Understanding HP-MPI
MPI options
Chapter 3 129
-headnode <headnode> This option is used on Windows CCP to indicate
the headnode to submit the mpirun job. If omitted,
localhost is used. This option can only be used as a
command line option when using the mpirun automatic
submittal functionality.
-hosts This option used on Windows CCP allows you to specify
a node list to HP-MPI. Ranks are scheduled according
to the host list. The nodes in the list must be in the job
allocation or a scheduler error will occur. The HP-MPI
program %MPI_ROOT%\bin\mpi_nodes.exe returns a
string in the proper -hosts format with scheduled job
resources.
-jobid <job-id>
This flag used on Windows CCP will schedule an
HP-MPI job as a task to an existing job. It will submit
the command as a single CPU mpirun task to the
existing job indicated by the parameter job-id. This
option can only be used as a command line option when
using the mpirun automatic submittal functionality.
-nodex Used on Windows CCP in addition to -ccp to indicate
that only one rank is to be used per node, regardless of
the number of CPU’s allocated with each host.
Windows 2003/XP
The following are specific mpirun command line options for Windows
2003/XP users.
-package <package-name>
-pk <package-name>
When HP-MPI authenticates with the HP-MPI Remote
Launch service, it will authenticate using an installed
Windows security package (e.g. Kerberos, NTLM,
Negotiate, etc.). By default, HP-MPI will negotiate the
package to use with the service, and no interaction or
package specification is required by the user. 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) will negotiate the security package to
be used for authentication.
