HP-MPI Version 1.1 for Windows Release Note

HP-MPI V1.1 for Windows Release Note

Running HP-MPI on Windows 2003/XP

To run HP-MPI on Windows 2003/XP systems use appfile mode or the -hostlist/-hostfile

flags.

For remote processes to have access to network resources (such as file shares), a password

which is used to create processes on the remote nodes must be provided. The password is SSPI

encrypted before being sent across the network.

Passwords are provided using the -pass or -cache flags.

Authentication does not require a password, but remote access to network resources does.

Because of this, using a -nopass option will create remote processes that will run if all

libraries and executables are located on local disks (including the user’s ranks.exe).

For experienced Linux or HP-UX HP-MPI users, mpirun with appfile options are the same for

Windows 2003/XP as other platforms, with the exception of the -package, -token, -pass,

-cache, -nopass, -iscached, and -clearcache options.

For details on how to run in appfile mode, see “Building and running on a Windows 2003/XP

cluster using appfiles” on page 38. For details on how to run using -hostlist, see “Building

and running on a Windows 2003/XP cluster using -hostlist” on page 40.
