Environment[edit]
The discussion of OMP_SCHEDULE is adrift without prior discussions of loop scheduling and processor affinity, so we should write text for those topics or else remove this discussion. OMP_DYNAMIC and OMP_NESTED are not explained and there are other env vars that matter (https://computing.llnl.gov/tutorials/openMP/#EnvironmentVariables) so I'm not sure why exactly those four are mentioned.

References[edit]

Directives[edit]
The table of directives and clauses is ill-explained, adrift, and unfriendly, AND contains errors in the wiki markup (e.g. the DEFAULT clause isn't rendered properly). The same content is available and better contextualized in the external tutorials or the OpenMP.org reference cards, so we should probably remove the table.
