"ac_rtld error: shdr->sh_size & 3 ELF error: invalid section index" on Linux OpenGL Mesa

Topic 221520
(moderation:
On my Debian system with a Radeon 590, using Clover OpenGL provided by mesa, all WU assigned to the gpu fail with a Computation error. PRIMEGRID and Amicable Nubmers are the other projects that I've been able to confirm working.

As a long term user of multiple AMD GPUs at this project, the Clover OpenCL implementation doesn't work here, unfortunately. You need the proprietary implementation contained in the "Radeon Software for Linux" package, formerly known as AMDGPU-PRO.
I don't even use one of the supported distros (Red Hat, Ubuntu, OpenSUSE) so I extract the OpenCL bits from the full Red Hat package, since my distro is RPM based. I don't know the situation with Debian but if someone has repackaged AMDGPU-PRO to work with Debian, maybe that's what you need. I have lots of Polaris series GPUs from RX460 to RX580 and they work very well for me with the extracted bits from the Red Hat package.
Cheers,

I'm a little confused with the discussion bouncing between OpenGL and OpenCL, but I'll assume that all that you want is to have OpenCL working to get E@H crunching. As the others have said, get the AMD driver stack (from https://www.amd.com/en/support). The included documentation will instruct how to install OpenCl from an install script.
In brief, the command line, from within the extracted stack directory (e.g. amdgpu-pro-19.50-967956-ubuntu-18.04), will be,
$ ./amdgpu-pro-install -y --opencl=legacy --headlessthen reboot.
This will install:
Only base kernel
Pro OpenCL (headless mode)
If the --headless option is omitted, then these components will be installed:
Base kernel
Accelerated graphics
Mesa multimedia
Pro OpenGL
Pro Vulkan
Pro OpenCL
I always install it on my Ubuntu systems using the --headless option.
In either case, before running the script, I'd recommend shutting down BOINC.
This previous discussion forum may also be of help.
Ideas are not fixed, nor should they be; we live in model-dependent reality.

Mesa, also called Mesa3D and The Mesa 3D Graphics Library, is an open source software implementation of OpenGL, Vulkan, and other graphics API specifications. Mesa also contains an OpenCL implementation which goes by the name of 'Clover'. The OP did refer to 'Clover OpenGL' but I assumed that was just a typo or perhaps a misunderstanding. The message I wanted to convey was that people have had problems trying to use the OpenCL implementation that comes with Mesa.
Of course, if Clover is being actively developed (I don't know the status of that) it could well be that at some point Einstein apps might start working with a new version of Mesa/Clover.
Since Ubuntu is a Debian derivative, maybe a package designed for Ubuntu could be used to provide the PRO OpenCL for Debian. I suspect maybe not directly without some creative modifications to the install script :-). I would guess it's more likely that someone has already created a package tailored to Debian - so no mods needed to install it successfully.
Cheers,
Gary.
