MPI options
Chapter 3130
-token <token-name>
-tg <token-name>
Authenticates to this token with the HP-MPI Remote
Launch service. Some authentication packages require
a token name. The default is no token.
-pass Prompts the user for his domain account password.
Used to authenticate and create remote processes. A
password is required to allow the remote process to
access network resources (such as file shares). The
password provided is encrypted using SSPI for
authentication. The password is not cached when using
this option.
-cache Prompts the user for his domain account password.
Used to authenticate and create remote processes. A
password is required to allow the remote process to
access network resources (such as file shares). The
password provided is encrypted using SSPI for
authentication. The password will be cached so that
future mpirun commands will use the cached password.
Passwords are cached in encrypted form, using
Windows Encryption APIs.
-nopass Executes the mpirun command with no password. If a
password is cached, it is not accessed and no password
is used to create the remote processes. Using no
password will result in the remote processes not having
access to network resources. This option will also
suppress the 'no password cached' warning. This is
useful when no password is desired for SMP jobs.
-iscached Indicates if a password is stored in the user password
cache and stops execution. The MPI application will
not launch if this option is included on the command
line.
-clearcache Clears the password cache and stops. The MPI
application will not launch if this option is included on
the command line.
