I see problems with several Linux clients. They report that they cannot get more work as there is not enougth disk space. Nonsence...

I can see it very clearly at one PC that has about 2GB free space. My limits are 100MB for BOINC. On that PC, SIMAP client rejects to get new work but S@H works fine. From my point of view SIMAP has a bug. Maybe it looks for free space at root disk, not for free space that is used by BOINC.

I have checked my account details at SIMAP and S@H and they are the same, the same limits.

Predictor@home reports only "no work" for several dayes. I am not sure but it can be the same problem as SIMAP, it calculates free space in wrong way.


Details:
2006-09-03 18:09:52 [---] Memory: 502.94 MB physical, 494.15 MB virtual
2006-09-03 18:09:52 [---] Disk: 4.66 GB total, 2.21 GB free
2
...
2006-09-03 18:11:03 [boincsimap] Message from server: Not enough disk space (only 92.0 MB free for BOINC). Review preferences for minimum disk free space allowed.

I have to say, that this message is not clear to me, I would like to see what is total free space too; it will help my troubleshooting. root directory has 93MB free space, but BOINC runs at /home directory that has 2GB free.

I can't answer your general question, but the reason that you're not getting work for predictor is that they are not giving out work right now. See their front page news.

Disk and memory usage


Use no more than 0.1 GB disk space
Leave at least 0.1 GB disk space free
Use no more than 50% of total disk space
Use no more than 75% of total virtual memory

As I noticed, SIMAP and S@H have the same settings; I use BAM. I am almoust sure that SIMAP has a bug in the last Linux client.

You've given yourself the answer...use no more than 0.1gb (100mb). These programs eat disk space at times...set it to 1 or more gb's (I got it on 10GB), particular if you have multicore crunching going on.

you are not right about my 100MB limit becouse:
1) I have this setting for some time and it worked in the past, SIMAP is not disk hungry (maybe I had more space in / directory).
2) I didn't change setting and I get new units from SIMAP during afternoon

Looks as problem was fixed.

Thanks for your help.

I see it now, my root disk (/) has 128MB of free space now and I got a work. It had 97MB of free space for several days and units were not sent. This is a bug in SIMAP or somewhere, it reports as free space / directory, not disk used by Boinc.

I think the way u need to interpret your settings and the actual available space on your disk is that u are in effect only giving 28mb as room too play for simap....you're bound to run into same resitrictions again i.e. change 'Leave at least 0.1 GB disk space free' to e.g. 50mb.... you're anyway dangerously low on your system drive......recommend free space is 15% for windows drives.

When i look in the BOINC disk use stats, 8 WU in queue use 21mb already.....during crunch it uses virtual disk space too from your pagefile. If also on C: the page file will grow and shrink as usage varies.

It's no simap or boinc bug that is for sure in this case.

take care.

NO, no no. You miss a point! I hope you understand directory structure under Linux and know what is mount command about. My disk, very simple:

$ df -h
Filesystem Size Used Avail Use% Mount
/dev/hda1 5.6G 5.5G 92M 99% /
/dev/hda5 4.7G 2.6G 2.2G 55% /home

BOINC is installed in /home/boinc directory, all files for boinc are there

And I beleive that SIMAP clint checks free space at /dev/hda1 disk, not /dev/hda5 as it should.

Check the system requirements table to see that SIMAP needs a minimum of 96MB free disk space. This is the disk space of the partition/hard drive that you run BOINC from, the requirements are shown for the projects only. You need to add whatever space BOINC uses up to that.

I am still not sure if you understand that SIMAP has about 2GB of free space (and cen get 100MB of it) but it is still not good for it.

You understand Windows, so I translate my observation to Windows user language:

You have two disks, disk C a D. Boinc is installed at disk D, this disk has size of 4GB and has 2GB of free space. Your disk C has size 5GB and has only 92MB of free space. SIMAP reports, it cannot get new work as you don't have enougth disk space. Is it clear now?

What about Boinc core API? Is there a call to get free disk space? It should be there from my point of view. Maybe that SIMAP ignores that API and checks free space in its own way...

SIMAP may be able to get 2GB of space, but NOT when you tell BOINC to use only 0.1GB of space for all projects.

That setting of Use no more than 0.1 GB disk space is a setting that all your BOINC projects will use. Even if the only project you run from under BOINC is SIMAP. BOINC uses around 10MB to install itself in. So you have 90MB left for SIMAP. Since SIMAP wants a minimum of 96MB, you have not enough space, no matter what operating system you use.

This is a problem I run into all the time. Some projects require a mininum overhead of free space available to BOINC. I am currently running into this sitution with malaria control. This projects wants to have 200MB free. Also had this when Predicator was running, it also required 200MB free for boinc to use.

That free space seems to be calculated from:
"setting of Use no more than xxxGB" - "minus the space currently used by BOINC"

So if you have "setting of Use no more than " set to .25GB and all BOINC system files and projects are using 51MB, Malaria control will not run.
That is the .25GB(250MB) - 51MB = 199MB available for boinc.

Since the above 199MB is below 200MB Malaria control and other projects will not run. What I have found is for some projects to run you have to take the amount of space you want to alloc to the projects and then add 200MB to it for BOINC use. So if you want to use 100MB(.1GB) for a project, you have to set "setting of Use no more than" to .3GB.

I thought that preferences (like disk space) are project specific. I can set them at my project account pages. Different projects could have very different requirments for resources (one project is memory hungry, other needs a lot of disk space).

But from your replies I understand that there is something like TOTAL disk space that can be shared by all Boinc clints. Why in that case I can set different preferencies for different projects? It will be better to have a Boinc client account that will keep this information for all projects (I don't know about such account; BAM can be used for this but it is something different).

SIMAP uses about 35MB of disk space on my PC, at least this is number reported by BOINC Manager. It is not nice from SIMAP to ask for almoust 100MB anyway...

Thanks for link to WIKI, it is very usefull artickle!

There are three groups of preferences -

* Forum. This is for that particular project's forums.
* Project. These are options which are specifically for that one project.
* General. These preferences are shared between all projects. Modifying them on one project's website will affect all projects. Not every project uses every general preference - some are ignored, and some are relevant to specific versions of the boinc manager.
