Which Processor better for UD?

Scout · Mar 2, 2003

I'll admit, I haven't done any research on this, but I was wondering if any of you guys know off the top of your head which CPU works better on the UD Cancer/Smallpox resarch projects? These work units seem so variable that I can't tell from just looking at progress over time on each machine...

According to PooBaa UD uses a lot of floating-point (non-SSE2 I beleive) so in theory AMD Athlons should be better.

Rats! I just gave one of my Athlons to my wife... and kept this darn P4!!! Oh well... time to build a new one

You have too much money that you keep building PCs?

I have to agree with that. I already have 5 PCs at home... from which 3 are my own, one is for my brother and one for my dad.

I usually shop around the bargain bins and get some pretty good stuff for a song! I just picked up a cheap nForce board and have a nice little T-bred in it. This is the original nForce (not nForce2). It seems to do a few strange things, but I think I have it running stable now. The weird thing is when you change the FSB, it doesn't seem to change the bus speed, although the BIOS reports it does. How strange is that?

According to Orbi at the UD forum, it AMD,P3s then P4s in that order because as stated before, it's the FPU that does the real work.

Every working computer must be improved .... or replaced ...

Cool, that explains why my 933Mhz P3 performs almost as good as a 1.5GHz P4. Don't you love the fact that Intel says Mhz is all?

this is what i get

478 2.2ghz celeron 128k 9-12hr
478 1.7ghz celeron 128k 15-17hr
360 1.3ghz celeron 256k 10-11hr
slot1 750mhz 512k -------10-14hr

and i get crap points for realtech nic card 22 points

Scout · Mar 16, 2003

I have the same problem with the NIC... 43 points for mine... How do they figure that?

Wow... it looks like Cache makes a BIG difference doesn't it? I've Got a P4 at 2.1 with the 512 L2. I ought to check it's times against the faster (2.8 GHz.)Celeron on UD units. Hummm... I'm tryin' to remember, is there a history file somewhere of which each unit took?

I guess you connect to the internet through a LAN card. Then not the speed of the card but the total internet speed creates the NIC value. When I'm downloading stuff my nic gets 40 points when the connection is completely idle then I can get up to 60 points.

It is the only thing in my system bringing the points down. :frown:

I would be intresting to see what
a 3COM or Intel nic gets for points
??????????????????????????????

Owl · Mar 16, 2003

I think it's brand of nic,
I may be nut's but it's worth a testing,
I see some geting 200+ points HOW ????

Scout · Mar 17, 2003

I think SVOL's right.. all three of my rigs score 43 on the network rating and I have Netgear NIC's in two and an SMC NIC in the other. It's the speed of your connection I think...and mine's not very fast!

Yeah... I've you got a T1 or T3 line then you will easily get 200 points for the NIC. All my PCs get between 40-60 for points and I have Realtek, Via and a 3Com NIC (which connects the server to the LAN) in my network.

Okay, I'm installing UD... I'll keep seti running too, I dunno, I'll figure something out.

silverpig · Mar 17, 2003

Hmm, even when I set UD to Below Normal and seti to Low, seti still takes up all my cpu usage and UD gets nothing. argh.

silverpig · Mar 17, 2003

Okay, so is this good?

CPU: 1.6 GHz Athlon XP - 100 points
MEM: 512 MB DDR - 134 points
STORAGE: 0.98 GB (I'm upping to 2.5) - 20 points
NIC: Some POS - 90 points
Overall: 101 points

svol · Mar 18, 2003

Your CPU should score much higher... my 1.4Gz Athlon XP reached 120-130 points as default.
Set the storage to maximum... it will never use much of it anyway. Even if you don't have 10GB free and set it at 10GB it will give you points.

silverpig · Mar 18, 2003

Okay, now it all jumped up. My cpu was at ~140, NIC went down to 48, storage at 2.5 gigs went up to 50, ram is still at 134. I don't run it much... Just kinda fun once in a while. I'm still churning out seti units mostly.

Owl · Mar 21, 2003

Your all Right !!!!
I moved from 10T hub too 10/100 switch
and all my Nic's went to 100 points
THANKS !!!!!!!!!!!

I've never been able to get much out of trying to run two of these type of processes at once... Let me know if you think it buys you more than it looses. It seems that the multitasking would be difficult for these single thread processors.

yep. far as i can tell its 'mostly' FPU... A P4 could win, but it would ahve to have a vast excess of Mhz and memory bandwidth.
AMD's arnt all that memory bandwidth sensitive either 1.2C @ 133fsb with sdram was slightly slower than same Mhz @ 150fsb
but on a modern DDR chipset (KT333) 133/133 gives exactly the same performance as 133/166 and 166/166.

And i dont know how much but i would assume that extra cache would help... reduce the amount of main memory calls.

The topic of multitasking on SMP machines have been covered extensivly on the UD forums. Its too complex and would require a complete rewrite of the code. its far easier to run two instances of UD side by side instead.

P.S. I recently upgraded to ADSL with a dlink 504 adsl modem/switch and a NIC. my network scores are now 100, even though its only a 512/128 connection

Damn War! I'm too young to watch other people die!

How have you set your connection type? Still 56k6 modem or have you changed it to DSL?
