<div dir="ltr">Dear Eugenio,<div><br></div><div style>please subscribe the specific QE-GPU list here: <a href="http://qe-forge.org/mailman/listinfo/q-e-gpgpu">http://qe-forge.org/mailman/listinfo/q-e-gpgpu</a> ). I do not regularly look at the pw_forum ML so it is much better for all users to address their issues and questions to the other specific mailing-list.</div>
<div style><br></div><div style>Regarding your problem, I am assuming you are running on a workstation because despite you enabled both parallel and OpenMP you run your test using only 1 MPI process and 4 OpenMP threads. Ehm... wrong. If you are using a workstation with a single GPu there is no point to user --enable-parallel (and use one single MPi process). Please recompile your code disabling parallel (--disable-parallel) and run it in serial. When you fix this, if the problem persists try to disable MAGMA (--disable-magma).</div>
<div style><br></div><div style>An observation about your specific problem: you are running a NEB calculation on 2 images using 3 hydrogen atoms. This system is really small, I do not think you are going to exploit any interesting GPU acceleration running it.</div>
<div style><br></div><div style>One thing is not from you email: whatis the model of the GPU you are using? Is 20 the correct compute capability?</div><div style><br></div><div style>HTH</div><div style><br></div><div style>
