1) Questions and Answers : Unix/Linux : CPDN seems to be filling ALL my BOINC disk space of 400GB (Message 52984)

Post:
Many thanks @geophi. I suspected it might be something like that.

I just deleted all 321 hadcm3s folders shown in the screenshot I just added to the album. I tried to get the properties for the set of folders, but the Properties window numbers kept going up and down and never stabilised.

The folder boinc-client > projects > climateprediction.net is now 178.5GB, so I just got rid of 265.5GB of nonsense.

I acknowledge that you tell me "there are no new tasks right now", but at least now my other projects will be able to get started again.

In fact, I just checked and a couple of GPUGRID jobs have downloaded and started. Hooray!

Months, or maybe a year or so ago, I set

boincmgr > Tools > Computing preferences... > disk & memory usage > Disk usage > Use at most


to 400.0 Gigabytes disk space

It worked nicely for a long time, but the number of tasks on standby ("Waiting to run") has gradually decreased over the last week or so, and yesterday the number of active tasks had started to decrease, so it's time to act.

I should be able to run 33 tasks - 32 on CPUs, and one on GPU (eg. GPUGRID & some SETI@home tasks).

Yesterday, that went down to 30 tasks.

Today, it has reached 25 tasks. Actually, I just checked, and now it's 23.

I've had a quick look what's happening, and I have taken the following screenshots:

1. 25 tasks running earlier today (I have
boincmgr > Tools > Computing preferences... > processor usage >
set to 100% of processors and 100% of CPU time)

2. boincmgr Notices tab (showing disk usage numbers)

3.
boinc-client
folder properties - size 447GB

4. The folder
boinc-client > projects > climateprediction.net
is 444GB

5. The folder
boinc-client > projects > climateprediction.net
has 448 sub-folders

Do you think I have some obsolete CPDN folders that I can delete?

How can I work out which ones they are?

A couple of completed tasks are showing now. Hopefully we're back on track. I'll mark this one 'answered'.

OK thanks Les.

My other BOINC projects seem to be working OK (ie. running and then uploading results successfully) since the changes that I made, so I'll just leave it to run. Hopefully CPDN will also come good.

OK thanks.

I think my best course of action is to let it continue running and see what happens.

In theory, the 32GB of RAM that I have should easily be enough.

Just out of interest: Would CPDN (or indeed BOINC) benefit in any way if I installed more?

CPDN was running successfully on my computer until 2014-10-24.

I moved BOINC's data directory from my SSD to my HDD a few days ago. I started this process first thing on 2014-10-25, and finished the process on 2014-10-28.

That appeared to have been successful, with new tasks downloading, running until complete, and then uploading.

However, it's been running in that configuration for a couple of days now, and all of the CPDN tasks that I have completed have given a "Computation error".

I had seen computation errors on CPDN previously, before I had installed all the correct libraries etc, but they usually happened at a run time of 0:00:00 (or very close to it). Now the tasks are running for a reasonable amount of time of around 40,000 seconds, and then they only give "Computation error" at the end of that time.

...Hmm that's interesting. I just looked at an example of a work unit for which I had had a "Computation error", and it looks like all of its tasks have had errors on a variety of computers with different operating systems.

Thanks for that Dave. I did have a problem previously and wanted to use the internal HDD instead of the SSD for BOINC (per my post of 20 January 2014 on BOINC site).

However the number of bad sectors was very low and I never managed to get BOINC to use my HDD, so I left it working on the SSD, and after reinstalling the operating system (due to other problems) on 25 April 2014, the number of bad sectors stopped increasing by about 3 every day, and peaked at 302 months before failing suddenly on 26 September 2014. It was at 304 when I checked it shortly before it failed.

The new SSD has been in for 5 days and it still has 0 bad sectors.

I think the thing that prevents BOINC from using the HDD is that the operating system doesn't want to mount the HDD at startup for some reason.

I had to reinstall my operating system a couple of days ago, after replacing a failed SSD. I didn't have the option of copying the 32-bit file "/usr/lib/i386-linux-gnu/libstdc++.so.6.0.16" from my other desktop computer this time.

I came to a previous post in this thread, which points to this webpage, and:

1. Tried
sudo apt-get install ia32-libs libstdc++6 libstdc++5 freeglut3


2. but found that
Package ia32-libs is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
lib32z1 lib32ncurses5 lib32bz2-1.0
so

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0


3. Then I finished installing the remaining libraries

sudo apt-get install libstdc++6 libstdc++5 freeglut3


I found that a number of climateprediction.net tasks have downloaded overnight, and are
Running
at around 10% Progress, so it seems that it is all working again.

Hooray!

Yes they were hadam3p_eu tasks, and when I checked yesterday morning they were gone, so it's all hunky-dory again. Thanks for the info.

I don't know if this is platform-specific.

I have two completed climateprediction.net tasks. They were completed a couple of days ago, and have tried uploading the results, but they keep going back to Transfers status "Upload: Retry in XXX".

I have pressed the Retry Now button about 4 or 5 times since I noticed that they had completed and were scheduled to retry the upload, without success. Each time that I press the button, or the completed tasks are automatically uploaded, the upload of each of the two tasks looks like it is progressing well (and takes about 10 minutes because most people have ADSL not broadband internet in Australia), but shortly after it reaches Progress of 100%, it goes back to Transfers status "Upload: Retry in XXX".

Here's a screenshot of the completed tasks in BOINC Manager

With Les's help, I managed to get climateprediction.net working again on BOINC. I had tried installing a million 32-bit libraries etc into my 64-bit machine, such as
sudo apt-get install ia32-libs libstdc++6 libstdc++5 freeglut3 libxmu6  lib32z1 lib32ncurses5 lib32bz2-1.0

but it still didn't work.

The final step/s that got it working again was:

1. Start a 32-bit machine that I have;
2. Copy 32-bit file /usr/lib/i386-linux-gnu/libstdc++.so.6.0.16 from that computer to (the corresponding folder of the same name in) my 64-bit computer; and
3. Make a link to the file called /usr/lib/i386-linux-gnu/libstdc++.so.6.

Hey presto!

No luck. I found Geophi's posts, which led me to juhoiipponen's post 47953, I used command
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 libstdc++6 libstdc++5 freeglut3

, some of these packages were installed, I paused BOINC, rebooted my computer, started BOINC, downloaded some fresh climateprediction.net tasks, but alas as soon as they finish downloading (and try to start calculating) they go straight to Status "Computation error".

I haven't got any climateprediction.net tasks working yet.

I was able to work on them successfully until a couple of months ago on Ubuntu 13.04, when my motherboard fried. It has been replaced, I have freshly installed Ubuntu 14.04 and I am able to use 7 other BOINC projects, but not climateprediction.net so far.

I've read through this post. It sounds like each contributor has had a bit of a go, with varying levels of success (if any was commented on).

Does anyone know the actual answer to the problem?

Ubuntu 14.04 64-bit
boinc 7.2.42

Since 26.04.2014, I've downloaded 4 lots of about 10 tasks for climateprediction.net, but as soon as they've finished downloading they go straight to Status "Computation error".

I'll go and see if I can find this "Geophi" post referred to in post 48779.
14) Questions and Answers : Wish list : Smaller Work Units (Message 47832)
Posted 22 Dec 2013 by el_gallo_azul
Post:
Yes I agree. I came to this forum to request smaller work units. I've got four climateprediction.net work units running at the moment, with a typical elapsed time of 160 hours, with remaining 120 hours.

Most (possibly all) other BOINC projects that I run (currently 7 projects) are usually "ready to report" within less than 2 hours for each work unit.

I saw the comment "is unlikely to be made any smaller", and I accept that and I will continue to plug away with these 4 that I have running, but I believe it would be overall faster and more accurate for climateprediction.net to divide the jobs into smaller chunks (if possible).
