Dear Filippo,

I am able to compile the pw-gpu.x finally and I am able to run all the 8x
C2050 GPU cards with the AUSURF112 benchmark. I have just aware that
although I have ifort, gfortran is also needed for the MAGMA package.

I found the performance enhancement is about 2.7 times comparing to 12 core
24 thread Xeon CPU cores.

I also found that other options such as cp-gpu.x were mentioned in the
Makefile.gpu, can I compile these files too?

Thank you so much!
