In this case nvcc will use the platform-default assumed to be in the path (e.g. clang), whenever possible the the build scripts will detect this and avoid passing this unsupported compiler to nvcc. When using a C++ compiler which is not officially supported by CUDA (e.g. This is becauise when the MPI compiler-wrapper approach is used, as nvcc can not reliably use compiler wrappers, the nvcc host compiler needs to be set manually. When configuring with both MPI and GPU support, the default CMake-based MPI detections should be preferred.

To manually set the nvcc compiler wrapper configure with passing the full path to a C++ compiler using CUDA_NVCC_HOST_COMPILER. Whenever considered safe, the build system will automatically pass the used C++ compiler for nvcc to be used as host-compiler. Note, that the NVIDIA GPU compiler (nvcc) requires a C++ compiler to compile host-code - the part of the code. If the CUDA toolkit is not installed in the default location ( /usr/local/cuda on Linux), its location needs to be specified using the CUDA_TOOLKIT_ROOT_DIR CMake variable. Native GPU acceleration $ cmake -DGMX_GPU=ON. Therefore, compiling without GPU acceleration is advised only in case if no compatible GPU is (planned to be) present in the system. Note that compiling with GPU acceleration does not produce a GPU-only mdrun, CPU or GPU acceleration for non-bonded calculation can be selected at run-time. The native GPU acceleration requires the NVIDIA CUDA toolkit and to run a comatible graphics card ( Fermi or Kepler series, compute capability >=2.0) has to be present in the system. OpenMP will work out of the box with any modern compiler (e.g. In GROMACS 4.6 the default configuration enables OpenMP and native GPU acceleration with CUDA. Substitute N with the number of available cores. On multi-core CPU systems (very likely nowadays), the parallel make will do the job much faster: $ make -j N On Linux/Mac, the following commands will configure a build with the default settings: $ tar xvfz These variables can be used to detect the Operating System.It is strongly advisable that the builds are done out-of-source, meaning that the build tree is located outside the source tree. Use the alternative method mentioned below instead.Īlternative method to detect to Operating System:ĬMake version 2.6 defines 2 different variables, which can be used to detect the Operating System preciously. Use the alternate method of detecting Operating System type, mentioned below instead.įor GNU/Linux: There is NO Variable for GNU/Linux. It only means that in the C/C++ header file _APPLE_ Macro is defined.

Note: Having this variable value set to TRUE does not necessarily mean that Operating System is Mac OS X. Is TRUE on all UNIX-like OS’s, including Apple OS X and CygWin These variables will be assigned with the values based on the platform, operating system etc.įor example, In CMake version 2.6 following Variables are present to identify the Operating System Type.

Finally I found the CMake syntax to write the platform specific code inside CMakeLists.txt.ĬMake actually defines several variables to identify the platform information. I was searching for this information from last three days.
