Running as root is *strongly* discouraged as any mistake (e.g., in
|
|
defining TMPDIR) or bug can result in catastrophic damage to the OS
|
|
file system, leaving your system in an unusable state.
|
|
|
|
We strongly suggest that you run mpirun as a non-root user.
|
|
|
|
You can override this protection by adding the --allow-run-as-root option
|
|
to the cmd line or by setting two environment variables in the following way:
|
|
the variable OMPI_ALLOW_RUN_AS_ROOT=1 to indicate the desire to override this
|
|
protection, and OMPI_ALLOW_RUN_AS_ROOT_CONFIRM=1 to confirm the choice and
|
|
add one more layer of certainty that you want to do so.
|
|
We reiterate our advice against doing so - please proceed at your own risk.
