AROS SMP Research: Technical Discussion

@Ezrec
You have already proved some people wrong with your experiments.

How so?

Lets just wait and see what comes of it.

What's that supposed to mean?

:confused:

I merely asked matthey to clarify his "You have already proved some people wrong with your experiments" statement.

Some people said you couldn't do SMP with exec.

Wasn't the issue rather about SMP and full Amiga backward compatibility?

Either you have full compatibility, or software needs to be built for your particular system, right? If the latter, wouldn't it be better to take the opportunity to create a new multithreaded SMP environment/API once and for all (together with proper memory protection, 64-bit, etc while you're at it)? A "little" more work of course , but if you are making a "new" system anyway, why don't go all the way?

It's an interesting little AROS experiment though, and maybe something that's usable for real for AROS will come out of it eventually, who knows? I just wanted a clarification about the "proved people wrong" statement!

Some people said that SMP couldn't be done with AmigaOS.

I don't think anyone has claimed that SMP couldn't be done in a situation where the precondition is that SW base is being built explicitly for that system? Rather the opposite, actually; this is a given! What "people" said is that true SMP can't be done without breaking the Amiga compatibility, which I suppose is a more relevant issue on MorphOS/OS4 than on AROS anyway, since the latter has been CPU/ISA agnostic since pretty much the beginning hence most people are happy to either run AROS builds of whatever SW they use, or run it in an UAE environment.
