Setting Up Programming Environment¶

1. Load the compiler module¶

We will work with the GNU compiler for compiling and testing OpenMP code.

$ source module.sh

Check if the module is loaded properly

$ module list

Currently Loaded Modules:
  1) GCCcore/11.3.0
  2) Arm-Forge/22.0.4-GCC-11.3.0
  3) AMD-uProf/3.6.449
  4) Advisor/2022.1.0
  5) VTune/2022.3.0
  ...

2. Compile your OpenMP application¶

Compilation

C/C++

$ g++ <source_file>.cc -fopenmp -o <output>

FORTRAN

$ gfortran <source_file>.f90 -fopenmp -o <output>

For example:

Example compilation

C/C++

$ g++ Hello-world.cc -fopenmp -o Hello-World

FORTRAN

$ gfortran Hello-world.f90 -fopenmp -o Hello-World

3. Execute your application¶

$ ./<output>

For example:

$ ./Hello-World

Hello world from the master thread
Hello world from thread id 0 from the team size of 5
Hello world from thread id 3 from the team size of 5
Hello world from thread id 1 from the team size of 5
Hello world from thread id 4 from the team size of 5
Hello world from thread id 2 from the team size of 5
