This work unit stalled as soon as it had a lock on the GPU, which it ran to ~100% capacity. The GPU continued to be utilized and a shutdown of the system stalled for more than 30 minutes, at which time it was hard reset. The work unit had to be dumped manually before folding could resume. The system is a stock CentOS 8.3 desktop running kernel 4.18.0-240.1.1.el8_3.x86_64 and libopencl-amdgpu-pro.x86_64 19.50. Both newer kernels and newer amdgpu-pro have resulted in complete failure to run Folding@home on this hardware. Other work units from project 17435 and its series have demonstrated similar behavior. What can be done to guard against a work unit that misbehaves so badly as to consume 100% GPU - without doing any real work - while preventing a system from shutting down?

viewtopic.php?f=108&t=36871#p349658

Show us the log of what conditions led to 100% utilization with with zero progress after a day. Something is seriously wrong and we want to prevent that from happening to others.

No one seems bothered by the fact that what I just described is the behavior of malware: a program entices a user to run it with the promise of some benefit but, when run, it consumes system resources without providing the purported benefit and, instead, causes undesired system behavior. I am bothered by the prospect of the assignment servers returning malware to my system, so I have split each slot into its own running FAHClient instance and set up a systemd until to run the following script:

If anyone has a solution that isn't so blunt, especially if it saves me from an unnecessary download, I would be glad to try it out.

I've been getting some WUs of the same project on my RX 480 lately. They seem to hit the GPU hard [99% Usage, not typical of the RX 480] and the have a long TPF of 5mins10secs. They have bumped my PPD to +20% levels, around 500K.

I highly doubt the servers have anything to do with the issues. If FAH servers were feeding us malware I'm sure the folding base would diminish quickly. With so many various types of hardware that can be used for folding, they can't guarantee stability in all systems, but they certainly aren't the cause of system issues either. I'm folding on a very limited resource APU, and it has done 50+ work units in that series with no issues and 100% completion rate. On this system, the vast majority of work units will push the GPU to 100%, so there is no change there.

I run a simple windows system, so I can't help you with software. But often the details of drivers, versions, updates, etc all come into the picture when folding, especially if it's an instance where there are often a lot of versions floating around and still in use. There were offers of help in the previous thread you linked, but you didn't have the information they needed to help. But I agree.... if you have a system that won't run work units properly the issue is with the system and that should be priority over protecting the system to make it easier to dump work units.

It seems you are running a rather unconventional setup, so for that reason the amount of help people might be able to provide is likely limited. Running multiple instances of the client is likely just making things harder IMHO. On my system the only time I've had any stability problems was when I realized that most benchmark/testing hardware will allow some instability if you push overclocks too far, where FAH will find those flaws quicker. Any needs to pause, finish, restart, or resume slots works every time without issue.

A Threadripper with dual Vega 64 running CentOS is hardly unconventional for a folding system. I just want to track down the cause of the problem my system has with specific work units. Since I have not been able to do that and I have not received any constructive guidance on where to begin, I resorted to this convoluted multi-client hack that, frankly, was not worth the amount of time I put into it. In fact, I have dedicated far too much of my time to trying to run a stable folding system over the past year since it was decided that a working OpenCL implementation is not sufficient to allow a system to fold. Instead, it is up to the broken OpenCL detection of the client to decide if the system can fold, regardless of how well the cores that do that actual work are able to run on the system's OpenCL. Before that change, when I had an OpenCL implementation that ran well on my system despite FAHClient not detecting it, my system was rock solid and had to dump very few work units, none of which had to be dumped manually. Since that change, I have not been able to find a version of OpenCL that is both stable and visible to FAHClient and I just want to find a solution to that artificially crafted problem.
