Are you shure that 5KT44 is a solid `dry` capitulator ?
not just an ordinary `wet` electrolytic in a metal can .
Well this is milkyway@home , you just made the next universe big bang . . . .
Good photo .

Yes , new work is arriving . zero`s and the odd `one`
ok , so maybe I am an `odd one` :-)
4) Message boards : Number crunching : Run Multiple WU's on Your GPU (Message 73871)
Posted 19 Jun 2022 by .clair.
Is it safe to run more than 1 task if GPU usage is sitting between 70 and 76%? Each task is running for 102 seconds on average

Yes , you will see a good increase in throughput ,
BUT , keep an eye on GPU temperature , don't let them go above 70c long term 60c is better ,
and less is even better .

Well , I have just done some _3 and _4 , but there are only 477 left `unsent`
I hope the N-Body Simulation work generator has set its alarm clock for work in the morning :-)
At the moment it is not even showing to have one on the server status page !!

was there something like more than 5 jobs in a workunit causes the command line parameters to overflow / run out of space
or was that something else ?
9) Message boards : News : Nbody WU Flush (Message 73271)
Posted 3 May 2022 by .clair.
Well, based on the number of Nbody WUs that are waiting to be sent, it looks like the WUs that need re-validation were kicked back to the surface! I'm going to let things run.
If you wind up with problems getting work, please let me know and I will figure something out.
If we can just let this run then I think all those "stuck" WUs will finally be processed, although it will take a while for people to work through 11M of them...

Seems like a good time to leave the nbody_work_generator offline for a while till the 11M backlog gets crunched
10) Message boards : Number crunching : 1 of my 6 nodes, keeps timing out. (Message 73078)
Posted 23 Apr 2022 by .clair.
Looking at the time the server gave you to compleat the tasks , you do return them quickly ,
the difference between `sent` and `deadline` was only 90 minits , crazy short deadline , no chance to crunch them
most tasks have a deadline of several days .

The deadlines are remarkably generous.....

The N-Body Simulation I have atm have a 12 day deadline .

deleat all text then put only two blank spaces , post it , and the post self destructs , vanishd
Though you may have to clean the sticky bits off the screen afterwards :-)

Unfortunately the amount of people processing N-Body seems to be declining which is the opposite of what we need.

On the server status page in the "Tasks by application" section , for the n-body tasks it states "Users in last 24 hours" of only 138 ,
Am I reading it wrong ?
is their realy only 138 crunchers doing n-body ? {however many computers they have got}
If so , no wunder it is taking so long to reduce the que , even with the reduction that haz been done today .

Is the mortality rate for GPUs any higher than CPUs when running tasks such as this? With their sky high price these days it's a costly piece of hardware to lose.

I've never lost a gpu in 20 years of using them. Only thing that can break is the cooling solution. And replacement fans or conversion to water blocks is the solution.
What's the oldest GPU you've ever still had running?

I have HD4650 {AGP slot and XP32} running MooWraper that runs cool and overclocked {tick , tick , tick , boom . . . . }
But here on MW I had two 7970`s cook , I always kept temps below 70c , though they where the single fan `hair drier` kind , now I prefer to keep temps below 60c for longer life
The bottom of a set of three on the mobo slots was {still workz ok} a twin fan , now I wont but any single fan `coffin` coolers on high power cards.
And replacement fans from ebay china have always worked for me {most fit ok}

... sorry, forgot to take my sunglasses off !
Sorry, I'm from Scotland. What is "sun"?

I think that will be `sun microsystems` they do computer stuff ;-)
Today here in Cumbria its been snowing little snowballs and the mountain tops are with with it .

So, new issue. I just buildt a new system and added Bonic, and am getting the message from this project that "N-Body Simulation needs 50.00MB more disk space. You currently have 0.00 available and it needs 50.00MB." I have 20gig available for use by Bonic and cannot figure out where the additional 50mb needs to be configured. Can anyone assist?Ron

We had this problem over at rosetta@home where the disk space used by the python projects is very big
From the `options` tab of boinc manager , then `computing preferences` then `disk and memory` tab , try setting it at
Use no more than - 100 GB - {Just set this to something BIG}
Leave at least - 0.01 GB free
Use no more than - 99.9 % of total

Boinc will only use what it needs
This is from my thread on the problem over at Rosetta@home

I still have many Separation tasks from 30 Jan 2021 on my tasks page , either `Completed and validated` or `Completed, validation inconclusive`
I have hundreds of them , if others have the same this may clog up the database a bit ,
I don't know what it would take to clear them out , though it may help .

Thanks for letting us know. I've just found another of those rare old DP cards, four running MW now. The smoother things run, the more we can get done.
Five. A good way to get MW cards is to search Ebay for faulty ones. Fans are easy to replace, power connectors can be resoldered, and the one I've just ordered (providing the seller can make Furmark run ok) is less than half price {b]because there's 2 irritating blue vertical bands down the screen on all outputs[/b]. This doesn't matter for crunching. Was it odd for me to feel sorry for the sick card?

That's odd , I recently looked at a card on ebay that had that fault in the description and wondered if it would affect gpu work on Milkyway ,
I chickened out and bought an other XFX7970 , one described as having noisy fans , Yes, ebay china has fans for most cards :-)
