-E argument seams to work whit GCC and C++

Yeah, it "works". It just doesn't produce object files :)

(-E means "run preprocessor only". Extremely useful to see what the damn thing is actually trying to compile, but useless for building object files).

Quote:

Most source codes compiled whit g++ will happy compile whit GCC

That's because (a) C++ is almost a superset of C, (b) GCC *will* run the C++ compiler engine for anything called .C, .cc, .cpp, .CPP, .c++, .cp, or .cxx. If you use g++ instead, it wall *also* use the C++ compiler engine for straight .c files, but as long as you name things .cpp, there really is no difference.
(The other difference is that when you use g++ for *linking*, it automatically links in the C++ library. gcc used for linking leaves it out).

AmigaOS 4.0 uses free memory to cache disk access, although it is only used for SFS partitions

That is just AWESOME

What's wrong with the way OS3 it does it? And yes, I have put several hundred MB files in the RAM disk before now too - and not merely to make WinUAE cry!

I do not recall precisely, but either reading or writing of large files got horrifically slow. It seemed like another instance where the early AmigaOS designers considered a linked list the be-all and end-all of data structures, and ended up walking the list more than they should. And a big file makes for a big list :)

I ran into this when I wanted to test network speed by transferring a large file. IIRC, back then, my disks weren't quite capable of keeping up with the network, so I thought I'd just use the ramdisk --- only to find that transfers were several times *slower* than with the real hard disk.

Isn't drinking bears what you do *here*?

But you can write to the hd using DMA while ramdisk store requires memcpy()...

Dirty little secret --- most HD reads and writes in an updated Amithlon system also need a memcpy, because the kernel's alignment requirements for disk buffers being written in "raw" mode are tougher than Amiga applications typically supply :) But of course, those are at least native memcpys.

Anyway, needing to actually copy the data could not explain more than a tiny portion of the slowdown. It was really mindblowingly slow, on a machine which was itself rather fast....

@Ferry

This is what I mean ( $750.) for a used PPC card outrageous

Here ya go Ferry you buy one first and then I will buy one..

thats ridicules for a non warranty risk item...

Doomed to fail before its even used!


Grrrrrrrrrrrrrrrrrr...

Hi @IOWASURFER
#30
I guess I am upset that now that 4.0 maybe coming out..

Yes, I agree with you on this! Are there any hardware vendors that can meet the demand?

Not sure what you mean.

The "file system" used in the RAM disk didn't change substantially. The performance is a good deal better because the memory pools now are about 20-30 times faster in the meantime.

I suppose that RAM-Handler suffers from the same issues as FFS with regards to large files.

Sorry dude but that was one of the most pointless posts I've ever read (even more so that this one I am writing now )

What's your point exactly?

Long time no see shoe. Hi!

I think you are witnessing "variations on a theme" in many threads here and on amiga.org.
The topic seems to be the desire for a new accelerator, plain and simple.
The sub-topic discussed seems to be the legality of such a project.

Just my 2 cents.

Huh? The item your link points to is priced $350 (barely EUR 250), not $750. BTW, fair price for that kind of HW, I think.

Saluditos,

Ferrán.

The point would be hardly anyone can afford a ppc card and no one is making one
and thats about as pointless as one can get
ohhhhhhhhhh !!!
