I used the GPUUG site to donate a hard drive a few months ago, but I never saw one get added to the donation purchases shipped page. Anyone know someone over there I can contact about that?

I can't seem to checkout a single branch these days without an unexpected disconnection. Anyone else able to complete full checkouts successfully?

Might be time to get this off of Berkley's hardware and onto hosts that donate hosting to open source projects like GitHub, GitLab, or Bitbucket
3) Message boards : Number crunching : Linux OpenCL Support ? (Message 2024789)

It's neat to see you managed to get the stock multibeam OpenCL app working with ROCm. The reason this doesn't happen automatically is that the the official SETI@Home plan classes that pick the apps for you are based on OpenCL and core driver versions that don't have any overlap with the versions reported by the ROCm OpenCL Runtime. Only the Astropulse app will automatically chose the ROCm OpenCL cards because of the flexible of version constraint in the opencl_ati_100 plan class the Astropulse OpenCL app uses.

You can see the beta plan_class_spec.xml here for the version constraints that have been preventing ROCm users from participating.

That is good info. Looks like fredi's computer 8867025 is running the PAL OpenCL driver for Linux (probably from the AMDGPU-Pro package). As ROCm driver cards still aren't chosen in the ATI multibeam client's plan class, the only results we'd get from those will be from anonymous hosts, and that's only when ROCm finally gets Navi support.

So the big question is how this continues to work on the macOS OpenCL runtime according to observations posted to this thread. My guesses are one of these:
- There's an issue with Navi support at the PAL layer. Both the Windows driver and AMDGPU-Pro use the PAL layer provided by device drivers.
- Both the Windows and AMDGPU-Pro OpenCL compilers are shipped with the same GCN bitcode mistakes.

I don't know if the Apple stack uses PAL at all.

Unfortunately, the stock multibeam client excludes the ROCm OpenCL runtime in its plan class at the moment, so you'd have to roll your own to use the card on ROCm.

Looks like I was in the same boat as most and just needed to enable vsyscall emulation. In newer kernels, it's disabled by default and there is no longer a native mode option. If you've opted to enable it via the Linux kernel command line (e.g. in grub) instead of compiling with the config flag, you can see if your current kernel was launched correctly with:
$ cat /proc/cmdline
BOOT_IMAGE=/kernel-genkernel-x86_64-5.3.8-gentoo root=UUID=abcdefg-1234-5678-fedc-ba9876543210 ro vsyscall=emulate


My strace output is not helpful as it doesn't show these old syscalls; it likely had nothing to do with that stat() line.

I just started seeing this after upgrading from Linux 5.0.0 to 5.3.8 and a glibc upgrade. Like with others, setiathome_8.05_i686-pc-linux-gnu and GPU runners work great but setiathome_8.00_x86_64-pc-linux-gnu gives the segfault and signal 11.

strace shows it happening after trying to stat init_data.xml (which doesn't exist in my stock project dir). Maybe stat-ing the missing file failed more gracefully in older kernels or older glibc?

With the exception of Astropulse, ATI/AMD OpenCL tasks are still not being sent to ROCm users. If there's anything we can do to help validate the platform so it can be made part of "the plan", let us know!

Noticed an APv7 workunit (3372198899) that no computers seem to agree on. Is there some aspect of the WU that makes it harder to gain consensus? Longer processing time? 0.5 rounding differences?

I'm in a dual-vendor card setup in Linux (computer 8678180). BOINC recognizes all my devices, I've enabled all the GPU+CPU types in my prefs, and have set use_all_gpus to 1 in cc_config.xml

I've yet to see a regular Seti@home task application use my AMD cards, only Astropulse. The nVidia cards get a mix of CUDA and OpenCL work and the CPU tends to be maxed out and happy.
