<div>I have finally got the GPU version of CP2K working. However when I run, I get the following warnings:</div><div>```</div><div> ELPA: Warning, CUDA kernel only works with block size 2^n (n = 1, 2, ..., 10)!<br> The compute kernel will be executed on CPUs!<br> We recommend changing the block size to 2^n</div><div>```</div><div><br></div><div>There have been discussions here: https://github.com/cp2k/cp2k/issues/464</div><div>I am not sure what was the outcome, but it does say certain commits for closing the issues.</div><div><br></div><div>1. How to define the block size?</div><div>2. What are other "good practices" for extracting the most out of GPU?</div><div><br></div><div>CP2K version: 2022.2</div><div>Configuration: --with-libxc=install --with-libint=install --with-fftw=install
--with-mkl=system --with-libxsmm=install --with-elpa=install --with-spla=install
--with-cosma=install <br><div><br></div><div>Thank you--with-intel=system --enable-cuda --gpu-ver=V100 --with-openmpi=system <br><br></div></div>
