1) Message boards : News : Disk failure on the main project server (Message 7638)
Posted 3 May 2017 by Profile Teemu Mannermaa
Main project server failed about 36h ago due to I/O errors because of bad sectors on it's hard disk. I've migrated the data to the secondary disk and the project services are now recovering. There might be few tasks affected (will be shown as download errors) as some generated data files were not recoverable.
2) Message boards : Wish list : Raspberry Pi Support (Message 7562)
Posted 5 Jan 2017 by Profile Teemu Mannermaa
Any possibility for support for Raspberry Pi in the future?

Only if there will be a Dnet Client available for it as I don't think it can run apps as is from other Linux distributions.

3) Message boards : News : Status update (Message 7561)
Posted 5 Jan 2017 by Profile Teemu Mannermaa
Year 2017 is upon us and it has been insanely long time since my last activity on these message boards. So I wanted to let everyone know that I am still around, just hiding in the shadows due to various reasons. My main priority regarding Moo! Wrapper project has been to keep it up and running at the current level. I am very aware that there are various issues and improvements pending that should be addressed and I'm sorry about lack of progress on them. Hopefully I will manage to get these done eventually.
4) Questions and Answers : Getting started : GPU requirements for Moo (Message 7560)
Posted 5 Jan 2017 by Profile Teemu Mannermaa
I looked on the website and couldn't find specific information stating GPU requirements. I ask because my GPU (GTS 250) is old and I don't know if it is still supported in this GPU project.

All the requirements that are known are listed in the post. However, best way to test is to try running few work units and see what happens. Quickly looking that GPU should work, as long BOINC Client detects it. Might be a bit slow to crunch but I'm sure you know that about old GPUs. :)

5) Message boards : Number crunching : login info through MooWrap? (Message 7559)
Posted 5 Jan 2017 by Profile Teemu Mannermaa
When I look at the status pages, I see "" as the email/username listed for me.

Yeah, that's the default we use to prevent the BOINC Email address getting revealed. You can set the email used in Dnet Client in project preferences if you wish to use some other email.

1. Does it really matter that I can't get to the password protected portion of the stats page on

Depends, you need access if you want to change the settings in Dnet Statistics for that account. One such thing is the team to which the account contributes to (in the Dnet Statistics).

2. Is there any way to get/reset the password while retaining the "" format?

If you want that password, you can request it on their site and then notify me via private message here and I can forward the password email to you. This is manual process until we can implement some kind of special automation for this between dnet and moowrap.

6) Message boards : Number crunching : Wrong email address in stderr (Message 7558)
Posted 5 Jan 2017 by Profile Teemu Mannermaa
I had another look today and it is still the old email address which I do not have access to in the stderr. So you are passing an invalid email address over to

The email address used in the Dnet Client is set in project preferences. It originally defaults to a special moowrap address. Any custom email set in the preferences won't be changed if you change the BOINC email.

Please, go to the to change the project preferences and the email should be fixed.

I assume that this was not thought of or is it that you do not want to create a new account and then join them together ??

Both addresses will exist in Dnet Statistics server and joining will need to be done there. There's a retire function available when you login with the old email address and go to edit your information.

7) Questions and Answers : Windows : Switching CUDA and OpenCL (Message 6945)
Posted 16 Jan 2016 by Profile Teemu Mannermaa
BOINC downloaded CUDA3.1 and I want to switch to OpenCL but can't find suitable option.

There's currently no way to force CUDA vs. OpenCL but BOINC is supposed to send you both units and start preferring the one that's faster. Have you gotten any OpenCL units yet or are you still only getting CUDA ones?

8) Message boards : News : Outage due to primary disk failure (Message 6873)
Posted 5 Dec 2015 by Profile Teemu Mannermaa
Due to the primary disk finally failing completely there was about 8h of downtime for the project today. For some reason the disk failure brouht the server down even though we are running from the backup disk since July.

The failed disk has been replaced now and the project is slowly catching up with work distribution. Apologies for the outage!
9) Message boards : Number crunching : Doing 2 WU's instead of 1 (Message 6870)
Posted 4 Dec 2015 by Profile Teemu Mannermaa
For Seti we were able to modify the programming so it does multiple WU's instead of 1 by switching settings from 1 to .5. Is that possible here?

Not really, unless one uses the appinfo/appconfig features of BOINC to change estimates. However, a Dnet Client WU should be almost fully using a CPU and GPU so adding additional WUs wouldn't make things any speedier.

10) Questions and Answers : Unix/Linux : 195 (0xc3) EXIT_CHILD_FAILED (Message 6854)
Posted 25 Nov 2015 by Profile Teemu Mannermaa
However, all I get is the task runs for 16/17 seconds then fails:


It's not a new problem. See:

That particular problem has been solved by using OpenCL apps for newer cards. Not sure why BOINC Client/Server are not preferring OpenCL apps for your host.

However, that error code might be due to for some other reason. Looking at your recent error results, it seems the error is "Unable to initialize problem manager. Quitting..." which is a bit different problem. The Dnet Client is also not able to detect any ATI cards on the system.

In any case, switching to OpenCL app would be the solution but we'd have to find a way to make BOINC Client/Server prefer that, and only that. Currently I'm not sure how to do that.. :(

11) Questions and Answers : Windows : Is there a 64 bit WU for my GPU? (Message 6853)
Posted 25 Nov 2015 by Profile Teemu Mannermaa
The server only offers Client 1.04 windows_intelx86 (ati14)
I'll setup an app_info.xml to force the 64 bit app if there is one.

There's no real benefit on having the wrapper/client logic parts as 64-bit for GPU clients. This is because the actual work happens inside a GPU, which is not related to bits in the executable. That's why only 32-bit apps are available for GPU crunchers.

Even if I'd want to provide a 64-bit wrapper for GPUs, upstream only provides 32-bit GPU clients anyway. Therefore, I'd recommend not to worry about this.

Is there some particular reason you'd want a 64-bit wrapper/client?

12) Questions and Answers : Web site : Cannot upload avatar, nor create profile (Message 6852)
Posted 25 Nov 2015 by Profile Teemu Mannermaa
Getting this error message when uploading an avatar:
Fatal error: Call to undefined function gd_info() in /home/boincadm/projects/moo/html/inc/ on line 23

And this when creating a profile:
Fatal error: Call to undefined function imageCreateFromJPEG() in /home/boincadm/projects/moo/html/user/create_profile.php on line 128

Interesting.. wonder if there's something wrong with jpeg-avatars. Can anybody else confirm they have managed to create avatar/profile lately and if so, was the picture jpeg-format or something else?

Also, retrying with a png-image is something I would be interested to hear results from.

13) Message boards : News : Short outage (Message 6719)
Posted 18 Sep 2015 by Profile Teemu Mannermaa
We had a few hours of outage today due to network connectivity issues at our server hosting provider that affected our DB server. Things should be stabilizing again barring any pending network maintenance.
14) Message boards : News : Fresh work available! Come get yours! (Message 6662)
Posted 22 Jul 2015 by Profile Teemu Mannermaa
Keymaster is back online, at least temporarily pending more hardware replacements, so we are now generating fresh work for your hungry computers. Come get some and get your crunch on!

Thanks for your patience and understanding during this extended work outage due to upstream keymaster hardware failure.
15) Message boards : News : Out of work (Message 6660)
Posted 22 Jul 2015 by Profile Teemu Mannermaa
It's been a week, can we get an update?

Dnet volunteer staff was working on the keymaster hardware issue and they managed to get it back alive, at least temporarily pending further hardware replacements. Sounds like there was at least a fried memory module that brought keymaster down.

I'm just starting the work generators to get fresh work out there. Also I'm bumping our buffer levels a bit. :)

Looks like others answered the other questions raised here, thanks for those!

Hey, I like to join in whining! I love to whine. Not so much winning, though.

17) Message boards : News : Out of work (Message 6648)
Posted 12 Jul 2015 by Profile Teemu Mannermaa
There's no more work available at the moment due to the keymaster hardware failure. Our local cache was just also depleted, which lasted for about two days. So let's finish what we have and then move on to backup projects (yes, they are always good idea to have) while we wait for the staff to repair keymaster. Rest assured, they are working hard to get the keymaster back up. As soon as that happens, we'll get fresh work out for our hungry systems to crunch.

For more details and latest developments, please read Thanks for your patience!
18) Message boards : Number crunching : Moo use my intel gpu, not my amd gpu (Message 6646)
Posted 11 Jul 2015 by Profile Teemu Mannermaa

I made an explanation of what's going on here at post At least the problem is clear (miscommunication between BOINC and Dnet Client we use for actual crunching) but fixing it might get tricky.

19) Message boards : Number crunching : Nvidia GPU workunits won't start (Message 6645)
Posted 11 Jul 2015 by Profile Teemu Mannermaa
The application is trying to use my Intel GPU instead of NVidia GPUs.

Aha! Thanks for this information, at least now we know what the problem is. Although, the fix for this might be a bit involved. Meanwhile, I'll probably try and get newer CUDA builds with our new app for Windows build and deployed as those will use 1 device at a time and won't suffer from the scheduling problem.

This stems from the two different views on the OpenCL devices on the system. BOINC only sees the nVidia devices while Client sees all the OpenCL capable devices and thus device 0 is different. :(

Posted 10 Jul 2015 by Profile Teemu Mannermaa
After a few seconds of running the task progress bar stops at 17.567% and no further progress is made..

Oh no. :( Can you find the stderr.log file in the slot directory from a task that's stuck and post it either here or PM it to me? (Note that the log file might contain your ID which you might not want to disclose publicly.)
