HP-MPI Version 1.2 for Windows Release Note

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. 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.
1.2.4.4 Debugging Applications
HP-MPI V1.2 provides a browser-based tutorial on how to debug applications that use HP-MPI
in the Windows environment. The tutorial provides step-by-step procedures for performing
common debugging tasks using Visual Studio 2005. These procedures have not been updated
for Visual Studio 2008.
1.2.4.5 Support for 32-bit IBAL
The current version of the WinOF 2.0 drivers do not include 32-bit support. Therefore, HP-MPI
V1.2 does not currently support 32-bit IBAL for Windows 2008/HPCS.
1.2.4.6 mpidiag Tool for Windows 2008 and HP-MPI Remote Launch Service
HP-MPI for Windows 2008 includes the mpidiag diagnostic tool. It is located in %MPI_ROOT%\
bin\mpidaig.exe.
This tool is useful to diagnose remote service access without running mpirun. To use the tool,
run mpidiag with -s <remote-node> <options>, where options include:
-help Show the options to mpidiag.
-s <remote-node>
Connect to and diagnose the remote service of this node.
-at
Authenticates with the remote service and returns the remote
authenticated user’s name.
-st
Authenticates with remote service and returns service status.
-et <echo-string>
Authenticates with the remote service and performs a simple echo
test, returning the string.
-sys
Authenticates with the remote service and returns remote system
information, including node name, CPU count, and username.
-ps [username]
Authenticates with the remote service and lists processes running on
the remote system. If a username is included, only that user’s
processes are listed.
-dir <path>
Authenticates with the remote service and lists the files for the given
path. This is a useful tool to determine if access to network shares
are available to the authenticated user.
-sdir <path> Same as -dir, but lists a single file. No directory contents are listed.
Only the directory is listed if accessible.
