Hi,

Here is a contribution for the notes about finding the GPU.

I have a Radeon AMD/ATI GPU and have been crunching happily with POEM, Einstein and SETI.

Before the release of 16.04 (Long Term Release),
Ubuntu handed out an 'fglrx driver that had OpenCL.
sudo apt-get install fglrx-updates

also, explicitly setting the Xhost for BOINC was neededfor Ubuntu 15.10
xhost +si:localuser:boinc

A reference about what makes getting OpenCL complicated is at
http://lists.debian.org/debian-devel/2012/06/msg01108.html but this is probably outdated, now.


In the past there was a problem with what was installed and what BOINC looked for::
libOpenCL.so.1
and
libOpenCL.so

I fixed that manually.

But now, there is a problem.
Ubuntu has deprecated the fglrx driver.

In the past I had GREAT trouble getting the driver from AND to work.
Balancing compatible versions is not easy for me - and I tried hit & miss with a lot of scratch paper.
Things to balance
- opencl
- Xorg
- Mesa driver
- Linux kernel

I will try the contibuted code listed in the URL above and see if it works.

There is a post at Einstein here and a brief background here

If you are successful Jay please post your findings.

Good Luck.
