+ | First, make sure that mpic++ and nvcc are available by | ||
+ | <code bash> | ||
+ | $ which mpic++ | ||
+ | $ which nvcc | ||
+ | </code> | ||
+ | You should be expecting output that looks like | ||
+ | <code bash> | ||
+ | $ which mpic++ | ||
+ | /usr/lib64/mpich/bin/mpic++ | ||
+ | $ which nvcc | ||
+ | /usr/local/cuda/bin/nvcc | ||
+ | </code> | ||
+ | If you are sure that MPI and CUDA are present, but still get messages like | ||
+ | <code bash> | ||
+ | /usr/bin/which: no mpic++ in (/usr/local/bin:/bin:/usr/bin) | ||
+ | </code> | ||
+ | Then adjust **''Makefile.meso''** located in **''USER-MESO/MAKE''** by setting the **''CC''** and **''MPICXX''** environment variables to be the absolute path to nvcc and mpic++, respectively. | ||
