HP-MPI Version 2.0 for Windows Release Note

7 Running HP-MPI on Windows

To run HP-MPI on Windows XP/Vista/2003/2008 (non-HPCS) systems, use the 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.

To check for valid cached passwords, use the -pwcheck option.

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

of this, using a -nopass option creates remote processes that 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 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 2008 Cluster

Using Appfiles” (page 42). For details on how to run using -hostlist, see “Building and

Running on a Windows 2008 Cluster Using -hostlist” (page 43).
