Is there no OpenCL support available for that platform? If it is,
install that, re-configure, re-build.
If it really only has CUDA, unfortunately we dropped support for that
three years ago. You can checkout the CUDA "branch" from GitHub to get
the last Jumbo code that had CUDA, but there were few formats and they
were not very optimized, no auto-tuning and so on.
