The latest BOINC client for Android lists only one project, "BOINC CENTRAL". Is this a bug or a feature?

Maybe I just choose a wrong Android device for my test. That was an Android tablet with INTEL CPU and it is possible that BOINC client filters projects with architecture information. When I tried to install the same Android client to smart phone with ARM CPU, I see full list of projects, just as expected...

The latest BOINC client for Android lists only one project, "BOINC CENTRAL". Is this a bug or a feature? I cannot find any information on this change in release notes, why other public projects were removed from the list. Other projects could be added with URL but that option is well hidden and entering any URL on Android device is a pain...

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!

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...

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.

What are your General prefecence setting for
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 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

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.

Best to ask this on the BAM! forums.


Well, it is design feature. BOINC client uses username/password to connect to BAM. That is not smart design; from my point of view after first connection based on username (or email) and password, some key should be exchanged and that used latter for accesss. So, when usrname or password will be changed on BAM side, clients will not be affected.

Workarround is to detach boinc client from BAM and attach with new username again.

BOINC 5.4.9 running at Ubuntu Linux 6.06 x86.

I have BAM account at boincstats. I noticed I can change username there. I did it. I failed to synchronise BOINC client with BAM account after that change.

I understand that it is risky idea to change username but as it is enabled why not try it. User accound has some ID, that is not changed, email address is the same as well. Username should not not be the primary key.

Is it a BOINC client bug? Or design limit? It seems that I cannot even get new work units after username change in BAM. I noticed this on SIMAP project. My SIMAP account was changed correctly, new username is there.


When I do "SYNCHRONIZE with BAM" in my boinc client I receive error "Failed to update account, user not found!"

Maybe it was fixed. But this bug hang the boinc client. I had to kill (kill -9) boinc client and to start it again. All projects were affected by this crash, nothing was computed, CPU was idle for several days. My boinc client runs on Ubuntu 6.06.1...

Is it possible to design boinc client in the way to be resistant against bugs in the projects modules? Single bug in one project can stop all projects now... :-(

16) Message boards : BOINC Manager : Boinc manager canot recconect with password
Message 4882
Posted 1 Jul 2006 by psl
This is problem from the past, it is still valid with 5.4.9. I use Boinc mnager to connects to clients protected with password. Once connected I can see client data. In the case I restart client, Boinc managers shows message "Would you like to try to connect again? YES/NO". When I select YES, manager never connects but shoes message "The password you have provided is incorrect, please, try again. OK".

As there was no dialog for password, it is clear that Manager have to remember password used for connection. It ignores password now and it is bug from my point of view.
