those that are using seti with a HT enabled cpu

i noticed that when i run seti@home and processing only 1 unit, my cpu utilization is only 50%

do you guys process 2 units in order to utilize 100% or just leave it at 1 unit?

thanks!

 
I dont personally have one, but i think it was said that there was a 20-30% increase in output if you run it with 2 processes?

If i'm wrong, someone please correct me.🙂

Huh??

Since when did you start using P4s ?? 😕
Nice o/c there!!

maximum processes: 2
set processor affinity: checked
 
Definately run 2 processes. I've never found the "processor affinity" check to do anything so I leave it unchecked.

my times are pretty crappy right now because of my fsb....

i'm running a fsb of around 190 right now due to the fact that my ram can't handle the 5:4 divider...

once i get my geil gold dragon pc3700 i am going to run the 5:4 divider which willl put me at a fsb of 234 🙂

and my wu/day should go up (i hope)

Alright, I'm confused...how are you getting 3.5Ghz from that 2.4c if you have you FSB at 190?

edit alright...did a few common sense calculations... you are not running your fsb at 190 right now. your memory is running at 190Mhz right now (DDR380) at the 3:2 multiplier....so your FSB is ~285.
285x12=3420Mhz 285/3*2=190RAM Mhz (DDR380)
285x12=3420Mhz 285/5*4=228RAM Mhz (DDR456)

Don't worry about the wu times.....worry about wu quantity. You should be getting 15-20 wu's/day from that system running 2 processes.

my bad... my fsb is at 195 not 190

293 * 2/3 = 195

thanks for pointing that out


 
so yeah...

looks like my WU/day has increased from about 11-12 to 18 now!

average time for a WU has increased from 2:11 to 2:50ish

wow... can't believe i'm crunching six more units a day now...
 
So lemme get this straight... with just one process running, you were doing 11-12 WU's a day... is that with it running 24/7? And is your 18 WU's with two processes running 24/7?

i think i over-estimated slightly....

i saw my WU/day go up about 6 units when i switched from my amd to my p4...

it may have been due to some high AR Wu's...

amd = 1 unit processed
p4 = 2 units processed

interesting results though....

p4 still crunching more units/day though than my amd setup that's for sure...
 
I find that odd that a 3.5 Ghz P4 can't do more than that... do you run it 24/7? Cause my processor takes 2 hours 10 minutes for one WU.
 
you should be crunching WU's in about 3hrs @ 3ghz according to tomshardware
http://www.tomshardware.com/cpu/200...ml#distributed_computing_seti_text_client_304
Keep in mind he is running 2 clients and has taken the time of 1 job and divided it by 2.

People say Async and Sync modes dont matter on the canterwood but i think there is a small impact on certain apps. I noticed that on my 2.6c when run in Async mode takeslonger to load in WarCraft3 Ive tested this on my home lan with the same 3 boxes and whenever Async is on for canterwood my AMD box (xp1700 @2013mhz 175mhz fsb nforce2 sync)loads faster. Both the AMD rig and the intel box have the same exact model HD's. When the canterwood is in sync mode 1:1 it loads much faster then my AMD box.

Mabey somebody who knows a bit more about canterwoods Async/Sync ram operation could fill us in, but i believe this may be why your not crunching as fast as you could. Or you could test it and post results here =) I dont run seti or i would test it. As for myself im going to ditch my hyperX ram and buy some of this new PC4000 so i can run at 3.25ghz in sync mode
 
yes i run it 24/7

i average about 11-12 WU's a day.. maybe possibly more.. i'm not quite sure yet...

i'll do tests... see how many i can do in a 72 hour period or something with and w/o HT enabled

average time right now is 2:29 but that was including when i was processing 2 at a time and was averaging over 3 hours per unit...


 
On my 3.2GHz Dell (No tweakable settings 🙁 ), I'm getting an average of 16 to 17 WU's per day with an average time of 2:58 per WU. Not bad considering that ONE processor is running TWO WU's at one time! 🙂

Running Dual Channel PC3200 at 3-3-3 with ECC enabled (no choice 🙁 )!
 
ahh so maybe my 18 WU wasn't a fluke then huh?

man...

i cant wait to get windows xp so i can make use of this HT processor!
 
I was able to get as high as 16wu per day. It had an average of 14 workunits per day while running Windows XP Pro.

Now, I dumped Windows XP Pro and installed Windows 2000 Pro. HT is still enabled. SETI Driver defaulted to 2 processes of SETI.

The cost of 1 HT enabled 800MHz FSB Intel machine is higher than a dual Barton. When I run 2 processes of SETI and start Commanche 4, the playback of the graphics on the AIW 9000 Pro is not as smooth. In fact, if I record DVD quality video while running 2 SETI processes, the results will be a poor video recording.

I had to reduced the number of SETI process to one so that the recording is smooth. On the dual Barton, I can keep SETI running on both CPU and still manage to record good DVD quality videos.

One of the advantage of using the HT enabled Pentium 4 is that my room is much cooler than when I have the dual AMD system. (less noise too🙂)
