Do you mean that you reconfigured without MPI and with CUDA? You don't need to uninstall anything to enable/disable configuration options, just clean your build directory and rerun CMake in it. > > > Can cygwin recognize the CUDA installed in win 7? if so, how do i link them ? Good question, I've no idea whether it can as I myself have never built GROMACS with CUDA on cygwin neither have I heard of anyone else do that. What I can safely state is that the native Win builds with non-cygwin CMake and MSVC as a compiler do work with with a variety of generators: nmake, ninja, and VS. However, it would be very useful to know whether/how it is possible to detect CUDA with CMake a build GROMACS with GPU acceleration on cygwin. Perhaps someone else on the list with more cygwin experience could help out with tips or even try to build with CUDA. > > > The default installation path of CUDA in win 7 could be C:\Program > Files\NVIDIA GPU Computing Toolkit\CUDA > > > If I am correct, it should be like > > > cmake .. -DGMX_GPU=ON -DCUDA_TOOLKIT_ROOT_DIR=C:\Program Files\NVIDIA GPU > Computing Toolkit\CUDA The whitespaces will need special treatment, AFAIR putting quotes around the path (or simply copying the directory to C:\CUDA) should work. Alternatively, you could try to put nvcc in your path, than CMake should be able to do the path handling magic. > > > Kindly give me your suggestion.
