Program examples

If you have not done so already copy our examples to your home directory by running the following command:

 cp -r /apps/gent/tutorials/Intro-HPC/examples ~/

_{~(tilde) refers to your home directory, the directory you arrive by default when you login.}

Go to our examples:

cd ~/examples/Program-examples

Here, we just have put together a number of examples for your convenience. We did an effort to put comments inside the source files, so the source code files are (should be) self-explanatory.

1. 01_Python

2. 02_C_C++

3. 03_Matlab

4. 04_MPI_C

5. 05a_OMP_C

6. 05b_OMP_FORTRAN

7. 06_NWChem

8. 07_Wien2k

9. 08_Gaussian

10. 09_Fortran

11. 10_PQS

The above 2 OMP directories contain the following examples:

C Files	Fortran Files	Description
omp_hello.c	omp_hello.f	Hello world
omp_workshare1.c	omp_workshare1.f	Loop work-sharing
omp_workshare2.c	omp_workshare2.f	Sections work-sharing
omp_reduction.c	omp_reduction.f	Combined parallel loop reduction
omp_orphan.c	omp_orphan.f	Orphaned parallel loop reduction
omp_mm.c	omp_mm.f	Matrix multiply
omp_getEnvInfo.c	omp_getEnvInfo.f	Get and print environment information
omp_bug1.c omp_bug1fix.c omp_bug2.c omp_bug3.c omp_bug4.c omp_bug4fix omp_bug5.c omp_bug5fix.c omp_bug6.c	omp_bug1.f omp_bug1fix.f omp_bug2.f omp_bug3.f omp_bug4.f omp_bug4fix omp_bug5.f omp_bug5fix.f omp_bug6.f	Programs with bugs and their solution

Compile by any of the following commands:

C:	icc -openmp omp_hello.c -o hello\newline pgcc -mp omp_hello.c -o hello\newline gcc -fopenmp omp_hello.c -o hello
Fortran:	ifort -openmp omp_hello.f -o hello\newline pgf90 -mp omp_hello.f -o hello\newline gfortran -fopenmp omp_hello.f -o hello

Be invited to explore the examples.
