Days later I met a stranger in the office who introduced himself as an outsourced IT expert hired to help figure out why all the office and warehouse computers had slowd down so much. It turns out (of course) that my friend had snuck around at night and put SETI on every computer in the building.

How did the computers slow down to a crawl if SETI only uses spare time and uses a lower priority?

All this farm talk makes me think it would be great if someone would post a design for building a solar power system specifically for powering a seti farm. If there is expertise out there, I for one would like to see some ideas.

Now this idea deserves a whole thread all by itself. I like it.

I think that is probably just an excuse and not the cause of any slowdown. Could be wrong but that doesn't seem to make any sense at all.

I really dont think its the cost of the computers. Ebay is a great source of bits. I have been to the local rubbish tip and got loads of bits that work for free. Hard disks, ram, powersuplies etc. Having 10 or 15 computers is not costly except if you want the dual core cpu's etc. Linux is almost free so an operating system is not the cost (win98 & nt4 can also cost not a lot).

As we all know its the cost of powering these things 24*7. At the moment they are drawing about 1.5kw.

I guess like a lot of IT people who work in large departments and see 100+ machines switched on all hrs doing nothing, I wish they could run boinc out of office hrs. But even mentioning the idea sends most managers into panic.

Wonder how long a clockwork computer would run without a rewind.....

Everyone has a right to their own opinions, and here's mine. If all IT pros could somehow wrangle boinc onto every machine under their control (with the approval of management, of course) I would view that as a good thing. This includes governments, corporations, small companies, sole proprietorships, S Corps, etc.

The key phrase being "with the approval of management...."

I agree wholeheartedly.

Tick.
Seti wasn't what slowed the computers down.
I have run the current BOINC version only on my own computers & am able to rip CDs, convert the odd one to MP3, burn discs, surf the net, stuff around with the odd databse with no effect on performance at all.

In my previous job i had Seti Classic running on 2 of the 10 computers there & there was no effect on their performance at all (couldn't run it on the other 8 as they ran a DOS programme under Windows & so Seti would never have had a chance to run).
When they were doing nothing (or bugger all- which was about 85% of the time) Seti would run. When they had to do work, Seti would relinquish all CPU time. No problems at all.

I could run optimised science apps and reduce runtimes, but I run vanilla project science applications on (personal) principle, and not all projects have optimised apps anyway. So that wouldn't make much difference.
(snip)
Not a personal attack on you, just explaining why I'm not rushing round installing optimised code everywhere :)

I run only open-source projects for two reasons.

First, I believe that public projects benefit from users by using community resources. Thus, they should make sure that users can benefit from the projects and release the source for the science. Also, users will be able to verify that the science done is truly done for public good.

Second, I believe that open source software can and will be optimized, and that's one of the open source advantages. Therefore, I have no concerns running optimized boinc client and seti science app.

For the projects which decided to keep their science closed source, bad luck for them: I no longer consider running them, and as you can see from my RAC, I do quite a bit of science.

Im in the same boat. I have even had to add breakers to my main service panel at my home. Falcon I like your setup I think I asked you once before. How do you set up all your computers to show up with all your cpus and stuff? I am networked as single useres on all computers in case of hak attack they could only access 1 computer not entire network.

Nothing fancy, all is still entered and updated manually (easy 30 Second job, since I usually only shutdown everything when I leave for a longer time).

I'm sure it would be quite easy to create a dynamic Page, based on available Tools (I've used remote Host Monitoring including Health status in the past, one could even present each System's Uptime or alike).
But since I'm on DSL and treat it like a Dial-Up line, the Network isn't connected to the Internet for ~50% of the time, so a permanent/real-time Update of that little Page wouldn't work. It's just easier for me to quickly update the Page once a while, not worth the hassle otherwise :)

Only my Main machine has Internet and Firewall, the Net behind it is "Green" (only the one other remaining Windows box has its own Firewall as well). The Linux Boxes and the remaining SGI are remote controlled with SSH and standard password protected... Remote File access is restricted to the TMP and BOINC working spaces.

It would be neet to see a thread explaining how you do this falcon fly. I own all my computers not work computers. Have to say this to other posters about people using computers that dont belong to them. I own mine at home. Crazy thing BOINC Seti@home makes you want to buy more computing power than nasa.

Nope, he hasn't. His networking setup is creating new host IDs every time a host is booted.

He has over hundred PCs, though...

Hm, that would be more or less a HTML lesson, these are available (much better than I could explain) elsewhere already (SelfHTML for example).

I saw a news story not long ago during the time they were talking about how much it would or will cost to heat homes this winter due to the hurricanes. It showed houses using Solar Panels that were smaller then when they 1st came out. These panels were place on the roof to where they got the most sunlight. Based on the news reporters story these new panels are alot better then when htey 1st came out and produce more power then most 4 room houses needed. In fact they show the meters spinning backwards. The power company was getting "free" power to the power grid. The story went on to say that it would "pay for itself" in about 10 years or less. There were no batteries in this system. At night they used power from the power grid. During the day (even on cloudy ones there was enough power to run the house and at time spin the meter backwards.

Just thought this was kool. However, this news story was taken somewhere out in the middle western part of the states.

very impressive...though not as energy efficient as they could be; due to the materials that they are made of. however it makes up for it in start up costs...

the biggest issue in cost is getting the turbines attached to the national grid which can cost upwards of $30k per turbine...that's where most of the costs are
