World: r3wp

I suspect BrianH, Maxim and Cyphre wake up when the host code is 
released. That'll be enough for me. :-)

See the blog :)

Cyphre, onmy computer  with your mandelbrot-int.r script i get :

rebol 2 VM 2.7.6.31 : 0:00:03.904
rebol 3 (2.100.95a): REBOL Elapsed 0:00:04.354   


my computer in intel core i5  750 , 4Go DDR3 1333MHz Gygabyte P55UD3 
 

so maybe you should upgrade  ( and i'm sur where i lost most of the 
time where in the consol exists)

(oh and i had a 3D game running on the computer at same time...)

question is ... rebol is actually developed for deprecated hardware 
or for tomorow's hardware ?

R3 64bit builds should be optimized for tomorrow's hardware. The 
32bit builds should be optimized for netbooks.

but to run the 64 bit version you need to have windows 7 64 bit which 
is francly useless when 99% of your softwares are still 32 bits....

So far, we only have 32bit builds, and there has only been one optimized 
version, likely not the final settings either.

Or Linux 64bit, or OS X 10.6, or....  We will have both 64bit and 
32bit REBOL builds. Use the one that suits you best.

yeah but i like the  benchmarks based on deprecated harware ... as 
you could see  on a today's computer (and not even to top mark one) 
 the gap betwin R2 and R3 isn't so wide as stated by cyphre...

brianH the only  OS where it means something to be in 64 bit is linux 
.... because you havec access to 

the source code of most of you software including the linux kernel 
and you can recompile them to optimise them to your hardware. With 
this important limitation ....as linux is not industry supported 
most of now in day hardware isn't full power supported ... so the 
optimisation part goes to waste...

For new hardware, the platforms limited to 32bit tend to be the ones 
where performance is a problem. If you want to run 32bit code on 
anything other than a netbook, then your hardware is overkill. The 
big boxes are switching to 64bit. And it matters a lot for R3 since 
integer math is 64bit even on 32bit builds.

yeah but this means you posses the drivers and the user end software 
that goes with you brand new 64 bit os and hardware

Windows has been going 64bit since XP/2003, and is going that way 
in a big way with 7/2008r2. OS X is going 64bit with 10.6 - 32bit 
only matters for 10.5 and below. Only on Linux is 64bit a problem, 
mostly for 32bit backwards compatibility.

brianH and since then the windows 64  bits is more than a candestine 
OS ... (i'm asking myself if windows OSes  in 64 bit are more used 
on eath than rebol or not ...)

I do possess the drivers and software for my years-old legacy hardware 
that runs 64bit Win7 just fine.

Most new computers with Win7 installations are in 64bit, since 32bit 
apps run without difficulty on 64bit Windows. 32bit Windows is only 
being installed on netbooks and bitty boxes that would benefit from 
netbook optimizations.

New Macs are all 64bit, no exceptions. All Intel Macs can run 64bit 
code, and do once upgraded to 10.6.

Soon, most 32bit Macs will be PPC.

PPC ?  i thought they droped those PowerPC design some years ago 
for intel ones

Yes, and people still se them. Deprecated doesn't mean the existing 
ones magically fail to function. Mine works just fine.

Linux and the other non-Mac Unix-alikes, and the obscure OS's are 
the only ones that are sticking with 32bit, mostly because they are 
terrible at running 32bit code from their 64bit versions. Windows 
and Mac 64bit run 32bit code just fine now.

but on most of those os you can recompile most of the software which 
is impossible on windows

then the lack i more about the new drivers than on the 64 bits 32 
 bits compatibility since you can do ./configure ; smake all ; make 
install

You might not have noticed, but many applications for Windows have 
been releasing 64bit builds recently. Just because *you* can't recompile 
the software doesn't mean that the developers of the software can't 
and won't. Most do, except the .NET or Java apps that don't need 
to be. As for drivers, a simple configure, make, install won't work 
unless the code was written and tested in 64bit mode. Having a 64bit 
OS that will easily run 32bit binaries without complaint is better 
that requiring the users to do a recompile (and likely rewrite) of 
the application.

yeah but 90% of them are not

that reminds me when my university bough dec apha 64 workstations 
back in  1998 question was what os we take ....Windows XP 64 then 
we don't have most of the drivers and softwares in 64 bits but the 
32 bits emulation is good... Do we take Digital UX 64 ?  then we 
have the drivers in 64 bits but we  don't have access to most of 
the common software people use.

or do we use linux  64 bit .... if we don't have something then we 
can create it and i though our university purpose was to create and 
maintain software ?

so we went for a debian 64 bit  home made os and that was perfect

I wouldn't know - I haven't found a piece of hardware made after 
64bit CPUs came out (many years ago) that I can't get to work on 
Win7 64bit, even if it means using XP 64bit drivers Only one peice 
of hardware didn't have drivers built in. My friend found one 10-year 
old piece of audio hardware that won't work in anything past XP, 
even 32bit Perhaps your mileage may vary, but I doubt it. And the 
few applications that I use that don't have 64bit versions work without 
problems, even in 32bit.

on the "server"  a digital dec 50 we kept the digital UX with an 
adapter X11 server to broadcast the Xterminal sessions ...

(sorry, some periods missing apparently)

and handle the students accounts

for example you can seee how intel and amd marketise the 64 bit capabilities 
of their main processors ...

Win7 supports 32bit Windows Explorer extensions in 64bit Windows 
Explorer. I don't even know how that  works, but it does

a part for intel Xeon which is the server version and obvious 64 
bit version processor it's hard to know what  is the adress / integer 
lenght in the other processor

but amd  label their processors with the 64 stamp

i don't use windows explorer .... so that's not the problem

AMD's processors are 64bit, except the Semprons for the bitty boxes. 
Only Intel has been skimping on 64bit.

and sempron like duron are made for laptops

Nope, Sempron is their budget brand. They have laptop and desktop 
versions.

If you are on Windows, it is too bad if you are not using Windows 
Explorer. Explorer extensions are the most useful thing on Windows.

i'm not i'm using viva firefox ... explorer 8 is a shit ....

Windows Explorer, not Internet Explorer. It's the file manager.

And the UI, and the Start Menu, and...

same the file manager  embeded is boring ... i prefere using freecommander

and the included Zip is slow  so i prefere using 7-ZIP

Oh well, you are missing out on the best tools for Windows. Including 
7-Zip, which is easier to use from Explorer than its own UI.

not at all i'm getting all the regular extensions in free commander 
without the blue screens of death

and free commander evolve faster than once in ten years like the 
windows explorer
