PMIx Reference Runtime Environment (PRRTE) v3.0.12 — PMIx Reference Run Time Environment 3.0.12 documentation

# PMIx Reference Runtime Environment (PRRTE) v3.0.12

The project is formally referred to in documentation by “PRRTE”, and the GitHub repository is `prrte`.

Note

We have found that most users do not like typing the two consecutive `r` letters in the name. Hence, all of the internal API symbols, environment variables, MCA frameworks, and CLI executables all use the abbreviated `prte` (one `r`, not two) for convenience.
