A first step is to type "nvidia-smi" at a terminal prompt, and see if it
finds all your hardware correctly.

If that works, we need to determine if the error is generic, or specific
to your particular system. Please go to AMBERHOME and type "make
test.cuda.serial" and see what happens. If you get "nonsupported HW on
every test" (as I suspect you will), then something has gone wrong with at
least the cuda install.

...good luck...dac
