Dear Uri,<br>
<br>
from the error message I believe the memory of your GPU is simply
not capable enough to run such simulation.<br>
Indeed, it fails during an operation of allocation on the GPU
memory.<br>
<br>
Kind Regards,<br>
<br>

<div class="gmail_extra">Hi again Mr. Spiga, thanks for the
reply.<br>
<br>
I was able to compile with your help. What I did was:<br>
<br>
1. configure the main QE 5.1 with --enable-openmp and
--disable-parallel.<br>
2. make all the QE 5.1<br>
3. recompile BLAS with -fPIC<br>
4. configure the GPU (from the git master branch) with
--enable-openmp --disable-parallel --enable-cuda
--with-gpu-arch=sm_30 --with-cuda-dir=/usr/local/cuda-6.5
--with-phigemm --without-magma<br>
5. and make -f Makefile.gpu all-gpu<br>
<br>
When i try to run pw-gpu, ph-gpu or neb-gpu I get the
following error:<br>
<br>
[<a moz-do-not-send="true"
href="http://vloc_psi_k_cuda_v1.cu:171">vloc_psi_k_cuda_v1.cu:171</a>]
Allocation of GPU resources for the plan failed! Program
exits... <br>
Error condition encountered during test: exit status = 1<br>
<br>
The cp-gpu is working. I checked during the run with
nvidia-smi and it was using the GPU. Also the samples which
come with CUDA work.<br>
<br>
Maybe you have an idea about this error.<br>
<br>
Thanks in advance and have a nice holiday,<br>

Ok, that missing flag is a case the configure should
handle. I will fix this. I have no machine with GCC 4.8, I
have to upgrade one and do some testing.<br>
<br>
About "pw.x" or "neb.x", QE-GPU makefile does not create
them. If you need the CPU-only executable first run the QE
configure in a "standard way" then run the QE-GPU one. In
this way you get both type of executable (but yes, you
need to do twice the procedure).<br>
<br>
Speaking about ph-gpu.x, this is a problem that has been
already fixed in the git master branch. Try to checkout
the latest git version of QE-GPU or please wait me to
finalize a new QE-GPU version. As this point, without
pushing too much in release new functionalities, I can
create just one new minor version with a few important bug
fixes related to the configure and makefile.<br>
