Message 1997071 - Posted: 6 Jun 2019, 18:50:17 UTC

I have noticed that WUs starting with numbers like 15fe, 15ap, 12jl and 12mr run for about 15 seconds and then are postponed on my t1700 machine. The WUs starting with blc26 run all the way to completion. I have had to suspend those postponed task to get a blc26 WU to start.

The computer is running Ubuntu 18.04.2 LTS (4.15.0-51-generic) and I am using the Beta SOG app for the GPU's.

The only thing I changed was going from 50% to 25% CPU use through Boinc Manager. I have subsequently changed it back to 50% and restarted BOINC but no dice.

Anyone have any ideas how to fix this?

Message 1997080 - Posted: 6 Jun 2019, 19:33:51 UTC

My guess is the compute kernel primitives are corrupted. I would exit BOINC and delete all the files in the ComputeCache folder and then restart BOINC. The ComputeCache is here in Ubuntu 18.04.

/home/{username}/.nv/ComputeCache

The .nv directory is a hidden directory. You can view it by turning on Show Hidden Files in the File Manager hamburger menu.

The gpu app will recreate all the primitives once it starts crunching again and that should clear up the too many exits.

I deleted all files and folders in ComputeCache folder and the postponing problem still persists. BTW the ComputeCache folder was here: /var/lib/boinc-client/.nv/ and not in the home directory. The contents of the ComputeCache folder:

/var/lib/boinc-client/.nv/ComputeCache# ls
0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f  index


Also this is a headless system so I have to ssh into the computer using the terminal.

OK, didn't know you were running the repo client or were headless. Reinstall the graphics drivers if deleting the compute cache didn't work.

Ok. I upgraded from 390 to 430 (I probably should have just reinstalled 390) and when I restarted boinc I got a missing .cl file error. I aborted the WUs and of course I am in the penalty box. I will keep you updated when I get some GPU WUs.

Shouldn't have aborted, just stopped BOINC and installed the OpenCL drivers. For some reason, some people don't get the full meta package of the new drivers that is missing the OpenCL components. All you have to do is install them with:

sudo apt-get install ocl-icd-libopencl1

Since I hate dumping work because of a simple oversight, I always run clinfo after any changes to the system to verify both the CUDA and OpenCL drivers are present before I fire up BOINC.

I tiried to install it and it came back I already have the newest version. I must have gotten it when I installed 430.
I installed clinfo.

Meanwhile I am still in the penalty box...

So what does the output of clinfo show for your OpenCL driver component? Look at the end of the output in the Terminal window for the status of OpenCL.

I got it fixed. The t1700 is crunching away on its GPUs

I changed to this special app: MBv8_8.23r3602_sse2_clNV_SoG_x86_64-pc-linux-gnu

and added this file: MultiBeam_Kernels_r3602.cl to the /var/lib/boinc-client/projects/setiathome.berkeley.edu folder

Thanks for the help

Didn't realize you had the CUDA toolkit installed. That was probably the problem. The toolkit installs its own files and drivers outside of the normal downloaded versions in a different location.

No the CUDA toolkit is not necessary to crunch. All that is needed is the manufacturer drivers with both the CUDA and OpenCL components.
The CUDA toolkit installs its own driver versions that is normally not the same as the current manufacturer driver version unless you specifically tell the toolkit installer NOT to install the toolkit driver and keep the manufacturer drivers. The toolkit drivers get installed into a different location from the normal manufacturer drivers. They also change the Path and LD Library paths and environment variables.
Likely the reason why even after you installed the OpenCL library separately they were not found.

Message 2003298 - Posted: 19 Jul 2019, 17:56:34 UTC

I have this same problem. Just started on a new 18.04 system I put together yesterday. I googled around and found several of the "postponed for 30 seconds" problems but no solutions seems to work and I probably need to enable some log flags to get more info about that is happening.

Ati drivers were installed from amdgpu-pro-19.10-785425-ubuntu-18.04.tar
using
sudo ./amdgpu-install --OpenCL=legacy

WCG tasks run fine but gpu tasks have problems:
all milkway error out (no 30 second stuff)

all setiathome run 2 seconds and generate that 30 second error message

Going to post this over at boinc questions also. This is the first Linux system I have built that uses those S9000 "pro" AMD cards.
I noticed that "amdgpu-pro-install" is just a link to amdgpu-install so there is no longer any specific "pro" driver from AMD for Linux unlike windows..

Plugged directly into the MB or on Riser cards?

When the riser card stuff is not quite right. It postpones but then the gpu tasks are "waiting". Because it starts another up. So it generates a LOT of gpu tasks waiting. This doesn't exactly sound like your symptoms though.

I just checked that and the risers are locked into position correctly.

I had actually damaged an RX570 by not watching how the riser fit it in and have been careful ever since. While there are fusers for the 12v line there are none for the 3.3 and while there is no obvious damage on the PCB the lights blink and the fans spin but board never worked again.

Unfortunately, I have had to resort to "unplug/plugin again" as well as replacing (if that is what you are using) the USB cables with higher grade Ugreen data transfer 3.0 cables.
