- PRRTE has taken some steps towards Reproducible Builds (https://reproducible-builds.org/). Specifically, PRRTE’s `configure` and `make` process, by default, records the build date and some system-specific information such as the hostname where PRRTE was built and the username who built it. If you desire a Reproducible Build, set the `$SOURCE_DATE_EPOCH`, `$USER` and `$HOSTNAME` environment variables before invoking `configure` and `make`, and PRRTE will use those values instead of invoking `whoami` and/or `hostname`, respectively. See https://reproducible-builds.org/docs/source-date-epoch/ for information on the expected format and content of the `$SOURCE_DATE_EPOCH` variable.
