FORTRAN modules for HEP

description

Fortran modules for High Energy Physics
Some fun and useful modules I have written that are commonly used in HEP.
The modules are separated in folders, written using Fortran 90 standard, most of them with corresponding main program.

installation

If you haven't already got Fortran setup on your PC, please read through the setup guide in the documentation.
If you have fortran compiler setup, just create a folder and copy the module file <module_name>.f90 and main program main.f90 into it to start playing.

usage

copy the module file <module_name>.f90 into the same directory as your main program main.f90.
It can then be compiled with the following code (assuming gfortran is your favourite compiler):

gfortran -c <module_name>.f90 main.f90

gfortran -o <my_program> *.o

note that some modules might need extra compiler flags in order for it to work.

dependencies

note that module dependencies affect the order of compilation.
One can keep track of dependency with a makefile using make.
Or handle dependency using makedepf90 for linux based OS.
Or simply use cmake.
The following Link provides some info on build tools.

modules

Listed below are some common modules that are useful in high energy physics calculations:

  • color

    a simple module that allow colored output to the terminal

  • gauss

    a standalone Gauss-Legendre quadrature subroutine with 4, 8, 16, 32, and 64 points.

  • glauber_mc

    Monte Carlo Glauber subroutine

  • glauber_opt

    optical Glauber subroutine

  • time

    a module with subroutines that can keep track of program start/stop time and run durations

  • vec_2D

    a 2D vector class with vector opeartion methods

  • vegas_nr

    VEGAS multi-dimensional Monte Carlo integration subroutine developed by "Numerical Recipe"

  • vint

    a mininum VEGAS module based on vegas-nr that is self-contained in a single module file

  • vish_gen

    generates a 3d table of parton quenching paths using Viscous Israel-Stewart Hydrodynamics

  • vish_read

    reads the 3d table generated by vish_gen and provides an interpolated value
