/var/hpss/nfs/rmtab Lists all currently mounted HPSS directories.
/etc/hosts Contains an entry for each host on the network.
/etc/networks Contains information about subnetworks on the network.
7.5 MPI-IO API Configuration
MPI-IO is not enabled in the install image distribution as it must be configured specifically
for each site’s host MPI. The HPSS administrator must determine if MPI-IO support is
desired and, if so, which host MPI is to be used. A site-specific MPI-IO must be generated
usingmake in the src/mpi directory, after the appropriate configuration changes have been
made inMakefile.macros.
To enable MPI-IO, change theMPIO_SUPPORT in Makefile.macros toon. MPI-IO will be
configured to match theMPIO_MPI setting in the Makefile.macros, which selects the host MPI.
The HPSS administrator should choose the appropriate configuration to use when building the
MPI-IOsubsystem. To build the MPI-IO library, cd to the $HPSS_DIR/src/mpi and execute make.
This will generate an appropriate$HPSS_DIR/include/mpio_MPI_config.h.
Onlyone MPI host is supported for each HPSS system. To change the MPI host, the administrator
must edit the Makefile.macros to change the MPIO_MPI setting, and generate a newinclude/
mpio_MPI_config.h file by doing amake clean followed by a make in the src/mpi directory.
If the MPI host version is updated, HPSS MPI-IO should be reconfigured and remade, to be sure
any changes to the host interfaces are accurate. The administrator should follow the same
instructions as above for changing the MPI host.
We currently support MPI-IO API for the following host MPIs:
