A coworker brought this list to my attention:
https://xstackwiki.modelado.org/DSL%27s
The work on such DSLs (reminiscent of Don's work on optimizing
matrix operations years ago) seems be on the rise.
I didn't know most of them.
I encourage everybody interested in Image/Signal Processing to
have a look at Halide
Talk https://www.youtube.com/watch?v=3uiEyEKji0M
papers http://halide-lang.org/
I don't know if it's already available in the source code but
they mention the scheduling part can now be optimized through
genetic algorithms : the code will autotune to use the best of
your hardware, exploring the space of precomputing (stencil
buffer), inlining, multithreading, vectorization, unrolling,
sliding window ...
Thanks for sharing Andrei :)
Halide looks just *mind-blowing* though I couldn't find any
project using it on github (other than toy-examples). I couldn't
find anything either in the doc about the automatic scheduling
they mention in their paper. I am wondering if it is possible to
perform linalg operations, it seems rather convolution-oriented.
Anyway, it would be awesome to have a D front-end (not that I
have the time to code it, I usually just talk ;)).
Else :
Preferably to DSLs though, I am more waiting something as basic
as containers based on std.allocator or a standard
multi-dimensional array (with range behaviour based on a
permutation of the dimensions and allow borrowed slices of any
subspace). Well in fact I am not waiting since I do not have the
time to code in D but if I had the time this is what I would be
waiting/working for. Keep it up !
