Re: [Pw_forum] QE-GPU problems.

Hello, Well, my card is actually GTX1060 but I didn't bought it especially for calculations. Just from my built-in curiosity, and I know the game is not worth the candle, I want try to run it anyway and close that 'chapter' of my life :) I will post here some tests results - as I was

Hi Konrad, Nvidia GTX 1060 is sm_61 and per https://github.com/fspiga/QE-GPU, it supports up to sm_60, based on my experience QE-GPU will compile with sm_61 however when you run pw-gpu.x it will throw errors, hence there should be a slight modification on the QE-GPU source code to include sm_61,

Re: [Pw_forum] QE-GPU problems.

Hi Konrad, My experience with QE-GPU is that it works only with double precision supported GPUs but not single precision. I am using TitanZ and Intel compiler, it works fast. Here is my ./configure ./configure CC=icc F90=ifort F77=ifort MPIF90=mpiifort --enable-parallel --disable-openmp

[Pw_forum] QE-GPU problems.

Deer community, 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. 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
