Hi Francesco,
There are two things for QE-GPU,
1) Hardware, the Maxwell GPU is not recommended for QE since its double
precision is very slow. You shall look for Fermi (C207X) or Kepler
(Titan Black/Z, K40/80) cards for QE-GPU computation.
2) Software, cuda-6.5 works okay for QE-GPU v.530 on my servers and I
think it should also work for v.540. I also used Intel complier to do
compile QE-GPU.
Here are my config input,
./configure CC=icc F90=ifort F77=ifort MPIF90=mpiifort \
--enable-parallel --disable-openmp --without-scalapack \
--enable-cuda --with-gpu-arch=sm_20 --with-cuda-dir=/usr/local/cuda-6.5 \
--with-magma --with-phigemm --with-pinned-mem \
LDFLAGS="-L/usr/lib64/ -lstdc++"
Then you can follow the steps in Filippo's webpage,
https://github.com/fspiga/QE-GPU
Hope it helps,
Rolly

Hi dear Users,
I am trying to install and run jobs on the GPU I have, a gtx 980 Ti
nVidia.
I followed the official git web page to intall the GPU version. But
after several fails and a couple if days trying to solve. I ask for
help now.
The configuration seems to go well. The make command doesn't run
properly since is not finding some "ELPA/src" folder and not
installing PhiGemm and probably also magma is not getting installed.
I am not sure If it is legitimate to ask here for that help.
But I bet someone before tryed and may solved my problems already.
The System is Ubuntu 15.04 since the installation of Cudatoolkit is
smooth.
Nvidia drivers are 352 since are the latest supported in 15.04.
Cudatoolkit 7.5. Computing capacity of the nvidia graphic card is 5.2.
Could it be that the architeture sm_35 is not appropriate for a
Maxwell GPU? What about using the TITAN X. I read someone did...How?
Here attached:
- the command I used in cmd.txt file
- the configure output in conf.txt
- the make output in make.txt
- the error raised from make command in Error_make.txt
Please let me know if I am doing something wrong
Thank you very much
