BAD_WORK_UNIT (114 = 0x72) on AMD Radeon RX 5500 XT

PostPosted: Sat May 02, 2020 4:01 pm

Hi everyone,

I have problems getting my GPU to fold.

After installing the fahclient 7.6.9 the GPU slot seemed to fold fine. After some days the GPU slot seems to be "broken". Everytime a new WU is downloaded, the GPU slot starts folding but immediately stops at 0% with the warning "Error initializing context: clGetDeviceIDs (-1)" and "BAD_WORK_UNIT (114 = 0x72)" in the log. After 10 or something retries the slot shows "Failed" in fahcontrol.

I am on Linux Mint v19.3, fahclient v7.6.9 with the newest Radeon drivers v20.10 from amd-dot-com/de/support/graphics/amd-radeon-5500-series/amd-radeon-rx-5500-series/amd-radeon-rx-5500-xt

Does anyone know what's going on here and how to fix the problem?

Any help is appreciated.

Some more details to come:

Welcome to the F@H Forum 4n0n,

I have read somewhere on the Forum that the latest AMD Drivers have removed OpenCL support from some old GPU models which are supported. The "fix" was to use a previous version of the drivers. By chance, was there a recent driver update which you can revert and check to see if it resolves your problem or not?

Or a recent update broke a link to the necessary OpenCL libraries. The RX 5500 is recent enough that it should still have OpenCL support in the drivers from AMD, however I don't know whether the package downloaded from AMD includes that support or if you also need to install a package with matching OpenCL support. You may also need to install the OpenCL-dev package.

Thanks, PantherX for your reply. In fact this is indeed the solution for my problem. In the meantime i figured out the following:

1. The root cause is the way, FAHClient spawns its child processes on linux. In consequence they have not the sufficient privileges to access the resources (OpenCL) required for GPU processing (see https://github.com/FoldingAtHome/fah-issues/issues/1418 for details). So a real "solution" can only be done by the devs fixing the bug in FAHClient.

2. There exist two conceptually different workarounds for the problem:

a) change the user, the FAClient runs with from "fahclient" to "root" as noted here: viewtopic.php?f=74&t=31096#p303883
Therefor the file /etc/init.d/FAHClient needs to be changed. The line
Code: Select all
USER=fahclient
needs to be changed to
Code: Select all
USER=root

Attention: This workaround might put your system at risk. Running jobs as "root" normally is a bad idea.

b) creating a systemd Service for starting FAHClient
This approach is described here: viewtopic.php?f=81&t=33353
For what I know, this has no security impact to your system and thus is the preferred method for me.
