You don't need to turn off HT in the BIOS is you can't. The 50% you see doesn't matter, as the CPU is really running close to 100% when you have 2 instances running.

If i run 2 processes of rosetta without changing the bios settings of the machine i will only run with 50% cpu power.. I need to turn of hyperthreading in the bios in that case. I wonder how Ubuntu 7.1 Server would react to such setting?

For the other Xeon machines i can not change that since those servers are in a production enviroment... But it would be nice to test it and see if it makes any difference..[/quote]

As I have pointed out to you, your xeon seems to be slower than my Core 2 Duo @3.2GHz.
I think your Xeon have HT on, but that would not help at all, since it only have 2 actual cores anyways.
The celeron you have is using the "Core 2" architecture, therefore they are actually pretty good.

I have a super old Pentium III 400MHz, would it be able to complete any workunits before the deadline?

You can google BOINCpe, which can be run on a flash drive.
I have several machines running it, and not a problem at all.
I can also provide you with motherboards. I sell them and know where to get it cheap.

For now, I am still working the issue out with my ISP situation.
I will keep you posted when I am sure that internet would not be interrupted on my BOINC machines. For now, I am still crunching, but smaller amount.

Hi, I tried to contact you 3 times!!! I was trying to ask what organization you want me to run BOINC for. I did not assume you are from Rosetta@home because I don't know that. Maybe now I know. But you can be on another BOINC group too.
Email me and tell me the organization you want me to run under.

Again, this is a misunderstanding, as I tried to contact you via email (your paypal email), and so far no direct reply from you.

The machine is already ready to crunch away!!!

For those that are still skeptics, heck i am even willing to crunch for 1 week free for you to show that this is certainly NOT scam. I am also an ebay seller, I have well over 500 feedbacks. for those that care, http://myworld.ebay.com/careaboutyou
buyer beware, I donated to chungenhung over 48 hours ago. I haven't heard from him yet. I will keep everyone posted.

Sounds like a good plan if you can get all the tax breaks too.

How much would you expect if someone wanted you to dedicate a computer to ClimatePrediction which take a few months.

I would still suggest the stated $30 per month for the quad core.

I do have a couple of PS3s. I have more PC because PCs have more projects to work on.
If you were buying computers just for grid computing, the 40GB version of the Play Station 3 would seem to be the most efficient, but unfortunately not all projects have PS3 clients written for them.

I've read that the 40GB PS3 uses about 140 Watts for about 25 GFlops of output.

The older PS3s use about 200 Watts for the same output.

Do you have a translation?
I can't read german, and tried but failed.

In addition, you said you use BoincView to monitor the system, how can you do that when BOINCPE asssigns different IP address each time? Also, the computer name is ALL the same?

check this forum for further info

Anyone that use diskless please post here.
Share how you best manage your computers.
Such as Network boot, USB boot, or CD boot, or whatever method you use.

Also, it would really help if you provide a way to share what you have setup and make the files available or at least let us know how to set it up.

I am sure there are a lot of us with more than 2 computers and are trying to find a more efficient way to run BOINC.

I have a special interest here using BOINCpe. I see that there is a tutorial showing how to Boot it over the network, but it is in german on the BOINCpe site. One question that I would like to ask is that is there a way to make the BOINCpe set up a DIFFERENT computer name for each machine? Perhaps using the MAC address then determine the computer name to be assigned. Ex. If MAC address is 44-23-15-n3-43 then assign a name of PC3.

I am just starting this, and it will take a GOOD WHILE.
But your idea is certainly great.

What does everyone think of:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=110202461065&ssPageName=STRK:MESO:IT&ih=001

I have started this back in the summer, and I need to gain more supporters.

Basically, you make a certain donation, and I will "crunch numbers" under your account. So you get the credits/points.

Recently, Dr. David Anderson (Director of BOINC and SETI@Home) approved this.

We all know that the U.S have cheap Computers and electricity compared to other countries. And living in a capitalist

country, I think this is the way to go.

Here, I am trying to build a folding farm to crunch numbers.

These are the estimated costs for crunching for one month on a quad core machine:
$0.104 (avg cost per KwH for 2006) x 24 hrs x 30 days x 0.2 KwH (200 Watts) = $14.976

Average cost per KiloWatt is based on Average Retail Price from the EIA
http://www.eia.doe.gov/cneaf/electricity/epa/epat7p4.html

There are also additional costs, such as hardware, AC during the summer, among others.
In addition, I have Dual core machines too, which will cost more for electricity.

So, I've sort of came up with a donation schedule, if you have a opinion, please be glad to let me know.
$30 per month for Core 2 Quad @ 3.0GHz
$15 per month for Core 2 Duo @3.0GHz (I will be very disadvantaged here, but since Dual core only pump out about half as

much points as a quad anyways.

So, if it costs you a lot of money to keep up with your "old" machines (say Athlon XP or Pentium 4), why not put the

resources together and I will crunch for you.

Again, I've started this since summer, and have purchased several Quad and Dual core computers.
I hope to keep this up. If I see there is a steady flow of sponsors, I will buy more machines.
For now, I am putting all the money that I receive into buying more computers. I am absorbing all the electricity costs for

now.

If you have any questions, please email me at forfleabay@gmail.com

Also, please take a look at the ebay listing. I put it there to get some attention, but it was too expensive with ebay

fees.... So I am posting here.

REMEMBER, even if you don't donate, my computers will still be "crunching". But if you do sponsor, I will be able to grow

the farm.

Here are my stats for BOINC (WCG and SETI):
http://boincstats.boincstats.com/stats/user_graph.php?pr=wcg&id=43317

Here are my stats for Folding@Home:
http://fah-web.stanford.edu/cgi-bin/main.py?qtype=userpage&username=chungenhung

For those that think this is a scam, it is not. I have been a cruncher since 2004. In addition, you can check my ebay ratings.

For those that have a "old" computer or simply parts, I am will to take them and in exchange, offer you "crunching time" from my grid. I see this as reusing parts that you don't need, or otherwise would cause you more trouble.
