Hello, new user here just trying to sort out GPU compute on my machine.

Long story short, I installed =dev-libs/rocm-opencl-runtime-3.1.0 and its dependencies, as well as dev-util/{cl,rocm}info. Two of the packages for dev-libs/rocm-opencl-runtime have USE flags (just one relevant one apiece):

=media-libs/mesa-20.0.1-r1 has the "opencl" USE flag
=dev-libs/rocr-runtime-3.1.0 has the "nonfree" USE flag, which pulls in dev-libs/hsa-ext-rocr, described as "Proprietary image-support library for Radeon Open Compute."

I haven't been able to get rocr-runtime installed with the "nonfree" USE flag, so I suppose it's not entirely relevant. So, onto the main point. I have installed Mesa with and without the "opencl" flag, and these are the results:

with OpenCL: clinfo segfaults when run (shows some GPU information then segfaults), rocminfo runs fine (shows all GPU information), and F@H recognizes my GPU (caveat: in the "OpenCL Device" section for it it says, "Bus:NA Slot:NA,") but fails to start using it saying, "Folding@home Core Shutdown: BAD_WORK_UNIT."
without OpenCL: clinfo runs fine (shows all GPU information), rocminfo runs fine (shows all GPU information), F@H no longer recognizes my GPU.

I'd like to contribute using my GPU, but I'm not sure at this point how to go about doing it.

Other information:

I have confirmed that other applications are able to use my GPU for compute purposes. I've tested this with the Collatz Conjecture project on BOINC. So I'm now really not sure what the issue is for F@H.

My understanding is that the GPU folding core does not work with the Mesa drivers, you need to use the AMD proprietary drivers.

Posted: **Tue Mar 24, 2020 5:14 am**

Oh, as in the closed-source OpenCL drivers? I believe those are available with dev-libs/amdgpu-pro-opencl, but I'm not sure.

Posted: **Tue Mar 24, 2020 6:06 am**

Well, I went and installed those (=dev-libs/amdgpu-pro-opencl-19.30.838629), and my card is now recognized properly in fah-control (I think). I now see "OpenCL Device 0 Platform:0 Device:0 Bus:1 Slot:0 Compute:1.2 Driver:2906.7" in the system info tab. Though now that I look a little closer, GPU 0 shows as bus 1 slot 0 and GPU 1 as bus 2 slot 0, but OpenCL devices 0 and 1 show as bus 1 slot 0. Regardless, I still get the "BAD_WORK_UNIT" error.

I'm not sure if it's something to do with the version of F@H in the Gentoo repo or what, but the things about libssl and libcrypto have been there since I first started using it.
Curiously, fah-control reports things slightly differently than FAHClient does:

Not certain of the name, but the AMD proprietary video drivers instead of Mesa. Depending on the Linux distro, a depository may have them in a single package or split into drivers and OpenCL separately, or you would download them direct from AMD support.

The libssl and libcrypto messages are from the client using older versions than are the default in recent versions of Linux. Some workarounds have been posted here and I understand on some other sites.

Well, if it's going to require completely redoing my graphics stack, I don't think I'm going to put the effort in. It would be a lot of work for me to redo the whole graphics stack in my system just for this, especially since it's not officially supported by the distribution I prefer to use. So I'll probably end up finding some other project to try and contribute to in a similar capacity.

Thank you for your time.

Er so as I was cleaning things up I took a look at some files I'd just sort of glossed over previously, and came across the executable to start F@H. I decided I was curious enough to play with it a bit more, so I ran it manually with a high verbosity setting and came across this in /opt/foldingathome/work/o1/wuresults_01.dat:

The "Checking core state against reference..." caught my attention, so I rebuilt Mesa with the "opencl" flag and ran F@H again and found that the same thing happens. It seems to me that something in F@H isn't getting the core state correctly, since that's exactly where it fails regardless of Mesa OpenCL support or what options I pass in when running the command manually. Mesa added in its own OpenCL platform when compiled with support for it, but regardless of Mesa's support there was always:

Code: Select all

[1] compatible platform(s):
  -- 0 --
  PROFILE = FULL_PROFILE
  VERSION = OpenCL 2.0 AMD-APP.internal (3084.0)
  NAME = AMD Accelerated Parallel Processing
  VENDOR = Advanced Micro Devices, Inc.

(1) device(s) found on platform 0:
  -- 0 --
  DEVICE_NAME = gfx803
  DEVICE_VENDOR = Advanced Micro Devices, Inc.
  DEVICE_VERSION = OpenCL 1.2

I've tried targeting that, and the output of doing so is what you see in the first code block. I'm not sure whether calling it a bug or failed implementation of core state checking in F@H is a bit presumptuous of me, but at first blush that seems to be the issue. Either that, or it could be a slight misconfiguration of my kernel, but I don't think it is, since none of the ROCm packages complain anymore about incorrectly set kernel flags.
