[Pw_forum] GPU Amount Memory
Dear Forum - Members, I request your help with the following error, whereas running pw.x in the gpu-version of QE: - [NEWD] Problem don't fit in GPU memory, memory requested ( 10322157 ) > memory allocated (0 )!!! [VLOC_PSI_K] Problem don't fit in GPU memory --- memory requested ( 75950756 ) > memory allocated (0 )!!! -- 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: #if defined __CUDA_GET_MEM_HACK #define __GPU_MEM_AMOUNT_HACK__ #endif How can we assign the amount of memory by hand in this flag? Thanks a lot.
