seti and 3.2ghz (ht)

Messing with recently rec'd 3.2ghz with xp pro on top and seti via setidriver. I see the platform appears to treat the 3.2ghz processor as two processors--at least presented that way.

my question stems from the following: I am running two instances of seti/setidriver/setispy, each instance in a separate directory--treating it like a dual processor machine as I have yet to figure out how to dedicate the 3.2ghz to one instance of seti.

my problem, when one instance of seti finishes it sometimes locks-up the other or causes it to start over--zeros out the state.sah.

does anyone know what I missed? please tell me how to dedicate the 3.2ghz to one instance of seti or eliminate the cross-setidriver problem.

Thanks.

First you only need one setidriver folder. Setidriver will run 2 instances with just one install. If you only want to run one instance just change processes from 2 to one in the setting in setidriver
 
thank you!! it appears to processing two after increasing cache size to 2; however, what does the monitoring bar show me--1 or 2? what?

Thanks again.
 
First I would increase my cache to around 20 work units as fast as your machine will process them. Second setidriver will show the progess of the first work unit it started crunching, when that work unit is finished it will then switch to the second work unit which it has already been crunching which is why the progess bar will not reset to zero when the first unit work is completed instead it will go to whatever percentage the second work unit has been crunched
 
I have a setiqueue box, so I keep the cache low.

one final question: is it possible to utilize all 3.2ghz on one seti wu?

I appreciate the time; you saved me from more aggravation.

thanks again.


 
If you have network problems you will not have anything to crunch and No way to have two processes on one work unit with a ht p4 that I know of.

in theory you are, when only running one process. It's just that there are left over parts of the cpu that can still run in parallel (parallel being the operative word there). Just because the task manager only shows 50% processor usage doesn't mean it's not going full steam ahead!
 
have had very little go wrong with this home network--not much that can go wrong except power and then it matters not.

does this ht implementation mean that you get no more than 1.6ghz for any one application, max? I love dual processors machines, but they are advertised as such.

thanks again for all the help.
 
I just missed previous entry...what does that cpu usage mean, then? close to 50%? this sounds awfully inexact for the mighty microsoft.


Thanks.
 
I've found with ht enabled pc's 2 processes doesn't work at the same speed but you will do a few more work units a day with 2 processes than you will running just one I do 13 a day with a 2.4 p4 with 2 processes and only 8 or 9 with just one process.

It's kinda because windows views the processors as two logical processors (almost but not quite, I had this explained to me really well a while ago but I can't find the thread). The numbers you see in your task manager won't reflect what is really going on (unless you're at 0 or 100% usage). But, if you have two logical processors and 1 program using all the resources it can get it's logical that only 50% of the processing resources are being used. Am I just confusing you now? I'm confusing myself, at least 😕


Edit: here's the link, read towards the bottom.

Hi 0x0, I have a Toshiba notebook with a 2.8GHz P4 w/HT. I have SetiDriver with 4 WU's loaded and one copy of SetiSpy running. The % Complete is for the WU that has the highest % completed. You will notice that when one finishes that the number does not drop back to 0%, rather somewhere between that and 100%, based on where the 2nd WU is in it's cycle.
 
Hello Richard,

I'm running the same system. It is my primary workstation and gets used quite heavily 24/7 in addition to running Seti. 🙂

Over a long period of time my system has averaged 17.61 WUs @ day with an Average CPU Time of 2 Hours 41 Minutes. I have a second system identical except it has a 2.8 GHz HT CPU. It is not used very much and has averaged 16.23 WUs @ day.

I wish there was a way to crunch 1 WU with all of the horsepower available but as already explained that is not possible with these HT systems. I still consider my 3.2 GHz HT machine my fastest for if you divide the 17.61 WUs @ day into 24 hours you get an Average CPU Time of 1 Hour 21.8 Minutes. 😀

My 1.7 GHz Centrino does 13.38 WUs @ day but has an Average CPU Time of 1 Hour 47 Minutes and shows up as the fastest machine in my SetiQueue.

You and I know differently ... don't we? 😛 😀


BTW, we sure would like to have you join our Seti Team. We call it "TeAm". That is sort of shorthand for "TeAm AnandTech SETI".

This is great news. I have everything bought to put together a nice P4 2.6C@3.3 rig to run Exchange and of course, SETI! 14-15 more WUs a day is sounding pretty darn good. 🙂
