3. OpenMP Code Inspection#

Now we are going to explore and try to learn the OpenMP syntax indirectly. Look around online and find some basic OpenMP coding exampes. Once you found some examples, try them out on the HPCC. Answer the following questions when exploring and testing the examples you found.

  • What is the source where you found your examples?

  • What OpenMP specific commands do you see in the Code?

  • When comparing to other examples, which commands seem common and which commands rare?

  • What do the commands seem to do?

  • Did you encounter any challenges trying to get the examples up and running on the HPCC?
