I'm interested in helping with this.
I'm taking a course this semester on high performance computing, and adding
MPI or OpenMP support to an existing system might be a good project to help
me learn more about these frameworks.
I'm totally new to OpenMP and MPI, but competent in C, and not scared by
My 2 cents, this should not be part of the J engine, but implemented as a
library.
It appears that NumPy itself implements .npy conversion as a library:

One case I was thinking of where laziness makes things more complicated in
python is 'map'. In (eager) J, I can say 2 * 3 4 5 and get back 6 8 10. But
in python, map([3,4,5], lambda x:2*x) returns an iterator object (I think). To
eagerly evaluate and return the data, I need to wrap the whole
I don't have much to add to this other than some jargon and opinions. In
Haskell (and Clojure maybe?) this type of "only evaluate the asked-for portion
of an infinite sequence" idea is called "lazy evaluation", in contrast with
"eager evaluation" used by pretty much every other language.

That's good to know, if there was an aarch64 binary that's what I would be
using right now on my laptop.
As a stopgap, it is possible to run the unmodified j80x_raspi binary on
aarch64, at least on Ubuntu:
sudo dpkg --add-architecture armhf
sudo apt-get update
sudo apt-get install libedit-dev:ar
Excellent, thank you.

Is J's reference counting implementation contained within in m.h and m.c?
I've followed some of the discussion regarding refcounting and its
tradeoffs in the Kona language [1], and would like to grasp how it's done
in J.
Thanks,
