I just happen to notice when the MW v1.02 WUs are running, power draw at the wall goes up a lot on my PC (GPU is an HD 5850).
Just earlier total power draw went from ~267w running MW sep. mod. fit to ~291w running MW v1.02! (with 3 CPU cores running Asteroids@Home).

Unsurprisingly GPU temp's & fan speeds go up a bit with these WUs too.

Was just wondering what makes these WUs so much more demanding?

Oh also does anyone know roughly what proportion of WUs are the MW v1.02 type?

Can nobody help me with either question?
If not then I'll have to count the 1.02 WUs on each page :(, I only need a rough idea (to work out power usage).

I just don't think many of the rest of us do the monitoring of our power usage like you do, we just pay the bill and move forward.

ps IF you are running your pc's on standard household circuits feel the outlet covers, if they are warm take one or two pc's OFF that circuit before you burn your place down!! I found some I could fry an egg on before I called an electrician in to run me all new dedicated circuits.

I lodge & so I don't pay the elec bill directly, I pay her a monthly fee for running 1 PC 24/7, hence I need to know a rough idea of power usage.

I don't know what you mean by outlet covers, do you mean the mains sockets?
If I were running multiple PCs on a single socket I would at least do a rough tally of estimated power draw from them, I would think that be obvious ;).
You were lucky not to torch your wiring! :Q, pity you don't have a power meter ;).

Oh & btw I've found many DCers do monitor power usage like that, over the few forums I'm at or been too in the past. Certainly quite a few of my TA team mates do.
It's worth monitoring power from time to time to make sure your not wasting power on old or slow gear over time, or when 1st overclocking something to not go too high on the voltage & chewing up a lot more power for just a few % gain etc.

Looks like I'm going to have to do a tally of the MW WUs, fun! :P lol.

I also monitor my power usage and I've noticed MW 1.02 draws quite a lot of power. I really don't know why either, other than it seems to max out the utilization of the card.

Is that on your 7870 XT? What does the power jump from & to?
Other WUs don't max out your GPU?

So I've just counted though 25 pages of WUs. Which is not even 24hrs worth!, but at 500 WUs in total I think that's enough, anyway MW v1.02 WUs compromised 31% of them, incase anyone else does care ;).
Oh fgs I've just realised that doesn't really help anyway!, 1.02 WUs are either the same time, 1/2 the time or 1/3 the time of mod fit WUs.

Lol, I've just remembered my power meter measures kWh & I've just realised it clocks the time it's run!
So I've got 166hrs & 43.56 kWh (total power draw is ~267w or ~291w running MW on the GPU @850 MHz, RAM 500 MHz & A@H on 3 cores), which means an average power draw of 262w ...... that's not right, even accounting for the odd hr or 2 I watch videos on some nights (& thus pausing MW, power drops to ~211w). Hmm can't think why it would be too low, oh well I'll just have to reset it.

No I do not have a power meter for each pc, I have one that hangs outside the home that tells the electric company how much to charge me but that is it, my home is all electric though so looking at that would be useless for figuring out how much my pc's use.

Outlet covers are these:


Even though most of mine are plastic they still got very warm, the metal ones EXTREMELY warm! All are nice and cool now though as 99% of my pc's are on 3 dedicated circuits.

Cool :),literally lol.
Yea their called mains sockets or just sockets, at least here in the UK, btw where are you? - nm, I see it's USA.

I don't keep my power meter permanently plugged in, but I use it after h/w changes. The meter's not essential but it is interesting & useful :), oh & it only cost me £25 from Maplins (8 yrs ago).

Btw, how many PCs do you run/crunch with?

Oh & so far, 4.89 kwh @ 19hrs 39 min., an average draw of 249w, I did watch 2-3 episodes of Supernatural last night so the GPU was suspended then. I'll let it run longer before settling on an average.

Yes I am in the US about 30 miles South of Washington DC.

I have 15 pc's running but only 13 crunching right now, my wife owns a Mac and our agreement was if she doesn't run Boinc I do not provide tech support, and since she doesn't like me telling her what to do she doesn't run it on her Mac. Her tele-work laptop is also running almost 24/7 and I can't put it on there. Most of my pc's are Win7, I do have one with Windows Home Server on it and one with XP on it though.

Lol, well I guess you guys came to an arrangement of sorts ;).

Nice crunching fleet you've got! :), just got 2 here (well bar the legacy Celeron 366 @550, but I haven't used that in years!), & as I mentioned only my main rig is on 24/7. Electricity is expensive here.
I do occasionally crunch on my 2nd rig for a brief boost.

Electricity is sort of expensive here too, for the US anyway, no where near what you pay though! BUT working and retiring here does have it advantages, one local government is now paying STARTING workers 40K per year!! That is for welfare workers that DO also have a college degree, ANY degree will do though. As you can imagine they have over 50 people applying for each job, but ironically less then 25% make it even one full year before they quit and do something else. At least 33% of the rest apply for a transfer to another job within the local government after their first year is over. Too many regulations and 'clients' unhappy, thinking they can bully the employees into breaking the Law. Welfare is administered by the local government which kicks in some money, the State which has more regulations and kicks in more money, and the Federal government which also has some regulations and kicks in the last of the money. The "manual" is actually about 6 3inch thick 3 ring binders that you must flip back and forth thru to find what you are looking for. It is also on line but not easily accessible, it is pretty much a copy of the pages in the binders that were scanned and put on line.

That's a decent starting wage!

Right, for anyone interested, I've got a total power figure usage (again) now, 42.33 kWh over 164 hrs, which gives an average draw of 258w ...... ok well I guess the 1st average was about right afterall! lol.
I guess the MW 1.02 WUs don't consist of much of the MW data &/or that watching videos has a bigger effect on dropping power usage than I thought! :). I did run LHC@H instead of A@H for a couple of days which lowers power draw by about 10w.

So adding the earlier figure of 166 hrs & 43.56 kWh + the above gives 85.89 kWh over 330 hrs (13.75 days) for an average power draw of ~260w. I'll settle for that!

Did you manage to see the power difference?

Greetings,
I too have issues with these MW 1.02 WUs - they slow down my computers so much as to render them unusable, and the only option I've found so far is to suspend, abort and remove them. It has gotten so bad, I've decided to disconnect from Milky Way altogether. I can't believe that these people are not capable of designing their work units to avoid such side effects.

I'm signed in to several different projects across 3 different computers, and these 1.02 MUs are the only ones which seem to cause this problem. Until this unpleasant situation is resolved, I'm afraid Milky Way has lost my support.

Also your problem has nothing to do with my question (mine isn't a problem, just a question) so please post a new thread where it's a different issue.

Regarding 1.02 WUs, you could of just deselected 'Milkyway@home' in the online preferences under Run only the selected applications, that doesn't stop all MW WUs btw, just the Milkyway 1.02 ones.
