Hey People out there,

as we are all fighting with longer and longer WUs, let's find who has crunched succesfull the longest WU.

Rules:


  • CPU-time Counts
  • only real validated results



My longest WU until now is 236,802.60 seconds and gave me 762.15 credits

Come on, show me that you can beat me

I had a pair of those running last night but just my luck the power went out at 11pm until midnight and when I booted back up they turned into errors.

Now if I could just get the power company to *suspend* my tasks before that happens...........even lost one Einstein GPU task.

But most of the tasks survived this......only the laptop lost the Atlas tasks so I started another pair after reboot.

With the previous 1.28 they would never finish but so far no problem with the 1.29........as long as the power stays on or I *suspend* when rebooting for other reasons.

There is something not right with those results. My i7-4771 is only about 2 times faster than those CPUs in terms of integer speeds, but my longest CPU time is only 66,329 seconds (850 credits), which is less than 1/3 of those times.
http://atlasathome.cern.ch/results.php?hostid=8943&offset=0&show_names=0&state=0&appid=

I am running 4 or 5 Atlas work units at once, with one or two cores on CPN or Cosmology, and the other two supporting HD 7790 GPUs on Einstein. Are you running short on memory and swapping data to disk? That would slow things down. I have rebooted several times without taking any precautions either with no problems. Do you have "leave applications in memory" enabled?

Jim,

as told from the ProjectAdmin the actual WU-Set has total different runtimes; from very short to very heavy runtimes.

You can see a lot of WUs with "normal" crunchtimes in my history, so the machines are doing well and mine have all much more Memory than they would need.
I run 3 Tasks on 8 GB, 4 Tasks on 16 GB and 6 Tasks on 16 GB

Yeti,

OK, thanks. I probably won't get enough to compete in this tournament for a while longer.

I hope I don't spoil the fun, but I ran a quick DB query and MAGIC is the clear winner of this game :) Yeti I'm afraid you are only in 7th place at the moment with 430544

I will have to live with it;-)

What is the max time in seconds by Magic?

And congratulations to Magic:-D

Thank you

That one task was just over 96 hours completed

But right now I have 3 more that will pass that one.

One is over 117 hours and is almost 99% and then a pair or tasks just over 95% with 89 hours so far.

Then a few others that look like they may be around 50 hours each when finished.

Wao, it seems you have an Abonnement for these Monsters.

The new Watermark from these results is now: 348,624.80 Seconds !

Really great !

How is your electricity bill? From the start of my third PC, this one with a graphic board, my kWh/month rose from 177 to 263, with my bimonthly electricity bill going from 90 euro to 123 euro.

I may have another one that is running that will pass all of my previous record tasks Yeti

It is at about 99.450 right now after 142 hours......running slowly but I still see it continue running.

I will check it again later tonight (5:21pm here now) so maybe midnight.

Yes Tullio you will see you light bill go up when you run those GPU tasks over at Einstein.

Those video cards running 24/7 do that work much faster than the CPU method but use more power which is why we have to have better PSU's and watch the GPU card temps.

I have been running 6 or 7 GPU crunchers at Einstein for almost 3 years so that has cost me quite a bit as far as the power bill.

It is about $60 per month extra for me.

It tends to make you try to conserve in other ways around the house.....and I try to just forget about how much I have to pay......until I get the bill.

I used to get power bills every 2 months but they switched power to another company here after 95 years and they bill me monthly.

And it is winter so we have to heat the house until May.

I know we have a few other members running even more GPU crunchers than I have at home......and some lucky ones who have it running on computers NOT at their homes so they get that for free.

I always check for the latest cards and processors and was tempted to build a new machine since my #7 host finally gave up (got tired of installing drivers and OS and bios)

So if you don't have the extra money just stick with what you have.

Message 1461 - Posted: 26 Nov 2014, 20:55:59 UTC - in response to Message 1440.

These comments about the electricity costs are very interesting. We have been discussing in ATLAS the real cost of ATLAS@Home compared to the computing resources that normally crunch ATLAS data. A rough calculation was that 1 home PC running 100% CPU adds around 20 euros/month to the electricity bill (of course electricity costs vary per country, season and time of day). But for example, would it be more or less expensive for a university to use idle time on employees' desktops or buy a dedicated cluster (which would be more energy-efficient)? Anyone have any numbers on this?

Running the Atlas tasks use quite a bit less electricity than the tasks using the GPU (such as Einstein tasks)

CPU tasks here using the employees' desktops might be the best way but that also depends on what they have as far as processors and RAM

Probably cheaper than buying a dedicated cluster plus the power to run them.

And of course your desktops would be running only Atlas tasks and many members here are running other tasks at the same time (I also run the Einstein GPU tasks and vLHC along with the Atlas tasks)

But I have never had a problem running those vLHC-VB tasks X2 along with these Atlas-VB tasks (other than the Atlas tasks being very long)
