My Win7 and ATI 7770 PCs are working fine with collatz.
However, my LM and ATI 7770 are not downloading.

Can someone please advise as to how I can fix this?

If additional info is needed, please advise and will provide.

Based on what it shows at: http://boinc.thesonntags.com/collatz/hosts_user.php?userid=53433 , neither of your Linux boxes show GPUs. My guess is that you need to restart BOINC after you start the computer.

I have this issue, and it seems to be common with Linux variants that the drivers load after BOINC starts, so it doesn't recognize that you even have a GPU. I am not sure how to restart BOINC on Mint, but I am guessing it may be
sudo /etc/init.d/boinc-client restart (this works for ubuntu).

See also: http://boinc.berkeley.edu/wiki/Stop_or_start_BOINC_daemon_after_boot

If you can't get it working, you may have to load the correct drivers. PM me if you can't get it going. I will be back this weekend.

Tried sudo /etc/init.d/boinc-client restart
No joy. The command ran, but WUs didn't start downloading.

I've left the PCs running in case the download is just slow.

Thanks for the try.

Have you trued this yet:

If you have problems with the BOINC client detecting GPUs on an Unbuntu system, try apt-get or synaptic installing "nvidia-modprobe" and then rebooting.
You might have to enable the unsupported/backports repository.

I read about it here:
http://www.gpugrid.net/forum_thread.php?id=3919#38872

I KNOW you said you have Mint and NOT Ubuntu, but it may work. I am NOT a Linux guy, so am extremely limited in my help.

Your GPUs are still not recognized. (They don't show up on your page at http://boinc.thesonntags.com/collatz/hosts_user.php?userid=53433 ) This means that either your computer is not recognizing the GPU, and if it is, you don't have the drivers installed.

I don't remember specifically what drivers I installed, but I know that I did install the latest from AMD:

Go to http://support.amd.com/en-us/kb-articles/Pages/OpenCL2-Driver.aspx

Look at your page above, and see that your windows GPUs are recognized, and that they are using OpenCL 1.02

I also recommend installing Catalyst from the same page.

I also installed AMDOverdriveCtl

See: http://sourceforge.net/projects/amdovdrvctrl/ This allows you to change the speed of the GPU and the memory, as well as set fanspeeds or make custom fan curves.

But, like I said in my earlier post, I have to restart boinc-client everytime I reboot after the drivers load. This is a known problem. So even after you have the CL drivers installed, it is almost certain that you will have to restart boinc every time you start the computer. I don't restart mine unless I upgrade the kernel, so it isn't really a nuisance for me.

Having a hard drive failure and reloading from scratch, I found that I had to use 14.04.2 not .3 in order for the drivers to load correctly. And I also had to issue the command:

cd /usr/lib/ && sudo ln -s libOpenCL.so.1 libOpenCL.so

in order to get openCL operating correctly. See http://boinc.berkeley.edu/dev/forum_thread.php?id=10454 for more information.

Depending upon the Linux distribution, some will add the OpenCL to the libpath while others require you to do it manually.

As far as starting automatically, Windows does it at login, not startup because the GPU apps require access to the GPU and running as a service doesn't allow that. Could that be the reason BOINC doesn't start automatically on Linux? I'm guessing it would need to be added to the .xinit or something like that so that it would start once the GUI launches.

I don't know if this is the only thing that got the Collatz Sieve to start downloading, but I had app_config.xml set to...

<app>
<name>collatz_sieve</name>
<max_concurrent>4</max_concurrent>
<gpu_versions>
<gpu_usage>0.25</gpu_usage>
<cpu_usage>0.25</cpu_usage>
</gpu_versions>
</app>

When I reset both to 0.50, the WUs started downloading. Also, I set the file to chmod 666 app_config.xml.

I have seen some scripts and ways to modify it on startup. I generally don't ever shut down the machines, so they run for months.. Being lazy, I just restart boinc after logging in and it works.

The sieve app will run at 100% GPU utilization with just one WU running at a time. Attempting to run 4 at a time will likely cause driver crashes due to lack of RAM. The old apps used maybe 40M of GPU RAM. The sieve apps use hundreds of megabytes (depends on your config) per WU so running 4 at a time could use 2GB GPU RAM.

If you have multiple GPUs installed, change the max_concurrent to the number of GPUs but leave the gpu_usage at 1.0.

<app>
<name>collatz_sieve</name>
<max_concurrent>1</max_concurrent>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>0.25</cpu_usage>
</gpu_versions>
</app>
