Understanding HP-MPI
MPI options
Chapter 3 125
-ck Behaves like the -p option, but supports two additional
checks of your MPI application; it checks if the
specified host machines and programs are available,
and also checks for access or permission problems. This
option is only supported when using appfile mode.
-d Debug mode. Prints additional information about
application launch.
-j Prints the HP-MPI job ID.
-p Turns on pretend mode. That is, the system goes
through the motions of starting an HP-MPI application
but does not create processes. This is useful for
debugging and checking whether the appfile is set up
correctly. This option is for appfiles only.
-v Turns on verbose mode.
-i spec Enables runtime instrumentation profiling for all
processes. spec specifies options used when profiling.
The options are the same as those for the environment
variable MPI_INSTR. For example, the following is a
valid command line:
% $MPI_ROOT/bin/mpirun -i mytrace:l:nc \
-f appfile
Refer to “MPI_INSTR” on page 147 for an explanation
of -i options.
-T Prints user and system times for each MPI rank.
-tv Specifies that the application runs with the
TotalView debugger for LSF launched applications.
TV is only supported on XC systems.
RDMA control options
-dd Use deferred deregistration when registering and
deregistering memory for RDMA message transfers.
The default is to use deferred deregistration. Note that
using this option also produces a statistical summary
of the deferred deregistration activity when
MPI_Finalize is called. The option is ignored if the
