Greetings from Germany

Sir Ulli

Imhell = Intel

About to install the AMD version on my Sempron 3100, hopefully stop Wiz from getting away .

 

[petrusbroder]

Installed the optimized version on all my comps crunching seti@home.
Now we will see if there will be an increase ...

BTW: I noticed after 1 - 2 hours that CoreTemp reports 1 - 2ºC higher temps for my cores - time to switch all CPS/HSF to ICD7 ...

I need to get me a tube of that. I know microcenter in rockville, md has it for $10 a tube.
oh... and I've been switching my systems to water

On what CPUs?

 

[bryanW1995]

all of mine run 1-2c hotter now, but no big deal. it's only summer in south texas...we're used to the heat.

peter, judging by my experience on the A64 3200+ laptop, you should be VERY happy with your results.

 

[petrusbroder]

The decrease in crunching time is quite awesome:
These numbers are for one computer (AMD Athlon 64 X2 Dual Core Processor 5000+ @ 3000 MHz, 2048MByte RAM)

Standard application:
CPU-time ______ credits _______ Task-ID
(seconds) _____ (granted)
13 677 ________ 54.11 _______ 831 655 388
13 541 ________ 54.11 _______ 831 655 389
13 839 ________ 54.11 _______ 831 655 404

Optimized application:
CPU-time ______ credits
(seconds) _____ (granted) _______ Task-ID
_6 832 ________ 54.11 _______ 831 655 408
_6 674 ________ 54.11 _______ 831 655 406
_6 805 ________ 54.11 _______ 831 655 391
_6 766 ________ 54.11 _______ 831 655 375

As you can see from the Task-ID the tasks come from the same tape and have been prepared in the same way. My other computers show a very similar pattern: slightly less than half the time needed for crunching.

The temperatures are - on the average - some 1.8 - 2.1 ºC higher than before - and that is for all my AMD-processors.

[somewhat OT]
I am really happy with the ICD7-compound: the 2 comps which use that compound run 3 -4 ºC cooler than the one comp with the same processor, OC'ed to the same speed, using the same HSF. I will switch over to ICD7 as soon as I have the time (it takes some 10 minutes for each cruncher - disassembling, cleaning the HSF and CPU, applying the ICD7, assembling) and I need to do it for more than 20 comps ...)
[/somewhat OT]

I really like this optimized app! Probably my production and RAC will double in a week or so. :thumbsup: :sun:

Edit: added the somewhat-OT paragraph.

BTW, dajeepster, I have pulled more to the right, these are no others on the road, so passing me should not be any problem ...
Yeah, water cooling is better than air. I really would like to have more comps on water - but the price differential is way to high for more than 20 comps - and then the maintenance once every 6 - 9 months - for all my systems - [Petrus shudders].
Checking and cleaning out an air cooled comps takes less than three minutes ...

 

[bryanW1995]

you need to set up a custom liquid cooling rig for all of your rigs in the basement... one big loop for all of them! um, you do all the setup and legwork, but make sure to tell everyone that you got the idea here first!

Well, I am sorry, but you were not first. When we designed the heating in this house (some 1½ years ago) we were seriously considering to add a loop from the computers to the heating system (essentially having the comps in parallel with two pumps in parallel [redundancy, you know]).
The maths is not too bad (20 comps with an output of 80 - 130 W = 2000W) but we soon realized that the hot air from the PSUs would not be used. The cost and the trouble of keeping the system waterproof and air free (with so many connections) was just too much.
Now I extract all the hot air from the computer room, the kitchen, the bathrooms and the bedrooms, to a heat exchanger in the attic, which heats the incoming air. The net effect is some 7 500 - 9 000 W, (the efficiency is 84%). In summer the heat exchanger is bypassed and we have some very comfy home ... from September to January and from March to May the comps, all the other electronics in our home, the bathrooms and the kitchen are the sole heating in the house. Thats why I am not whining about the cost of electrical power - it is used for several purposes very efficiently: we (6 teenagers, 2 adults, 3 cats in a house of 370 square meters = approx. 4000 square feet, 24 computers) use a total 24 000 kWh a year...)

Not everybody has a computer heated home ... I am quite proud about the system.

A conversation with my wife mid-february:
"Petrus it is somewhat cold indoors!"
"Ok, dear, I'll get one more computer tomorrow ..."
"Oh, ... can't you build one tonight? It is - 22ºC outside!"
"Are you sure? I have some parts in the computer room and it will take an hour or two ... ."
"I'll be so nice and warm for you ... :heart: "

 

[Assimilator1]

LMAO! ,awesome setup you have & a great deal with the wife too!
Though I don't quite get this

What happens to your hot air then? heats the water?

Hmm, eggs in one basket springs to mind .

No, it just disappears out of the house - because the house is warm enough and the hotwater is generated through a deep-well heat exchanger...

 

[bryanW1995]

my x3350 is up to #40 in the world:

and dajeepster is up to # 23

 

[Assimilator1]

Awesome! .

 

[Wiz]

This is kind of strange.

BOINC says this about my system:
5/6/2008 3:32:04 PM||Processor features: fpu tsc sse sse2 mmx

While CPUZ says:
Instructions: MMX, SSE, SSE2, SSE3, x86-64

It's a P4 630 Prescott @ 3ghz
What's the deal?

 

[petrusbroder]

CPU-Z is correct. I am not so sure if BOINC can recognize SSE3 at all.
Anyhow, I tried the SSE3-optimized app on a AMD CPU wich according to BOINC "only" had SSE2 but which according to CPU-z also had SSE3 and worked perfectly well.
The devs of the optimized version also tell to use CPU-z.
Just go ahead! Try it, it will certainly crunch faster!

 

[Philippart]

boinc doesn't recognize anything higher than sse2

Exactly. BOINC's way behind on these issues.

No single project even uses it so far on the official apps. SSE is only used by some projects like Einstein or SETI.

 

[Wiz]

Cool - thanks guys!

 

[bryanW1995]

yeah it makes no sense to me that we need a special app to take advantage of sse etc. its not like sse snuck up on them...

 

[Assimilator1]

lol

Hey Wiz
Read my PM?

 

[Wiz]

only just,

heh - didn't know I was doing that well - kinda distracted in RL atm, nothing bad, just busy.
Not too busy to install the latest seti app on a few boxes tho

 

[SirUlli]

i had time so i look at my Quads

[bryanW1995]

TAT says that's on a pentium M but it looks like a quad...???

 

[petrusbroder]

I have been looking at my numbers ...

Seti@home production for one week before and after I switched to the optimized app: no comp added, no comps withdrawn, all was just exactly during the comparison:

with standard application: 4 727 credits in 7 days
with optimized application: 7 041 credits in 7 days

I have not switched all my comps to the optimized app because I do not have access to them all just now. But I certainly will do that as soon as I can - four more crunchers with doubled seti-points ...
