In Debian we moved src:nvidia-settings to main and build libxnvctrl0 on all platforms ...

I'll probably upload 7.5 to experimental/NEW tonight. Andreas

You mean nvidia-settings doesn't sound that useful without Xorg driver? Quite possibly, but libxnvctrl0 is built by the nvidia-settings source, maybe that might be useful? pycuda failed with 'cannot find -lcuda', probably due to missing libcuda1 Is that a nvcc or a gcc command failing? nvcc should be able to resolve -lcuda via the stub (the corresponding -L... are set in nvcc.profile, but I haven't tested this (w/o libcuda1)). I think it's gcc, the build log is here: https://launchpad.net/~ginggs/+archive/ubuntu/testing/+build/9316956/+files/buildlog_ubuntu-xenial-ppc64el.pycuda_2015.1.3-1build3~ppa3_BUILDING.txt.gz

In Ubuntu on ppc64el: eztrace-contrib built without changes hwloc-contrib built without changes, after building nvidia-settings for ppc64el starpu-contrib built after enabling Architecture: any pycuda failed with 'cannot find -lcuda', probably due to missing libcuda1

I tried the cuda code samples (see README.Debian), and most built (only those few that link with -lcudadevrt seem to miss a -lcudart). I didn't try to actually run even one of them :-) I built 7.5.18-1 r6291 in an Ubuntu PPA. I was able to build the reverse-dependencies eztrace-contrib, hwloc-contrib and pycuda without modification. A local build of pycuda on Ubuntu Xenial failed with the following error, but it probably just picked up something else installed: error: Cython does not appear to be installed I tried a couple of the pycuda examples and they ran successfully, but the script to download more examples from the wiki didn't seem to work any more. Ubuntu has starpu-contrib 1.1.5-0. It build successfully after I changed CONTRIB_GCC_VERSION := 5 and adjusted the build-dependencies. I did not try building with CONTRIB_GCC_VERSION := 4.9. Looking at ppc64el now ... For Ubuntu, I think I will use the no-libcuda1 virtual package for ppc64el. I don't think a Tesla driver package for ppc64el will be uploaded in time for the Xenial release.

I tried the cuda code samples (see README.Debian), and most built (only those few that link with -lcudadevrt seem to miss a -lcudart). I didn't try to actually run even one of them :-) What's the status of using CUDA 7.5 with GCC 6 (already in experimental)? Right now I blocked this version in the header check and the gcc/g++ wrappers also ignore that version, so you need to ensure you are really testing with g++-6. If it doesn't blow up, we should enable it as well. Looking at ppc64el now ... Andreas

Hi anbe, Is there something that I can help? Besides please ping me if the svn repo is ready, I can conduct some test and check :-) Thanks. -- .''`. : :' : `. `' `-
