Compiler Library requirements

The CMake build system is used to manage the large number of dependencies and external libraries needed to compile GEMINI.
If needed, CMake is easily installed in a minute without sudo/admin on:

• Linux: use cmake_setup.py
• MacOS: brew install cmake
• Windows

Compilers

Compiler wrappers mpifort or mpiifort can be used. Fortran 2008 submodule and other Fortran 2008 throughout GEMINI requires a Fortran 2008 compliant compiler. Such compilers include:

• gfortran ≥ 6
• Intel ifort ≥ 16
• Cray ftn
• IBM XL

It is anticipated in 2020 some of the following compilers will also be working:

• Flang
• NAG
• PGI

Libraries

Tested versions include:

• HDF5 1.8, 1.10, 1.12
• OpenMPI 1.10, 2.1, 3.1, 4.0
• MUMPS 4.10, 5.1, 5.2
• SCALAPACK 2.0, 2.1
• LAPACK95 3.0 (optional)
• NCAR GLOW (optional) enabled by cmake -Dglow=yes option
