An interesting point comes to mind: It may not be worth running BOINC on old computers because the science completed by an old 450MHz desktop may not outweigh the expenditure of electricity and thus fossil fuels. Is the tiny amount of science crunched by old computers worth the extra pollution?

What do people think about this?

As long as the WU is completed before the WU's deadline the computer will contribute to the project. The CO2 produced by the process of generating the electricity to power that computer, is another issue. I suggest buying some solar panels or wind turbine, connecting a battery and then plugging in the computer. This will produce free carbon neutral power for the computer, although this is expensive.

It would probably be cheaper to just upgrade to a new faster computer. Even if you shut it down when you're not using it, it will probably do more science and take less electricity than an old 450mhz crunching all day.

Well I would say, it depends on what other use this machine still would have. If you are running a 450 MHz only for crunching, I would suggest to shut it down.
If the PC is running anway, why not crunching.
About the power usage: An AMD K6-2 450 is rated with 18 W, an AMD 64x2 4400+ with 89 W. This is only the CPU tho, the rest from the system uses probably nearly the same ammout. Also, the AMD x2 probably cruches 10 times faster or even more.

Great point. More generally, at what RAC does a dedicated host become environmentally justifiable? Maximizing a dedicated host's RAC/watt can involve more than getting the most power-efficient CPU - unplugging the monitor, keyboard, mouse and video card (assuming the host isn't being used) will save a good amount of energy.

And though I haven't experimented with it yet, BOINCpe supposedly makes for more energy efficient computing because it uses a CD-ROM drive instead of the typical hard disk configuration. I would be interested to know the average energy savings from switching to CD-ROM based BOINCpe. The only way I can think of to easily measure the difference is with a power meter, something like a P3 P4400 Kill A Watt Electric Power Usage Monitor.

it's an issue for me. Most of my computers are remotes, but the ones here are all on 24/7 apart from one. I don't think it's such an issue in France and some other countries because the majority of the electricity is nuclear and so there's no CO2 cost.

Obviously there's a cost and a benefit to having them on, but IMO if it's slow and wouldn't otherwise be on, turn it off. Of course they should all be running BOINC while they're on though!

There are a lot of things you can do to make computers more efficient though - two of my computers here now run BOINC from compactflash cards - the adapters were about £6 each and the 512MB cards are less than that each. I set BOINC to write to disk at most once every 5 mins and this way the HDs can spin down as BOINC isn't writing to the HD any more.

I've undervolted my laptop which has lots of benefits such as longer battery life and it runs a *lot* cooler.

Use smaller, high-efficiency PSUs as they're more efficient when near their power limit - high efficency ones i use are Seasonic and QTechnology ones.

LCD monitors must have made a big difference over the last few years too...

For me, the time of year has an effect. During the winter, I'll run some old slow PCs as crunchers, with the added bonus that they heat my house. But they're getting switched off around now as we get into spring.

That's a good point - if the heating would otherwise be on then you might as well use computers to produce the heat! I was planning on getting a few old rigs running for this purpose through the winter but the memory costs weren't ideal...

there's another point here too - how much energy will be saved by the creation of a drug that has a major impact on a major disease - it'd be millions of times more energy saved that expended by the extra computer. Or from the ability to determine protein structure without the energetic expenditure of a lab for however long it takes... it could be considered an energetic investment i guess.

Matt, yeah, I gotta think that the energy used by a sub 1000MHz computer is fairly high compared to the science. Not much of a point to crunch with based on power costs & pollution.

Overall, computers save the world FROM pollution and wasted resources. Computers do the work that it used to take 20 people to accomplish (OK, I just made that up). So the freeing up of those resources makes us a lot more productive. Just think... 20 people need 20 desks and 20 light bulbs, etc.

If you're running 8 400Mhz machines and can afford to replace them with a single dual core 3-4Ghz cpu, then you'll be spending less on electricity with the single new system.

Contributing to Rosetta or Boinc projects in general shouldn't be limited to just those of us with faster machines. If the Carbon Dioxide produced from electrical production is considered a big deal - then encourage everyone to plant a few trees for every computer they use.

What do people think about this?

We need more Nuclear Power Plants. After all, at it's inception, weren't the predictions that by now we'd all get nearly FREE electricity????

Then we could run whatever we want.

same goes for toll roads and bridges. Those tolls were supposed to stop after they were paid for???

at its inception the thought was to recycle the fuel which was done away with in the 70s.......and security which costs millions was cost free at the time because it was non-existent.. just 2 of many i bet they did not figure in at the time

A number of high profile "anti-nuclear" environmentalists have actually come around to the idea that nuclear is the lesser of a number of evils, and that a new generation of nuclear plants is required to offset the energy gap. I watched a lecture by Professor Richard Muller of Berkeley on this subject recently.

What is really sad is that we still have to rely on "dirty" nuclear fission reactors. We are not yet able to generate useful quantities of energy from nuclear fusion.

What I regard as criminal negligence is that after the completion of the work at JET, the involved governments agreed to the funding of the next generation of fusion research plants. This would hopefully result in a workable prototype commercial reactor for global use. With money and will available, the squabble came down to where it should be built - unbelievable. Years wasted arguing over insignificant detail.

just wait until wind and wave energy get more efficenet
i read that russia is working on a big wave energy project
over here in my little neck of the woods i got 4 nukes, 2 old 70s era and 2 late 80s units, 4 wind turbines plus one other in the harbor. More wind turbine is planned for later on. The city is demonstrating solar power and we have the 2 incinerators doing co generation as well. Also have one gas turbine plant that runs one unit all the time and alternates with the other one or runs both if their is heavy demand.

We have no nukes here. Many of the large wind turbines you see around the world are made here, many are installed in the West of the country here, there are also many sited offshore. There is a large farm just offshore from Copenhagen, in the Øresund between Denmark and Sweden. The toruists go to look at it - can't imagine why, they just go round and round.

Combined heat and power with district heating is pretty much the norm here, even small towns have district heating with co-generation. Waste incinerators typically are connected to district heating networks.

In Helsingør, we have experimented with producing Biogas from household organic waste, (we have seperate refuse bin for this). The plant basically works, but the energy it produces is more expensive then simply burning the organics in the regular incinerators, so for now it is only a research station.

Wave power is impractical apart from a few select locations on the West coast.

A good number of houses have solar water heating, and photovoltaic arrays are appearing on a few houses, although the payback period is very long.

we have bioethanol in our road fuel at varying percentages depending on the fuel company.

If I throw the old computer away I will be adding to the landfill. I know they can be recycled, but the closest place to me is 80 miles away and they charge money ($20-$30) for recycling. The landfill is free and 10 miles away. I don't begrudge my 486 its 60 watts. As long as it works it stays out of the landfill.

lil ol belgium has i think 2 other reactors for power generation plus these 4 here. there are a few other gas turbine plants that are more modern than this eye sore by me. electrabel is our electricity provider. wind turbines are not that popular yet due to cost and location problems. as for food waste, that is sent to a food waste compost center to be treated and bagged. our area is to spread out and the water table to close to the surface to run any sort of steam network, though with the nuke center and the incinerator and the gas plant here you would think that wouldn't be a problem. Also i wondered if the refineries and their flames could be harnessed for making steam. The heat off some of the chemical plants flames here is amazing. The color is bright orange when they run. They muffle the sound, but still. Only problem I see is that this is not a constant source of heat, it comes and goes alot. Our local swiming pool center is solar heating the water, but the electricity demand is to great for solar power there. most houses here use natural gas or stove fuel in the winter to heat the house and in summer just open the windows at night and then close them and the shades/curtains in the winter to keep cool. my little computer does a good job of keeping the front room warmer, not to mention the deep freeze warms things up a bit and the refrigerator as well.

Personally, I think it comes down to an individual's preference. What are you willing to sacrifice? Will you use your 3 GHz machine for gaming online and expend all that electricity for mere entertainment?

If everybody obtained the most efficient computer for crunching and trashed their old computers, just think of the resources needed for production and the waste in the old boxes. The initial investment has already been made for the sub-GHz boxes out there, so if it can contribute in a timely manner, so be it. Now, my parent's Apple IIGS running at 2.6 MHz might be pushing it... But where is the line drawn? It's a personal choice.

Although my two 266 MHz boxes will probably be only running at night, utilities hate high demand during the day in the summer.

(p.s. to MattDavis - I cannot stop thinking about Team America when I see your name, think "Matt Damon"... HA!!! oh what a great flick...)

I tend to think of it this way.
My PIII 1Ghz boxes make about 100c/day. My quad core Xeon3210@3.2GHz makes about 5000! That's 50!! P3's.
The xeon draws around 360 watts w/o the screen turned on, but it has a 8800GTS video card and is oc'd about 65%. I'm guessing it would draw around half w/o oc and video card.
The PIII's each draw around 45 watts.

Multiply 45w times 50 and compare that to to 360w, that's 2250w vs. 360w. Thats a HUGE difference. Both for the pollution AND the (at least my) wallet!

I have free electricity at the office, but the older boxes take up a lot of room and make an awful lot of noice! Just not worth it any more.
Now that it's warming up outside I'm pulling 6 PIIIs sub 1GZ, and I won't look back!

Hi student,

I just ran across your post while looking for some BOINCpe stuff.

I've been playing with BOINCpe for a little while (on and off). Right now I have 2 boxes (soon to be 3) running on it. Here is the thread for our board:

http://amdusers.com/forum/showthread.php?t=3760

No professional testers, just poking around. It is an interesting platform.

Right now I have both boxes booting from 'Flash Drives' (even less power draw than a CD-rom). Box #2 has an ASUS micro ATX MB, with onboard video, lan, No drives, 1 gig ram and a X2 4200(89w) with no OC. It runs at 100 watts at 100% cpu usage. This is the only 89w cpu I have. Everything else is 65w (4800's and 5200's).

I have 5 of these boxes right now, and plan on running BOINCpe on all of them.

EDIT: I have a Kill-a Watt....

Only problem is there's no paging file when you run like this so you need to make sure you're not going to run out of RAM. As Bender10 does, I have a few machines (including my MCE2005 mediacentre) running on compactflash which is great and really easy (as long as you're not running the enhanced write filter which is a bit more involved).

I believe one of the biggest differences can be made by getting a high efficiency PSU that isn't too big for the machine (they're more efficient when running near capacity)- I tend to use Seasonic S12 series which are great - very quiet.

Also, decent thermal compound, and keeping the machine cool will keep temps down and therefore reduce resistance. Other options are undervolting - using bios/rmclock etc...

If you need air-con on then that adds a huge amount of power required, but if you need heating on, then the computer might as well be doing something useful with the energy first.

If you run 'straight' BOINCpe, there is no writing to the 'Flash Drive'. The OS is loaded onto a 'RamDrive'. So, no writes to the 'Flash' which may shorten the life of the 'Flash', unless you program a backup to the 'Flash'.

I have run the following Projects on BOINCpe so far, with a 256 'RamDrive' (this leaves me a little over 512MB free ram for crunching) with no memory issues (yeti).

And since BOINC likes 128 MB ram or better, This works good. I am toying with going up to 1.5 or 2 gig of ram for my BOINCpe boxes


PROJECTS:
BOINC (about 12 different projects), D2OL, TSC and Pi Segment.

With D2Ol and TSC, I typically run with about 100-200 wu's on the 'RamDrive' each. I have yet to use more than 50-70 MB of the 'RamDrive' while running most projects. Execpt for BURP, That takes up a lot of space (>35 MB)...

NOTE: I just finished running 5 days worth of Proteins wu's from a BOINCpe box...

A previous post mentioned use of a slower machine wasn't germane as the point of it all is to finish the work units. If this can be done, then why not... At the same time it's worth mentioning that when Distributed Processing was originally envisioned, it was to make use of unused cpu cycles while doing regular work on our PC's. It wasn't to "Crunch" as an end in itself. To do so is a waste of electricity and a harm to the environment.

You're absolutely right regarding computers that are on anyway - it's beneficial for them to be crunching for the small increase in power consumption, although the mitigations listed can all be applied to these to reduce their power consumption. However, there are lots of people with dedicated 'crunchers' - are these environmentally damaging? I can't decide (and I'm heavily into environmental issues and sustainability!). In the short run, they are obviously polluting, although if they weren't on then maybe the bakerlab would have to employ their own machines for the purposes, with air con etc.

IMO it's more complicated than that though. A simple example is that if the bakerlab produces a successful carbon sequesting enzyme then that would almost certainly massively overcompensate for the extra energy utilised by the dedicated computers running rosetta. I guess that depends on whether the results would have been as good with all those crunchers turned off. Another example is that I run some machines overnight that wouldn't otherwise be on. My understanding is that there is an excess of electricity available at night due to the reduced demand (my electricity costs around 3.5p between 12am and 7am, against ~14p for the rest of the day!). If the computers are producing heat, then, assuming the area will be heated anyway, then they might as well be on. If you consider the environmental costs of a single car journey, or the costs of treating one person with a disease such as cancer, the environmental costs there can be quite high...

For now I'm leaving mine on (no dedicated crunchers - they all have a purpose - some are just remotes of family/friends etc, so they're only on when in use and and at home i've got mediacentres/server/main PC). I consider rosetta as energy use rather than energy waste. I reduce my power consumption as much as i can practically in every other way though (efficient car, low energy light bulbs, high efficiency psus, recycling, careful use of water etc), and if i needed air-con at the same time i wouldn't run the pcs 24/7. However, I can't see any environmental justification for running crunchers that run seti or OGM etc...

just a simple point here.

i do 24/7 crunch to try and help this project along and hopefully soon they will get to cancer which is the main reason i came to this project.

atm its cold here in northern europe so by leaving my computer on and its running about 53C cpu plus whatever comes off the powersupply i can keep the temp in the front room at shirt sleeve level, maybe a little cooler, so i dont freeze and there is no need for petrol heat. (no electric heat here and the gas stove is to inefficient to use)

i keep all the lights off during the day when i am home to conserve energy and i don't need them either. if i need a light here by the computer i use one of the little desktop halogen lamps. not much draw there. the only other electricity use outside of keeping food cold and frozen is the tv and vcr (dvr is to expensive for me at the moment).

so i serve a good cause and i keep the front room comfortable and use about 160 watts of electricity in the process. not a bad trade off.

hehe since when Belgium is northern europe ? ;) I got 25° here in "real" norther Europe ^^

I personaly dont run my PCs for crunching only - they do crunch when doing other stuff, but thats it. The question, when a rig is insufficient is quite hard to answer i think. When it comes to work done compared to electricity used, no actualy home PC can beat any of those super cluster machines, f.e... So it would be more efficient to donate for such a machine and let it run Rosetta then to build cruchers at home.

It would be interesting, how high the power consumption per year is from those ppl, who run some dedicated cruchers at home (in kwh/year). Ive heard some ppl who live in a small appartement alone do use up to 9500 kwh/year, which is pretty shocking to me. Last year we hit about 5000 kwh (small house, 3 persons, 3 PCs - not running 24/7 tho, electric sauna and in the winter car engines get heaten with electricity aswell) - which is already too much for me, trying to go down to near 4000 kwh if possible.

lmao, ok mainland europe, you guys up there in ice world have the true north.
man your lucky at 25c its only 16-17c here at the moment with lots of rain showers and clouds. dang brits are to blame.
well this machine 100% when idle and about 70% when active in crunching RAH.
I use it for email and web browsing and an occasional Age of Empires game, so lots of spare cpu cycles to spare when not gaming.

i'll have to look at my actual power draw on this power supply and then figure out how to put that into kwh/year. thats for later.

Hehe, why did i spoke it out loud? Today I got hit with bad weather also :) Not raining yet, but i bet any money it will soon ^^

Same about my PCs, I hardly ever go on 100% CPU load without Boinc, only for gaiming and for compressing some videos, which is like <15 hours/week. Most of the time im using it to browse, chat or work on our webpage. I could use the cool n´quiet function instead of crunching, but given that i have a highend GPU which pulls a lot of power even when idle, I think doing some BOINC compared to those 20 watts more is a good deal.

Talk about Games&BOINC:
What I experianced btw is, that some prjocts are rather instable when they have to share CPU power with other applications then other. I did run Rosetta while playing FEAR most of the time, although it only made some progress during the map switches, but atleast it didnt crash. Later i run a SAP model and played some Simcity 4, after i ended the game i saw, the model had crashed - since then i always shut down BOINC before i hit any game.
Another weird thing is: My brother does play a lot of DiabloII, when BOINC is turned off , Diablo uses 100% CPU power, when he leaves it on, BOINC manages to grab 60% CPU power, without slowing the performance of the game - weird stuff :p

well with age of empires i can run a game and not crash any work units and manage a reasonable game performance and boinc performance. the settings are for boinc to use 70% cpu when in use. So that leaves 30% for gaming and its not that cpu or graphics intensive if you set it right. I had to dull the graphics down a bit because the characters were moving to slow due to the performance of the graphics card. If I get into a marine battle then I have to pause boinc and then continue playing and resume boinc when done.

with a amd 2800+ and a radeon 9600 i don't use that much electricity.
deep freezers and refrigerators use more. cool and quiet is a nice feature of msi boards, but my system does not get hot enough to benefit from that program. its more of a monitoring program for cpu temp.

As to Gameing i run 2 WUs my Music in the background and 2 Clients of EVE-online. I get no errors so far and no lag on the game. As to running the machines 24-7 if you are worried about the polution factor use Compact florescents where ytou can in your house. I prefer the the true Sunlight bulbs to the others but 23 watts instead of 100 is a big saveings per bulb.

The games should run fine since the the BOINC project should stop crunching when another program demands the CPU time, which being a game will be at a higher priority level than 'idle' assuming the project has set the priorities correctly.

The only thing you will notice is a slight delay as memory gets retaken. Though with CIV or AOE where there can be low level cpu usage times and are not so taxing till later in the games you will see boinc run.
That is if you have the memory set to a level of 'in use' where it can run.
