Thanks. I thought general list is about gromacs/molecular logistics.

 The message says it all: double precision with GPU is not supported. There's almost no reason to use double precision for normal MD.

Hi,With 2019.4 version, I get this error
CMake Error at cmake/gmxManageGPU.cmake:50 (message):
  GPU acceleration is not available in double precision!


in spite that I have specified these options:

cmake .. -DGMX_GPU=on -DGMX_BUILD_OWN_FFTW=ON -DGMX_CUDA_TARGET_SM=52 -DGMX_DOUBLE=on


The device is M2000. Is that normal?
