.com/mratsim/weave/issues/133

```

Note: the Theoretical peak limit is hardcoded and used my previous machine i9-9980XE.

It maybe that your BLAS library is not named libopenblas.so, you can change that here: https://github.com/mratsim/laser/blob/master/benchmarks/thir...

Implementation is in this folder: https://github.com/mratsim/laser/tree/master/laser/primitive...

in particular, tiling, cache and register optimization: https://github.com/mratsim/laser/blob/master/laser/primitive...

AVX512 code generator: https://github.com/mratsim/laser/blob/master/laser/primitive...

And generic Scalar/SSE/AVX/AVX2/AVX512 microkernel generator (this is Nim macros to generate code at compile-time): https://github.com/mratsim/laser/blob/master/laser/primitive...

I'll come back later with details on how to use my custom HPC threadpool Weave instead of OpenMP (https://github.com/mratsim/weave/tree/master/benchmarks/matm...)

In my benchmarks, Nim is faster than Rust:

- multithreading runtime (i.e Rayon vs Weave https://github.com/mratsim/weave)

- Cryptography: https://hackmd.io/@gnark/eccbench#Pairing

- Scientific computing / matrix multiplication: https://github.com/bluss/matrixmultiply/issues/34#issuecomme...

There is no inherent reason why a Nim program would be slower than Rust.

If you're interested into diving into this I have reviewed solutions to cactus stacks / split stacks here https://github.com/mratsim/weave/blob/master/weave/memory/multithreaded_memory_management.md

23. Raku - $79,448

Pakku is a package manager for the Raku Programming Language. Latest releases of Pakku are part of Pakku Celastrina version family. Celastrina name means elegant and beutiful, So I will take the opportunity to introduce how elegant IMO Pakku handles Raku distributions.

At the last European Perl Conference I proposed to change the name of "Perl 6". After a lot of discussion, it was decided that it was going to be called the Raku Programming Language.

Raku note: This language has no length method on strings, because in Unicode world it is super confusing. Instead there are separate methods to ask precisely about amount of characters, amount of code points and amount of bytes.

Elizabeth Mattijsen reports on all recent developments around Rakudo, an implementation of the Raku Programming Language.

The raku.org website.

This became one of the first things that needed to be done, to be able to say the new implementation would be matching the old. During the development of these tests, it became clear there were some inconsistencies in the existing implementation, and worse: outright bugs.
