Understanding HP-MPI
Running applications on Windows
Chapter 396
In order for remote processes to have access to network resources (such
as file shares), a domain password must be provided. This user password
will be used to create processes on the remote notes. The password is
SSPI encrypted before being sent across the network.
Passwords are provided using the -pass or -cache flags. The user will be
prompted for a password when the -pass or -cache flags are used.
Cached passwords are stored in an encrypted format.
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 only run if all libraries and executables
are located on local disks (including the user’s executable).
For experienced Linux or HP-UX HP-MPI users, mpirun appfile mode
options are the same on Windows 2003/XP, 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 36. For details on how
to run using -hostlist, see “Building and running on a Windows
2003/XP cluster using -hostlist” on page 110.
Submitting jobs
The section includes general information for submitting jobs either from
the GUI or the command line.
As part of the mpirun task submitted, the following flags are commonly
used with mpirun:
-ccp Automatically creates an appfile which matches the
CCP job allocation. The number of ranks run will equal
the number of processors requested.
-nodex When used in conjunction with the -ccp flag, will run
one rank per node in the CCP job allocation. (i.e.
number of ranks equals number of nodes, one rank per
node.)
-np N Indicates the number of ranks to execute.
-ccpblock Uses block scheduling to place ranks on allocated
nodes. Nodes will be processed in the order they were
allocated by the scheduler, with each node being fully
populated up to the total number of CPUs before
