# if you want to compile with OpenMP, add this to the flags listed below, depending on the compiler you use:
#
# -fopenmp for GNU gfortran
# -openmp for Intel ifort
# -mp for Portland pgfortran
# -qsmp=omp for IBM xlf

# You can add -DFORCE_VECTORIZATION to the options below (for all compilers, except for IBM for which the syntax is -WF,-DFORCE_VECTORIZATION)
# to speed up the code in the fluid (acoustic) parts (only; FORCE_VECTORIZATION support for elastic parts has been discontinued in the source code).
# This works fine if (and only if) your computer always allocates a contiguous memory block for each allocatable array;
# this is the case for most machines and most compilers, but not all. For more details see https://github.com/geodynamics/specfem3d/issues/81 .
# To check if that option works fine on your machine, run the code with and without it for a model containing a significant fluid layer
# (or entirely fluid) and make sure the seismograms are identical.
# you can add -DUSE_SERIAL_CASCADE_FOR_IOs to the compiler options to make the mesher output mesh data
# to the disk for one MPI slice after the other, and to make the solver do the same thing when reading the files back from disk.
# First find the "real" compiler
# e.g., Cray provides a Programming Environment that wraps around compilers,
# but the command-line options are still compiler-specific.

# on some (but not all) IBM machines one might need to add -qsave otherwise the IBM compiler allocates the

#
# you will probably need to add " module load bgq-xl " or similar to your .bash_profile to load the compilers

# deleted -qxflag=dvz because it requires handler function __xl_dzx and thus linking will fail.

# it is small or negligible compared to other issues like slow I/O.
