<p>Deer community,</p>
<p>Recently I'm trying to compile and run QE-GPU version on my new
Cuda capable card. Unfortunately after many attempts the result is
poor. <br>
</p>
<p>I have Nvidia GTX 1060 (with Pascal architecture, 1280 cuda
units). I've managed to compile GPU PWSCF with sm_60 (pascal)
support but when trying to run any calculation I get: <br>
</p>

<p>Program received signal SIGFPE: Floating-point exception -
erroneous arithmetic operation.Backtrace for this error: #0

<p>The configure options were: <br>
</p>
<p>./configure --enable-parallel --enable-cuda --enable-openmp
--with-cuda-dir=/usr/local/cuda-8.0/ --with-internal-blas
--with-internal-lapack --without-magma --with-phigemm
FFT_LIBS=/mnt/fast/fftw-3.3.4/.libs/libfftw3.a
--with-gpu-arch=pascal<br>
</p>
<p>For now I'm trapped here, not knowing what to do. Is it
possible to run QE-GPU not only on specialized computing devices
like e.g. K20 at all? How to manage this? <br>
