array VS gobasic

I should have mentioned somewhere, I disabled threading for OpenBLAS, so it is comparing one thread to one thread. Parallelism would be easy to add, but I tend to want the thread parallelism outside code like this anyways.

As for the inner loop not being well optimized... the disassembly looks like the same basic thing as OpenBLAS. There's disassembly in the comments of that file to show what code it generates, I'd love to know what you think is lacking! The only difference between the one I linked and this is prefetching and outer loop ordering: https://github.com/dsharlet/array/blob/master/examples/linea...

If you are looking for something like this in C++, here's my attempt at implementing it: https://github.com/dsharlet/array#einstein-reductions

It doesn't do any automatic optimization of the loops like some of the projects linked in this thread, but, it provides all the tools needed for humans to express the code in a way that a good compiler can turn it into really good code.

There are a bunch of BASIC interpreters out there, my own isn't so complex or thorough, but I definitely had fun writing it:

My own vision was to reproduce something akin to the ZX Spectrum, rather than the more advanced Microsoft BASIC.

Unusable might be a bit harsh, but I have to say that when I wrote my own BASIC interpreter last year I deliberately concentrated on the line-numbers and facilities of the ZX Spectrum I remembered:

Being standalone it doesn't have the graphic support or the interactivity, but it was still a fun project to work upon.

I wrote a simple BASIC too, for nothing more than a sense of nostalgia:
