After much reading I setup a symlink for libOpenCL.so to var/lib and var/lib/X86_64-linux-gnu

with no luck

I am not sure why it is mentioning ATI as well as NVIDIA.

I also checked CL info:

$ clinfo

Number of platforms: 0


I guess this has just taught us, if you want to run GPUs, better to stick to Windows than Linux!

We have moved all our systems over to Linux Mint (64 bit) but found the default Nvidia installer did not seem to work very well.

Normally (when running Windows) we would have both OpenCL and CUDA libraries however looking at EventManger I think that perhaps only CUDA is installed?

However looking at the Collatz Linux Apps I can see that they are called:

1.40 (opencl_nvidia)

https://boinc.thesonntags.com/collatz/apps.php

So does mean that we will not get any work units sent to these machines due to a possible lack of OpenCL installed?

This host with the 1080Ti's has been trying to get Collatz work now for over 2 hours, but just keeps getting the following message in EventManager:

Mon 10 Dec 2018 16:12:19 GMT | collatz | Sending scheduler request: Requested by user.
Mon 10 Dec 2018 16:12:19 GMT | collatz | Requesting new tasks for NVIDIA GPU
Mon 10 Dec 2018 16:12:20 GMT | collatz | Scheduler request completed: got 0 new tasks

Thanks for any help in this matter
