Understanding HP-MPI
MPI options
Chapter 3 127
Environment control options
-e var[=val] Sets the environment variable var for the program and
gives it the value val if provided. Environment
variable substitutions (for example, $FOO) are
supported in the val argument. In order to append
additional settings to an existing variable, %VAR can
be used as in the example in “Setting remote
environment variables” on page 79.
-sp paths Sets the target shell PATH environment variable to
paths. Search paths are separated by a colon.
Special HP-MPI mode option
-ha Eliminates a teardown when ranks exit abnormally.
Further communications involved with ranks that are
unreachable return error class MPI_ERR_EXITED, but do
not force the application to teardown, as long as the
MPI_Errhandler is set to MPI_ERRORS_RETURN. Some
restrictions apply:
• Communication is done via TCP/IP (Does not use
shared memory for intranode communication.)
• Cannot be used with the diagnostic library.
• Cannot be used with -i option
Windows CCP
The following are specific mpirun command line options for Windows
CCP users.
-ccp Indicates that the job is being submitted through the
Windows CCP job scheduler/launcher. This is the
recommended method for launching jobs. Required for
all CCP jobs.
-ccperr <filename>
Assigns the job’s standard error file to the given
filename when starting a job through the Windows
CCP automatic job scheduler/launcher feature of
HP-MPI. This flag has no effect if used for an existing
CCP job.
