Well... I guess my AMD/ATI GPU may not be compatible with v1.18 since I am using amdgpu/pro with amd OpenCL...

It's probably also to do with the fact that GCN v1.0 and v1.1 (Southern Islands (SI) and Sea Islands (CIK)) GPUs are not yet fully supported by amdgpu.  It's still a work in progress but perhaps with kernel 4.19.x (due for release very shortly) those early versions of the GCN architecture will finally be fully supported.

I run 2 main classes of AMD GPUs under Linux.  One group are Pitcairn series (SI) eg. HD7850 and R7 370, which I deliberately run under the older fglrx driver which works just fine.  My distro (PCLinuxOS) is a rolling release and I maintain a full local copy of the repository.  That means I can always install and update to particular points in time.  All these machines are updated to mid 2016 when the appropriate versions of Xorg and fglrx were last available in the repo.

The other group are all Polaris GPUs with quite recent kernels (4.18.x) and the amdgpu kernel module.  On top of that I install the OpenCL libs from the Red Hat version (RPM) of what used to be called AMDGPU-PRO.  I started doing this with the 16.60 version by just selecting the small number of OpenCL related packages that were needed.  These days I'm up to the 18.30 version (the latest).  This also works just fine.

Periodically, I will take a machine with a HD7850 and install the latest kernel with the latest amdgpu kernel module and then install the latest set of OpenCL libs.  By using the appropriate SI and CIK kernel parameters everything boots nicely and clinfo seems to show everything in good order.  When I launch BOINC, the GPU and its OpenCL capabilities are correctly recognised and tasks are downloaded.  However, they crash after about 20 sec of run time.  So I put everything back to fglrx in that machine for the moment.

I don't know exactly where the problem is (I'm not a programmer) but I believe there is still something missing with the proper support of SI and CIK under the amdgpu kernel module.  My plan is to try again once 4.19.x becomes available - a week or two I believe.

 

Cheers,
Gary.

I already posted a support

I already posted a support ticket at AMD's community board and see what advice they could offer. So far, I have to *disable* the GPU support in Einstein@home's project preference so that no more GPU app will be downloaded. :-S

Searched Google and found old

Searched Google and found old articles in github.com which once some people reported the same issue for previous amdgpu/pro opencl stuffs.

Actually, it needs some environment variables to work properly.

1). Can add new script in /etc/profile.d/amdgpu.sh

export GPU_FORCE_64BIT_PTR=1
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export GPU_SINGLE_ALLOC_PERCENT=100
export GPU_MAX_HEAP_SIZE=100

2). Can modify /lib/systemd/system/boinc-client.service

[Service]
Environment=GPU_SINGLE_ALLOC_PERCENT=100
Environment=GPU_MAX_HEAP_SIZE=100
Environment=GPU_FORCE_64BIT_PTR=1
Environment=GPU_USE_SYNC_OBJECTS=1
Environment=GPU_MAX_ALLOC_PERCENT=100

ProtectHome=true
Type=simple
Nice=10
User=boinc
WorkingDirectory=/var/lib/boinc
ExecStart=/usr/bin/boinc --redirectio
ExecStop=/usr/bin/boinccmd --quit
ExecReload=/usr/bin/boinccmd --read_cc_config
ExecStopPost=/bin/rm -f lockfile
IOSchedulingClass=idle

Hope this helps others

Congratulations on getting your SI GPU working.  Would you happen to have a link to the information you mention, thanks?

In view of your success report, I booted one of my machines with an R7 370 (SI) GPU using the test OS install on a separate disk that I tried a month or two ago.  First of all I upgraded the install to the very latest kernel (4.18.16) and amdgpu module.  I also updated the OpenCL libs to the latest 18.30 version from the amdgpu-pro package from AMD.  The previous test I had done had used 18.20.

I launch BOINC (which resides in a subdir of my home directory) with my own launch script.  For a quick test, I just added the environment variables to the launch script, rather than edit a system file.  I added the exact variables as you have listed them above.  My launch script also sets LD_LIBRARY_PATH to allow BOINC to know where the OpenCL libs are installed.

As before, BOINC started fine and the event log showed the GPU being correctly detected.  I set a small work cache size and downloaded a couple of tasks.  They were set to crunch one at a time.  The first one launched, ran for about 15 seconds and then gave a computation error - the same result as when I last tried this test with the 4.18.2 kernel.

Do you know any reason why including the environment variables in the launch script wouldn't work just the same as putting them in the shell's startup files?

How is your Pitcairn GPU performing?  Are the tasks validating?  Have you tried running 2 concurrent tasks?  Would you mind sharing a link to the host ID so I can look for myself, thanks?

 For the moment, I've swapped the hard disk back to the old install with the fglrx driver and the machine is crunching again.  It only takes a minute or two to reboot with the alternate disk so I'm keen to try again if I can work out what the problem is.  A link to the information you found would be really helpful, thanks.

 

Cheers,
Gary.

By which user account you run

By which user account you run BOINC? boinc account? could you make sure that those 5 environment variables are correctly feed in with the that account and passed to amdgpu opencl run-time? by "sudo -E -u boinc xxx?" consider /etc/profile.d/boinc.sh ?

Try best to pass the variables first.

How about read this one?
