Pure number crunching power!

[Emc2]

I've had to drop out of computer specs and news lately due to school, so I haven't been able to keep up with what's best for what lately. Simply put, I have a c++ script and a Matlab script. These scripts will be doing a recursive operation on numbers extending past 15 digits.

I need POWER!. I wish c++ could do 64-bit integers, but AFAIK, windows is still 32-bit and doesn't truely perform 64 bit operations. So I have matlab dealing with all of the 25+ digit stuff, as the functions I've created in c++ to do stuff are just too slow.

Currently in Matlab, it takes 2 minutes to process 10,000,000 numbers through the algorithm (each number takes a different number of "iterations" through the algorithm until it's done, so the above number is just an average). This means it takes hours or days to do some of the stuff I need it to do!

Even if I could cut this time by 20% I'd be happy! I currently have an AthlonXP 2100+ Thoroughbred B cpu (266 fsb?) running with 512MB 2700 DDR ram. The size of the memory isn't a problem: I only use ~300 MB max for this processing. Speed of the memory might need to be changed.

If you have suggestions, I'll need a link or something. I can't just go on hearsay, since the money buying this isn't mine and I have to justify every penny.

Thanks in advance!

ok:
P4 3.4GHz Extreme HT
2GB Corsair XMS at 4400
500GB SATA Raid-0
GIGABYTE GA-8PENXP
VapoChill Case
52x32x52 CD-RW
8x DVD+/-R/RW
ATI 9800XT 256mb
Logitech Cordless Duo
Oh yah and top of the line floppy and power cord

How does that sound for keepin the budget down?

LMAO I think just upgrade CPU and maybe get faster ram and run it at dual channel...

BTW I just realized (doh) Corsair doesn't make 1024mb sticks running at 4400 :P

That sounds like something that only depends on the GHZ so your best be would probobally 3.4 GHZ you don't really need the EE i don't think

You would however need a new motherboard and faster ram just so it can keep up with the cpu some pc3200 or better

[Emc2]

Would an athlon 64 help better than a 32-bit counterpart? And how much does hyper-threading REALLY help?

[teengeek88]

could you possibly use a 64 bit version of linux?

just a thought

edit: i tihnk emc2 is right because hyperthreading is only for running multiple actions it doesnt help with only one right?

[Emc2]

for the c++ script, maybe. Haven't compiled it on a gcc compiler, but all of the functions I use have been created by me and use basic array manipulation alongside int*.

[MitaDC]

uhhh...I'm lost. I think it has to do with comp speed. I don't know if the HT technology would be any better cuz I am an AMD guy :P. Anyways IMO just get a faster CPU - 2800+ probably would be plenty and probaly go with 2x512mb to speed your comp up a little more. I think ram would effect it a lot.

[HeadBand]

Hyper threading won't hurt and all 800mhz fsb cpus have it so why not turn it on

[teengeek88]

lol i have no idea about what your talking about to tell you the truth i just know u wanted the 64 bit windows version (which isnt out) so i figured id tell ya about the linux

the linux would probably be more stable as well?

[teengeek88]

wouldnt you go with the 3000+ or 3200+ because of the fsb/cache increase?
