I'm surprised no one has mentioned it, but hasn't anyone thought of the extra power required to keep your CPU running at 100% 24/7??? On my micro server I noticed pretty much a 10watt difference running iTunes (not at 100% CPU)

My cpu uses an extra 25w at 100% than it does at idle so not worth being bothered about.
A quick rough calc means that will cost me about £28 extra per year.

I was blasting my GPU for months mining bitcoins and didn't notice much difference at all in my bills, so I'm not fussed about doing this either. Plus I can have the heating on a bit less  ;D

I did see an argument the other day regarding the cost of power used in  Distro.Comp. projects, and that if you were to say everyone would pay £30-50 a year running their machines for a project, what that would equate to if people just donated that much money to the scientific community. It's an interesting thought that made me pause.

I decided there's no harm in running it at uni seeing as for the most part machines are left running 24/7 anyway, and the university haemorrages money like no ones business for minor things.

As clocked says about heating, it's actually keeping the office quite nice and warm too. Now we have some critters in tanks that's handy. Might have to reconsider in the hottest months of the year though.


Serious

If there is a need for heating then there is little point in not using it to do something. Otherwise it is probably better to switch off the computer to save power.

It's currently keeping my megasoma mars grub nice and toasty.

Milkyway @ home is wayyyyyyyyyyyy more generous with its credits than Rosetta @ home was/is!

I think you're right, looking at the stats I don't know how I've got massively more credit than you guys:

Must be that i'm running 24x7 and you guys not so much?

Well I spent a month on Rosetta. At the start of this week I told Boinc to not download any more Rosetta tasks, and also joined Milkway. In the week I've been in Milkyway I've almost got the same amount of cresit as I got over a month on Rosetta!

So I think the main reason you've got so much compared to me, is that I was getting 1/4 the credit for the last month! Hopefully it'll shoot up now over the coming weeks.

I took a look at the computer specs too and I think my processor being a bit newer is probably helping, but yours and DEViANCE's should be pretty even as you're both running similar dual cores.
