I wrote a post using #PDL for extraction of line features from images using a Hough transform. Hopefully, it shows PDL's capability for working with ndarrays (even though this is just 2D in both the image and parameter space).
My paper about the @metacpan module Task::MemManager is done!

, showing how one can use the module to share memory between components of multi-language (#C #assembly , #Perl , #PDL) applications .
The package will be discussed in a more applied context in my 2nd talk ("Quest for Performance") in which I will illustrate its use in #OpenMP #C / #Perl @openmp_arb workflows. #Fortran is next!
One of the reasons I keep dropping hints about #perlffi , #pdl and #openmp is that one can literally have five multithreading frameworks in the same #perl application of a master process: 1) PDL, and FFI intefacing with 2) #Fortran coarrays, 3) Fortran openmp, 4) #c openmp and 5) #cplusplus #openmp. All these frameworks can share memory addresses for array and vector objects, and #perl aided by #PerlAlien makes the authoring of the high-level code a pleasure ! hgpu.org/?p=29403

A couple of data/compute intensive examples using Perl Data Language (#PDL), #OpenMP, #Perl, Inline and #Python (base, #numpy, #numba). Kind of interesting to see Python eat Perl's dust and PDL being equal to numpy.
OpenMP and Perl's multithreaded #PDL array language were the clear winners here.

I saw your post here about extensible syntax <nntp.perl.org/group/perl.perl5…> and mentioned it to the #PDL team because we have a module called NiceSlice that implements a variable postfix syntax using a source filter. This obviously has problems for complex code.
We'd like something more robust and were wondering if you had any thoughts about ways we could not use a source filter and still get this working (in a lexical scope of course).

There is a nice #preprint going over #pdl its inline module PP and inline #clang
arxiv.org/abs/1702.07753
The preprint and my rudimentary benchmarks argue for revisiting #perl for #datascience applications.
Incidentally, running the benchmark under #WSL in #Windows11 gives the same performance as running it under #Ubuntu.
