# opalCC(1)

Part of [opal\_wrapper(1)](/opal_wrapper/1.md).

opal\_wrapper — Back-end Open MPI wrapper command

## DESCRIPTION

**opal\_wrapper** is not meant to be called directly by end users. It is automatically invoked as the back-end by the Open MPI wrapper commands such as: **mpicc**, **mpicxx**, and **mpifort** (and its legacy/deprecated aliases **mpif77** and **mpif90**).

Some Open MPI installations may have additional wrapper commands, and/or have renamed the wrapper compilers listed above to avoid executable name conflicts with other MPI implementations. Hence, you may also have wrapper compilers installed including the following names: **mpifort.openmpi** (and the legacy/deprecated aliases **mpif90.openmpi** and **mpif77.openmpi**), **mpicxx.openmpi**, **mpicc.openmpi**.

**SEE ALSO:**

The following may exist depending on your particular Open MPI installation: *[mpicc(1)](/mpicc/1.md)*, *[mpicxx(1)](/mpicxx/1.md)*, *[mpifort(1)](/mpifort/1.md)*
