Dear Graeme,
yes, I need it just for x86 and amd64 CPU.
It would be perfect if the actual thread implementation would be unified
using fpc threads. Anyway my first goal is to have a fpc/lazarus
implementation for windows and linux 32/64.
Let me know,
Andrea

Indeed. If you limit the scope to x86 and amd64 CPU's then the port
shouldn't be too hard. Can you confirm is these are the only CPU types
you want to target?
Andrea, I mig
Leledumbo has already demonstrated that the fact that mrmath is written
in assembler is likely to be an insurmountable problem.
If there were a version that was buildable (at least initially) without
using assembler you might get somewhere.

I am evaluating to propose a bounty (150 euro) to make mrmath fully

How can I do that?

That is why I mentioned the Thread-pool implementation. It uses just
TThread and hence is as cross-platform as fpc is.

Both of those could possible be made obsolete by using FPC's
cross-platform support - even for threading. So you could end up with

I can't think why that would be difficult at all. It should be all
non-gui code, maybe TThread usage. The only possible difficulty I can
see is if ASM was used instead of pure Object Pascal.

I don't think this has much to do with Pascal, it's entirely down to the
selection of a suit

the most beautiful since you have to mess with ifdefs.

For this it's essential to use the multiple cores the hardware
provides. So the task needs to be distributed to multiple threads.
If you look at the code, you'll see that it does that.
mrmath uses multiple threads and matrix operations are written in asm.
It is the fastest solution I found

It sounds like you would need something made for mathmatical processing like
fortran or even lisp. However, takin

Dear all,
I am looking for units/packages to deal with numerical matrix
