When i send a request for more work the server says:"There was work but you don't have enough disk space allocated"

What does it mean?How can i solve this problem

Thank you all

Climate Prediction needs at least 700MB of disk space to run (if you are trying to run more than one on a hyperthreaded processor then you will need double that). You will need more space when you start your next WU as it leaves about 300MB on disk.

To change your settings go to 'Your account' select 'General Preferences' and 'edit my preferences'. Then set the figures so that BOINC can use at least 700 MB, but preferably 1GB or more.

If you do not have room on your current drive but do on another one, you can install BOINC on that drive.

If you have room now but are worried about running out later, you can store data from finished projects on CD/DVD.

I have more than 700 MB free on my disk and boinc can use more than 1GB so i don't know what to do

The setting (general preferences)

"Use no more than xx% of total space"

might be a problem too. If you have 1GB free but allow only 50% for BOINC, it still might not fit.

If you use NTFS you can compress complete directories btw., right-click them in Explorer and in the properties you'll find "Compress". Can save quite much space on certain folders. This compression is transparent, you can still use them like "normal" folders.

Other possibilities:

Do you have separate preferences set for 'home', 'work', etc (you may need to scroll down for that)? There is sometimes a problem if they conflict, and there is a bug in BOINC which means that setting separate preferences does not work properly anyway.

When you click the disk tab in the BOINC window, does it confirm that you have plenty of space?

Ok i downloaded the work unit but i have another problem:
When i'm working also on a seti workunit the climate prediction workunit is paused,why?

If you can help me also in this case i 'll be very happy

thank you

If you have it set up to work more than one project, it runs each project for an hour and then checks to see how much work it has done on each project according to how much you want allocated to each project. It then pauses one of the projects and works on another one for the next hour. Then it does that again.

I am getting the same problem.
I have 25 Go free space on my Hard Drive, here is my config for "Home".
What am I doing wrong?


Separate preferences for home
Do work while computer is running on batteries?
(matters only for portable computers) no
Do work while computer is in use? yes
Do work only between the hours of (no restriction)
Leave applications in memory while preempted?
(suspended applications will consume swap space if 'yes') no
Switch between applications every
(recommended: 60 minutes) 30 minutes
Confirm before connecting to Internet?
(matters only if you use a modem) no
Disconnect when done?
(matters only if you use a modem) yes
Connect to network about every 1 days
On multiprocessors, use at most 2 processors
Write to disk at most every 60 seconds
Limits on disk space and memory used by BOINC:
Use no more than 1 GB
Leave at least 0.1 GB
Use no more than 5% of total space
Use no more than 75% of total virtual memory
Limits on network bandwidth used by BOINC:
Maximum download rate: no limit
Maximum upload rate: no limit

I suggest you try increasing
Use no more than 5% of total space to a larger percentage and the use no more than 1GB to at least 2 or 3. 1 WU can take up 700MB before being shrunk again so if you have 300MB from other projects, BOINC could sensibly decide not to download a CP WU.

I think it makes more sense to restrict BOINC in the following way:

Leave at least 5 or 10 GB free and
Use no more than high% of total space
However, this will depend on how you use your disc space and personal preferences.

As you have only one computer, I suggest concentrating on the general preferences and deleting the separate preferences for 'home'. BOINC has some problems coping with separate preferences for different locations, and you only need them if you have lots of computers and have to set them up separately for some reason (eg you only want your employer's machine to be doing the project outside working hours).

I have 3, but I will try to increase the sizes as stated by crandles

Thanks!

that did it!

I'm astounded. I'm running Boinc on a machine w/ 4G total disk space. Not going to give you a whole gig. So you're losing one contributor, unfortunately.

SETI needs nowhere near this kind of space to begin a WU . . . can you not break the tasks down more and make this a little more reasonable for contribuitors? Would that not help the overall progress of the project? Maybe not, but I'm surprised nonetheless.

Hi, Alec,

Unfortunately not. The Work Units are as compact as they can be and still get the job done. SETI and other project W/U have a different approach to their problem -- take a small amount of data and crunch it for awhile to see if it meets particular criteria. CPDN takes a parameter set and plugs it into a million-line program developed to run on Cray super-computers. It Models (currently) 45 years at 30-minute intervals for 19 levels of atmosphere for a potful of parameters. Could it be segmented? Perhaps. But not at anything like reasonableness.

(This is a topic hashed and re-hashed -- time and time again -- since I joined this project in July 2003. Can it be done? Yes. Is it reasonable to do so? No, not even close.)

To astound your view of the project even more, if you finish a Model, the Archive will consume another 330 Meg of your hard drive or CD-R or DVD-R. (It is my understanding that, at some point, boinc will reward you with mounds of cobbles for the use of your storage resources as well as your CPU cycles.)

For me, there is only one statistic that counts: # of completed Models. So far, my machines have completed more than 70. That doesn't put me in the etherial realm of users, but that's okay for me.

What matters is that science for the ultimate good of humankind is being done. I hope you will agree and stay with the project. If not now, when you get another, more powerful, machine -- as we all seem to do eventually.

A couple items from the FAQ are appended.

Cheers.



From the FAQ:

Disk space
Each CPDN model you run on your system will require around 600MB of disk space while it's running. If your system is timeslicing between projects your relative resource allocations don't just control how much processing time each of them will get. They also control the percentage of the disk space available to BOINC that each project is allowed to use. This may prevent you from running CPDN if it is given a low resource allocation (because it uses lots more disk space than other BOINC projects).



Smaller Workunits
How big are the work units?

Compared to SETI's work units, CP models are very big.
Even on a fast Pentium 4 it can take around 3 weeks.


Couldn't they be made smaller?

SETI timeslices its working units. CP work units are a model that runs for just
over 45 model years. Trying to timeslice a model would make it very inefficient
because you would have to move around a lot of large (possibly over a hundred MB)
data files. Incidentally, when you really get into this project it is nice to see
a whole model evolve rather than only part of it.


Thats enormous - does that mean I won't get credit for ages?

No you will get credit for each trickle and there are 72 trickles in a model.
So you only have to wait for 1/72 of a model.
Also you do not have to wait for someone else to validate your work.


So how long do these trickles take and what are: a model, a phase, a trickle and a timestep?

Instead of WUs, CPDN BOINC uses 'models', which are further subdivided into phases,
trickles, and timesteps.
A timestep represents a 1/2 hour of model time (not realtime).
Every 10,802 timesteps your model will trickle (report), and there are 24 trickles in a phase.
When you know that a model year is 12 months of 30 days (not 365 days),
you can work out that a phase is 15 years 1 day of model time (not realtime).
Each model is comprised of 3 phases.
Here's some rough performance numbers for a reasonably quick P4, using 1 logical cpu:


Timestep = 2.2 Seconds
Trickle = 6.6 Hours
Phase = 6.6 Days
Model = 19.8 Days


As you can see, your model will trickle (report) ~4X/day, and will complete in just
under 3 weeks (19.8 days). That is, if it were running 100% of the time.
Irrespectively, you will not see credit in your stats until your first trickle,
and your credit will increase with each respective trickle.
