<div>Dear Forum - Members,<br></div><br>I request your help with the following error, whereas running pw.x in the gpu-version of QE:<br><br>---------<br>[NEWD] Problem don't fit in GPU memory, memory requested ( 10322157 ) > memory allocated (0 )!!!<br>
[VLOC_PSI_K] Problem don't fit in GPU memory --- memory requested ( 75950756 ) > memory allocated (0 )!!!<br>----------<br clear="all"><div><div><br></div><div>We understand that this is a problem with the amount of memory, we know that we have to modify the file: "cuda_env.h", changing the flag in this file:<br>
<br>#if defined __CUDA_GET_MEM_HACK<br>#define __GPU_MEM_AMOUNT_HACK__<br>#endif<br><br><br></div><div>How can we assign the amount of memory by hand in this flag?<br></div></div></div></blockquote><div><br></div></div>Easy answer: you need to specify the amount of memory in byte. </div>
<div><br></div><div>Complicated answer: your machine or your software environment has something wrong and putting a number in cuda_env.h will probably produce a crash. </div><div><br></div><div>I already exchanged one or two emails with Jarol, he should be aware that I have already suggested that the problem might be your system and not the code. Anyway this "hack" has been deprecated in the 5.0.x. First I strongly suggest you to move to 5.0.x if possible. Based on the information you provide in the email I cannot guess why this happen. That "0" is the amount of free memory on the GPU card detected at runtime by a specific CUDA call. If it return zero there might be several reasons. </div>
<div><br></div><div>- check that where you compile the CUDA driver in installed (not only the toolkit, also the CUDA driver)</div><div>- check that the GPU is visible and works correctly (by running one or two examples provided by the CUDA toolkit)</div>
<div>- check that the GPU is in shared mode (using nvidia-smi)</div><div>- check that CUDA is linked properly to the executable and the environment is correct (I can do that if you provide the config.log)</div><div>- be sure to use the latest CUDA driver and toolkit PLUS the latest version of QE-GPU</div>
<div><br></div><div>Hope this help</div><div><br></div><div>Filippo</div><br><div>
