PFMICE

PFMICE

Description

This is a 3D test case of the code PFMICE

Getting Started

Dependencies

• PFMICE is written with Fortran. Before you try to install PFMICE on your local computer or workstation, Fortran compiler (GCC or Intel Fortran) and MPI libraries (e.g., openmpi or Intel MPI) must be installed. OpenMPI is freely available online:

https://www.open-mpi.org/software/ompi/v4.1/.

and it can be installed in the following steps:

gunzip -c openmpi-4.1.1.tar.gz | tar xf -

cd openmpi-4.1.1

./configure --prefix=/usr/local

<...lots of output...>

make all install

Intel oneAPI Toolkits can be found in:

https://software.intel.com/content/www/us/en/develop/tools/oneapi/all-toolkits.html

Installing

• A Makefile can be found in the folder. If your current compiling environment is GCC+OpenMPI, in the Makefile, you should use:

FC = mpif90

FFLAGS := -O3 -ffixed-line-length-none -mcmodel=large -fdefault-real-8 -cpp -Wall -fcheck=all

For Intel compiler+Intel MPI, the setup in the Makefile will be:

FC = mpiifort

FFLAGS := -r8 -fpconstant -O3 -132 -cpp

To compile the code, you need to compile the libraries at first with:

make libraries

and then compile the source code with:

make

you can remove the executables with:

make clean

• Any modifications needed to be made to files/folders

Executing program

• To run the code:

mpirun -np N PFMICE

where N is the number of CPU cores.
