HP-MPI Version 2.0 for Windows Release Note

NOTE: The mpirun -pwcheck option, along with other
HP-MPI password options, run with HP-MPI Remote
Launch Service, and do not refer to Windows HPC user
passwords. When running through Windows HPC
scheduler (with -hpc), you might need to cache a password
through the Windows HPC scheduler. For more
information, see the Windows HPC job command.
-package <package-name> and
-pk <package-name>
When HP-MPI authenticates with the HP-MPI Remote
Launch service, it authenticates using an installed Windows
security package (for example Kerberos, NTLM, Negotiate,
and more). By default, HP-MPI negotiates the package to
use with the service, and no interaction or package
specification is required. If a specific installed Windows
security package is preferred, use this flag to indicate that
security package on the client. This flag is rarely necessary
as the client (mpirun) and the server (HP-MPI Remote
Launch service) negotiates the security package to be used
for authentication.
-token <token-name> and -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 for a 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 for a 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
cached so that future mpirun commands uses 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
results in the remote processes not having access to
network resources. Use this option if you are running
locally. This option also suppresses 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 does not launch
if this option is included on the command line.
-clearcache
Clears the password cache and stops. The MPI application
does not launch if this option is included on the command
line.
