Hi,

My current computer is an ibook G4, but i need more horsepower for my desktop pc. I use my linux desktop primarly for programming (and compiling).
So I was thinking about buying a new mac like an 2 x 2 Ghz Powermac G5. It cost's +- 2000 euro's. :D
On the other side, you can buy for that price 4 1,25 GHz G4's or 3 1,42 GHz G4 mac mini's. 8)

Somebody experience with linux-clustering for desktop use ?

Isn't compiling the only thing that really requires horse power, when programming?

How about using distcc for distributed compilation?
That should run on x86 and ppc, you should be able to run almost any machine available.

If you would write cross platform software a dual opteron is obviously the best deal.

It's not like Mac OS X is anything special as a development environment. All you need is X, gvim, and gcc or python :P

In my opinion buy a powermac. It is 64bit arch, better than 32 :-) (think at the future)

it's for real time aplications i think
so you don't care about power cosumation...
http://www.anandtech.com/linux/showdoc.aspx?i=2271&p=10
you couls buy some xbox
i think you'll find some for less than 100$(if you leave in the us)
you could also buy some sempron 754 and overclock them a lot...
you could also think about changing your compiler(gcc) to a more recent version for using the 128 bit vector of G5s or use intel compiler that makes more use of this in x86 cpu than GCC
is the floating point unit used in compilation???
if you could use it...there is a guy that have made a languadge for using the chip of his graphic card ...

i'm also thinking about clusteringg for some projects...but i'm planing of making them run 24h/24
(mostly mathematical calculations)

And have segfaults all over the place. Overclocking is a very good technique to build applications that will randomly screw up your system.

Indeed. A stock dual opteron is a much better idea than a small cluster of overclocked semprons.

Well, if I wanted more horsepower in a PPC and could wait until November, I'd get one of these:
http://www.xbox.com/en-US/xbox360/

And if it appears with the rumoured $300 pricetag (for the barebones version) I'll gleefully leap to the bleeding edge to get Linux working on it.

Ars Technica has details:
http://arstechnica.com/articles/paedia/cpu/xbox360-1.ars

The relevant part is:
3 symmetrical PowerPC cores running at 3.2 GHz each
2 hardware threads per core; 6 threads total

OOoooh, I can't wait.

i was thinking about the fact that sometimes there are componants as arm processor in sound card or think like this
so...
could we run linux on an other processor to use the main processor(sempron) without switching thread???
the overclocking of sempron is safe if you test your system stability...
mabe some a64 if they are cheap...

Just wondering.

If you can buy 3 powerful CPU's for almost $300 in November in an XBox. Why is an ibook or powerbook comparitively
so expensive with what looks like weak cpu offerings?

I would love to own an ibook or powerbook, but when you are not a mac os fanatic or graphic artist then the
apple tax look to be more like extortion than anything else.

because linux into xbox wont come in november
because of copy protection built into the processor it would be very dificult to port linux into it
so there is to wait for ps3(mabe coming with linux)
but...
there is still the power consomation issue...
a mac mini consume something like 20W(aproximtely don't remember the exact number)
knowing the fact that you could remove the cd-rom drive it would consume less
and you could also sell them to some people interesting in case moding/tunning
you could also buy it without the mac-os but it depeds on the law of your country
(doesn't know the power consumatin of an xbox or a ps3)

-a power mac cost 2000E(remove price of software and service if the law permit it and if you don't want it)
-2 imac cost 1300E*2(remove 2x the price of software and service if the law permit it and if you don't want it)
-4 mac mini cost 2000E(remove 4x the price of software and service if the law permit it and if you don't want it and 4x the cost of the seled dvd-drive)
you need also some switch and cable on some configuration

mabe you could buy them without ram,graphic card...(dont know if the law permit it because it's hardware,not software) nd buy some pc hardware instead(don't know if moding is absolutely necessary for graphic card,because i don't kknow if it's a bios or an os issue)

Why not buy a dual opteron.. install gentoo/linux/*BSD on it... and then SSH into it from your PPC?

That way, you can run OS X in MOL on your PPC, and gentoo linux... AND you can have access to your opteron's computing power via a network connection.

(It's also nice if you have a powerbook... because it's more of a 'set it and forget it' type of thing. And then you can run around with your powerbook, still have access to all your email/programs and whatever, and they won't be bogged down by the intensive calculations in the background)

Game console makers don't earn money with the consoles they sell, they earn money because game producers have to pay them a lot for licenses to make games on those consoles. I think it's the same with cheap inkjet printer, they don't earn a lot with the printers themselves, they earn by selling the ink for those printers. Also, the xbox isn't exactly the same like a laptop....

The apple tax looks like extortion ?!? Let me ask you something.. did you ever check out the Apple store to see how much an ibook costs? And did you compare it to similar models from IBM, Dell, Toshiba? Did you do the same for a Powerbook ?

@kubrick

i would go for the dual powermac G5 2x2Ghz. for sure.

you must compare their power...under linux
the power mac 2x2GHz are great but it cost a lot...

THe G4/G5s have a much smaller die size, but they aren't produced on such a large scale, like the x86 processors are.

So they have a 'price premium' accociated with them, not to mention the expensive water-cooling that goes into the G5 setups.
