mpi is not recognized when I compile the Fortran code.

[FeiYa]

I've installed the Fortran compiler and mpi lib. When I use commands 'which ifort' and 'which mpirun' to check, it shows the correct direction where I installed it. 

However, the 'mpi' still can not be recognized when I compile the code.

Can you tell me how to solve this problem?

If you need additional advice on using Intel MPI, you can ask MPI questions on the oneAPI HPC Toolkit forum.
