No overclocking. This computer is running stock from Dell purchased around a year ago or so.

Hi

Can anyone suggest a way to by-pass User Account Control, please?

If I get a download which requires a re-start and I am not there, I lose hours of crunching time.

Can Microsoft not be persuaded that BOINC is a safe program?

Regards

Mike


I am running a Vista Test machine in our labs here at work. I have been running Boinc fine with User Account Control on. I\'m trying to see if all of our programs work fine leaving it on.

What downloads are you referring to that require a restart? If you are talking about Windows updates just set them to prompt you before installing.

With the amount of memory the computer has, 512Mb, it\'s best just to let it run one of these HADCM models at a time. So as Les says, the max CPU activity you\'ll see from the model in task manager is 50%.

But while the model seems to be running for Jeff, why isn\'t it trickling? The funny thing is that the model that completed successfully trickled until 3 Oct ie after this model had stopped trickling.

A In the Activity menu of boinc manager, is network activity allowed?

B When you open boinc manager does it say Connected to localhost at the bottom right of the screen?

C Have you made any changes to your firewall setup since mid-September?

D When you still had two models, before the other one completed in early October, did you let them both run at the same time or did you suspend one while the other ran?

E Jeff, could you please type out for us the exact figures you see in your boinc manager tasks window for CPU time, % completed and Time to completion. Then the same information again a few hours later.

(I\'m sorry, I realise this is a bit of a pain. But with a model that\'s so well advanced I think it\'s worth digging to explore the problem.)


A. Network activity is always available
B. It is connected to localhost
C. No changes to firewall
D. Both models were running together for quite a long time then I suspended one of the models since I was unsure if I would have enough time to complete both models and this is a single core single cpu system.
E. CPU Time: 2963:18:32, Progress: 75.226%, To completion: 963:16:52

Jeff, don\'t abort this model yet until we\'ve worked out what\'s gone wrong. There may be nothing wrong with the model and the problem could be something simple to put right. Astro is quite right in wanting more information.

At first I thought your model was looping (getting stuck at some point and continually going back to the previous December to try the same model year again). But if that was the case, you\'d see the CPU time increasing while the model wouldn\'t progress to its next trickle point.

It last trickled on 21 Sep at timestep 3110400 and at 3048 hours CPU time. I\'ve converted the seconds shown at that trickle to CPU hours. So you\'re right in saying that the CPU time has gone back. Presumably in boinc manager it still says 2963 hours.

Could you please try to answer all the questions.

1 Are you getting any boinc manager messages about the model?

2 Is this computer running tasks from any other project?

3 In your task manager performance tab, what CPU usage do you see?

4 Have you restored this model from a backup? (What you are seeing could I think be consistent with you restoring a backup made in mid-September when the model was at about 2036, and the model failing to restart after the restore.)

5 In your boinc manager Activity menu, have you selected Run Always or Run according to Preferences?

6 In your boinc manager Tasks window, what does the Status column say for this model?



Here are the answers:

1.) No messages about the model.
2.) This computer was dedicated to running only CPDN. This is a single CPU machine and it was running two CPDN models at one time. It completed the other one successfully.
3.) CPU usage is erratic but never 100% like it should be. It seems to be going between 30% - 50%.
4.) No backup on this one.
5.) I have it run according to preferences. My preferences for all machines is to run after two minutes of no enduser activity.
6.) Normally it says it is running.
7) Questions and Answers : Windows : Sticky - My model won\'t finish in time (Message 31130)

Post:
The 1 year deadline for completing a model is arbitrary - the BOINC server software requires that a completion date be inserted, as this is used by the other, shorter projects. (See list here.)

Provided that a computer returns at least one trickle a month, then the data will continue to be accepted well past the one year \"deadline\".
Delaying trickles for longer than about 6 weeks will cause the server software to regard the model as \'lost\', and it will mark that data set for possible re-issue to another computer.

The only exception to this \'no deadline\', is if the project finishes, and models haven\'t been returned.
Examples of this are the THC (Thermohaline Circulation Experiment), and the SAP (Seasonal Atttribution Project).



So if I have computer that hasn\'t reported in more than 6 weeks should I still fire it back up or should I just abort the unit?

Unfortunately, lack of information keeps us stabbing in the dark. (My intuition is weak.)

Clearly something keeps CPDN from getting time on the machine. It\'s possibly some change you made to Preferences. Did you limit the hours it can run? The conditions under which it runs?

If set to run as a Service, is it actually running?

Did you add another Project or reactivate another Project? If so, boinc could be throttling CPDN while collecting Long Term Debt.

Did you add some long-running non-boinc work at an above-low priority? If so, boinc, which uses only otherwise unused CPU cycles on your machine, wouldn\'t get a chance to run.


Something must be wrong. It must be running in some sort of loop. I just checked it again and it says it has only 2963 hours of CPU time. It should never show less time. I think this workunit is screwed and I will have to abort it.

Post:
What happens in the Time Step count, in Tasks tab/Graphics? Does it progress smoothly but slowly?
Does it fall back a bit, then reprocess the same several TS over and over again?
Is it hung?
Is the globe blue?
Any clues in Messages?
What does it say in Tasks/Status? (The stopped clock suggests the Run is stopped.)


The graphics are disabled on this installation. Since I last posted it shows the CPU time at 2964 hours when it should have way more than that. It is set to always run. It is currently at 75.232%.

Should I just abort it? It also says it is at 2963 hours and I have let it run for days and it should have gone past the 3000 mark but does not seem to be making any progress.

I just saw a cool message in my boinc:

I think I am getting some credit soon...

I always prefer to buy Kingston because they test each and every single memory stick. They will test each memory stick for a full 24 hours to let it burn in a little. If it does not pass this 24 hour test they will not sell it. I am not aware of any other companies that do that.

That\'s a heavy overclock! Water-cooled, I presume, and good memory.

Be advised that this Model doesn\'t always \"play nice\" on O/C machines. However, if it\'s okay after hours of Memtest-86 and a day of Prime95, you should be okay. Regular backups are recommended -- just in case... (I did them every three days during Spinup, five to six days now. Essentially, its determined by how much you\'re comfortable with re-running after a crash.)


Actually, my machine is only air-cooled and 100% stable! This is the best overclockable chip I have ever found for the price. Right now, I am running at 3.5Ghz with an 824Mhz front side bus. I am also using Kingston memory, which is a very good brand. My current setup only became unstable when I got it up to 3.7Ghz. I can only imagine how high I could overclock it if I had watercooling or started messing with the core voltage.

I firmly believe in backups, especially since I am a Network Administrator. I will need to do that along with the rest of my system.

Just a sidenote, my CPU is overclocked more than 50% so it probably won\'t take as long as you mention.

Also, the graphics button on my Boinc is greyed out. I think I did the service install. How can I fix that?

I have been running CP for 12 hours total now (over the last few weeks) and I still have no credit. Is this normal?

Also, everybody refers to their models being on certain days. How do I tell that on mine?
