@hannorein That would be a bad idea especially if someone wants to run REBOUND on an #HPC cluster.
Dealing with simulations that create tons of files will put a lot of extra load on the shared file systems.
On your own little cluster, you probably wouldn't notice, but on the Alliance's national systems, on which thousands of users are working at any given time, this all stacks up.

Why not use something based on #HDF4 or #NETCDF?

I am starting getting good results.
It’s almost good enough to ditch Panoply, at the least for my basic needs with #netcdf.
I guess I am going to write a native macOS app to quickly visualise #netcdf files.

Late night coding session. Trying to figure out a workaround for plotting a very large (226 million) array of structure members without running into memory trouble. Somehow discovered a class hiding in the library API for getting the data in sections, and, WTF, worked on the first try. And memory error avoided, woot!

Friday afternoon and late night were a fun experience of updating code to 1) override the code signature of a newly introduced 3rd-party native binary included in a Java library, and 2) extend a JNI class to add a new filechooser method. And I mean "fun" in the most enjoyable nerdy way, because I haven't been there in a while. Just working through both issues seems like work getting done, even if no one else will be able to use the result for (just, I hope) a couple weeks.

And if anyone noticed the #netcdf / CDL syntax highlighting, I have a couple of things to tick off before I do a proper launch in the very near future, but see here: https://github.com/jatkinson1000/tree-sitter-cdl

Whilst digging through #netcdf this has got to be one of the best unit #tests I've seen in a long time. πŸ˜‚

Yay! Just discovered via Github that Unidata received its latest funding tranche and their developers are back to work!
