           Summary: Make Octopus OpenCL support work on Clover and
                    RadeonSI
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org

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:
