#    Run hybrid WARP3D on Linux (MPI + OpenMP) 
#    Built with Intel Fortran + MPI system
#    =========================================
#
#    Last updated: March 7, 2019  (RHD)
#
#    This bash script runs the "hybrid" version of WARP3D that
#    includes MPI, OpenMP. The Intel MKL libraries
#    are used by hypre, Pardiso, and Cluster Pardiso solvers.

echo "        - model must have domain decomposition w/ domains assigned in blocking"

echo "      Guidelines:"
echo "      -----------"
echo "  "
echo "       1. number of MPI ranks (NP) must = number of domains defined in model input"
echo "          We recommend using NP = number of physical processors available"
