I don't seem to be able to download any work at all???

I have had a break from Climate prediction for perhaps 3 years so I am sort of new at it.

This is the message I am getting;

AM I doing something wrong?

Just joining up again after a 3 year break but there does not seem to be any work units. I see there is some available for Linux, but none for windows.
Is the project over??

I have recently upgraded from Fedora 9 to 10.
I chose to completely rebuild and that meant reinstalling BOINC.
Since I did this 2 weeks ago I can't seem to get CPDN to work. I have had at least 5 successful downloads, but immediately they start they end with "Computational error".
Is anyone else having a similar problem with CPDN downloads?
It could be that my system has a hardware problem. It is not exactly new. AMD 2400+ with 1Gb ram.
Using BOINC 6.4.5.


4) Message boards : Number crunching : Pending Credit (Message 36682)
Posted 11 Apr 2009 by John Price
Post:
As explained often before, Pending credits is one of several standard items in the BOINC software that\'s used by other projects, but not by cpdn.
This project uses <Trickles * an amount of credit>, and recalculates this once per day. The number in the Pending column is created by BOINC when the model finishes, and is not always re-written by this project\'s credit calc program.



Thanks!

I did try to search for it in the forums but without success.

Post:
Could some one explain to me how to understand what the \"Pending Credit\" tab is telling me.
It says I have 551,467.54 of pending credits!!
Does that mean CPDN is trying to work out whether these are valid credits??
As Currently my Total Credit is showing 946,270!
Does this mean I am likely some day to fly past the one million Mark when the pending credits are released?

Tried to check my results this morning and can\'t access the \"view\" computers on the climateprediction site.
It asks me to log in again and then tells me the email/password are incompatible.
Exactly the same email/password allowed me to write this message board post.


Sorry, meant to ask if others are having problems accessing their data. Also can\'t access results, still a bit sleepy.

8) Questions and Answers : Windows : Results seem to have failed (Message 23620)

Post:
I check regularly check what the graph of my results is looking like and one of them;
Perturbed Parameters for Result # 5426919
HadCM3L Coupled Model Experiment.
seems to have gone wrong. It was tracking nicely with a gradually rising temp and then shortly after the 20% point was reached it lost everything before about 1950. Is this problem with My model or is it something at the \"results\" web page.
Actually it must be at the web site as I have checked others and they have the same problem;
See Perturbed Parameters for Result # 5223265 HadCM3L Coupled Model Experiment
but this time it is prior to 1938.

Any one else have this problem?
9) Questions and Answers : Unix/Linux : BBC Climate prediction takes along time! (Message 21595)
Posted 25 Mar 2006 by John Price
Post:
I have two of these running on Linux boxes now and one of them is showing it will take 4,648 hours to complete with a deadline of 26 Feb 2007.
After 78 hours it is showing completed 1.73%.
My concern is that as I don\'t run this box 24/7 I think the likelihood of me completing this is remote. I don\'t want to run this box just to complete clim pred project as that seems to be just adding to global warming.
Is there any point in continuing this in as much as it is unlikly it will be completed in the alloted time?

Posted 15 Mar 2006 by John Price
Post:
Just a bit puzzled as when a 4.23 model crashed on Fedora4 it was replaced by what appears to be BBC Climate project.
I thought that it needed special BOINC software to run it?
It seems to be running OK if very very slow.
It also seems that the command line doesn\'t display any more and you need use the graphics in BOINC. Is this all correct? Will the project run correctly or do I need to download a special BBC Program?
The model is hadcm3lb 5.08 the Boinc platform 5.3.23
11) Questions and Answers : Windows : too many results! (Message 19506)

Post:
I am having very little success with sulphur workunits and have had a string of client errors with most not getting past phase one. and most come up with the comment \"too many results\". What does this mean?
Am I doing something wrong? Can anyone point me to information on this?
12) Questions and Answers : Windows : what happens when you turn the PC off (Message 17964)
Posted 10 Dec 2005 by John Price
Post:
Does the unit go back to the beginning of the last trickle or does it, say, go back to the start of the last day?
If it goes back to the beginning of the last trickle there would be good reason to leave PC\'s on all nght as well as the day.
I know this probably somewhere in the Q & P\'s but there is too many to go back though them all.
Is there a search function on these message boards?
13) Questions and Answers : Windows : strange RAC issue (Message 16934)

I have a similar issue. At about 13:00GMT I suddenly received a swag of results from a machine that stopped operating on 7 October.(actually I increased its RAM to 768Mg but Boinc will not allow them to merge) Host ID is 227800. it looks like I had deliver the whole of phase one in about 10 mins or so! Likewise it did not seem to alter my total credit. Also since then I have received no credit from the 7 machines I have running even though they should have been recorded and the various Boinc managers are telling me that they have \"succeeded\" in a send of trickles to CPDN.
Have I suddenly become a recipeint of misallocated results instead of being one that loses results?

More critically I dont seem to be getting any credits for the results from the machines that are still running.
Have we got a database problem? it did seem to occur on the 1st of the month. Were their any database changes at the end of October?

I can\'t see this on mine.
Where abouts is it displayed?


My machine number is 170146

It is down the bottom of the page below \"Average CPU efficiency\" and above \"Location\".

Is it to do with using Boinc 5.2.2
Windows XP Home.

p.s.

I have just realised that this machine looks a though it has been struggling with a misallocated result and I have reset the project.
Has this something to do with it?
I also notice that my Linux machine is not showing a \"Result duration correction factor.\"

I notice most of my PC\'s are set to 1.0, wheras my Atlon 64 3000+ has a figure 1.424242.
What is this telling me?
18) Questions and Answers : Windows : Problems with Sulphur Cycle (Message 16680)
Posted 20 Oct 2005 by John Price
Post:
Can you beleive it! When I took it back again to the shop it worked perfectly for two days.
I have now traced the problem to the new motherboard and the KVM switch I was using not liking each other. I switched the KVM switch for an older one and it has run for 8 hours with no problem. The old, now dead motherboard, and the KVM switch got along fine for somthing like two years.

I apprecaite the comments on various tests and I intend to use them on all my boxes to see if there are any other problems.

Once again Thanks!

Posted 18 Oct 2005 by John Price
Post:
are you prime and memtest stable?
are you overclocked?

without knowing these things and what make of board/PSU you have, this question is impossible to answer



Definately not overclocked!

Could you elaborate on \"prime\" and \"memtest\" stacble?
Is this some diagnostic software that I should run?

I have returned to the hardware supplier who has said that as BOINC is non standard software it is to blame and will not research it further. He tells me if I take BOINC off it will run perfectly! Does anyone have the figures on how many Computers are runing BOINC in windows XP Home?

The Motherboard is Asus A7V600-X.

20) Questions and Answers : Windows : Problems with Sulphur Cycle (Message 16586)
Posted 13 Oct 2005 by John Price
Post:
After a motherboard failure I have rebuilt machine (highbury)with a new motherboard and completely rebuilt the WinXP environment to Service pack 2.
First thing I did was install Boinc 4.45b as I had had some problems with the previous 4.72.
It downloads a sulphur cycle and after running sometimes for anything from 14 to 5,000 secs I end up with client error (3 times so far).
Then it tells me I have passed my daily download limit and I have to wait 24hrs.
I have set it up now to happily run einstein@home and Seti@home and they seem to be fine.
Are others having a similar problem or is it my rebuild?

Processor AMD 2400+
Ram 1 Gig.
