= Introduction =
I have tested the GPU enabled version of AMCL (avialable at http://developer.amd.com/gpu/acmlgpu/Pages/default.aspx).
I have tested it on HD4780 with Ubuntu 8.04 LTS. We need to install gfortran version 4.1.2. It only works with thi paticular verison. There are two versions of gfortran available on Ubuntu 8.04 LTS. The latest package is "gfortran-4.2"
but this is not work with the AMCL-GPU. Please install the package "gfortran-4.1" explicitly when you try.
