The Weather Research and Forecasting (WRF) Model is a next-generation mesoscale numerical weather prediction system designed to serve both operational forecasting and atmospheric research needs. It features multiple dynamical cores, a 3-dimensional variational (3DVAR) data assimilation system, and a software architecture allowing for computational parallelism and system extensibility. WRF is suitable for a broad spectrum of applications across scales ranging from meters to thousands of kilometers.
This description was taken from The Weather Research&Forecasting Model Website.

There are four main WRF building modes:
  • for serial execution (serial);
  • for parallel execution on symmetric multiprocessing (SMP) systems with OpenMP environment (smpar);
  • for distributed execution with MPI environment (dmpar);
  • for hybrid execution with MPI and OpenMP environment (dm+sm).
Building of the WRF for Linux* is officially supported by this compilers list:

To help with WRF building on Linux* with Intel Compilers and improving performance on Intel® Architecture Intel provides 4 knowledge base articles:

Although each article refers to a specific version of WRF, any version may be built in any of the above modes using the Intel compiler.

Intel provides the following knowledge base article for building on Linux* the WRF Preprocessing System (WPS) with Intel compilers:
Building the WPS with Intel® Fortran Compilers on Linux* for serial mode execution.
