1) Message boards : Projects : Any projects supporting ppc64le Linux? (Message 109920)

I recently upgraded my desktop to a Power9 system from Raptor Computing, and noticed that none of the projects I ran supported this platform. Does anyone know of a project which does?

That's odd, since I did install the Nvidia OpenCL packages. Also, the project that uses the GPU uses CUDA, and is able to find the shared libraries:
einsteinbinary_BRP4G_1.39_x86_64-pc-linux-gnu__BRP4G-cuda32-nv270:
linux-vdso.so.1 => (0x00007fff44ef0000)

libcuda.so.1 => /usr/lib/x86_64-linux-gnu/libcuda.so.1 (0x00007f1cd6532000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f1cd6314000)

libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f1cd5320000)

I didn't think updating the packages would break anything. And they were kernel updates, not nvidia package updates. I am able to see that the card is present, drivers are loaded properly, and I can run CUDA applications.

I'm running Boinc 7.2.42, the latest version for Linux. The GPU was working, but I updated the CUDA & Nvidia packages with apt-get, restarted, now BOINC fails to recognise the GPU, citing error code 65280.

The GPUs work. CUDA-Z sees my GTX 690. The driver module is loaded:
$ ls /dev/nv*
/dev/nvidia0 /dev/nvidia1 /dev/nvidiactl /dev/nvidia-uvm

So why does BOINC's GPU support suck?
