Description Vedran Miletić 2017-02-10 17:51:57 UTC
Octopus is a quantum chemistry code with experimental OpenCL support using clBLAS and clFFT [1]. It can be compiled with:

$ ./configure --with-libxc-include=/usr/lib64/gfortran/modules --enable-opencl --with-clblas-prefix=/usr/local --with-clfft-prefix=/usr/local

Running test file named inp from http://octopus-code.org/wiki/Tutorial:Hydrogen_atom results in:

AN INTERNAL KERNEL BUILD ERROR OCCURRED!
device name = AMD FIJI (DRM 3.8.0 / 4.9.7-201.fc25.x86_64, LLVM 5.0.0)
