hdf5/INSTALL_parallel.ascired
Albert Cheng 227aeb2c8b [svn-r441] MPIO library maintained by William M. Davidson (wmdavid) has been
changed to use system supported MPI library.  The path to it is
changed slightly too.  Updated all the paths variables.

# How to create a parallel version of HDF5 on the Intel Asci Red System
# that uses MPI and MPI-IO.
# Read the INSTALL.ascired file to understand the configure/make process
# for the sequential (i.e., uniprocessor) version of HDF5.
# The process for creating the parallel version of HDF5 using MPI-IO
# is similar, but first you will have to set up some environment variables
# with values specific to your local installation.
# The relevant variables are shown below, with values that work for Sandia'a
# ASCI Red Tflops machine as of the writing of these instructions (980421).
# Don't try to make a parallel version of HDF5 from the same hdf5 root
# directory where you made a sequential version of HDF5 -- start with
# a fresh copy.
# Here are the flags you must set before running the ./configure program
# to create the parallel version of HDF5.
# (We use sh here, but of course you can adapt to whatever shell you like.)
# compile for MPI jobs
CC=cicc
# The following flags are only needed when compiling/linking a user program
# for execution.

# Once these variables are set to the proper values for your installation,
# you can run the configure program (i.e., ./configure tflop --enable-parallel=mpio)
# to set up the Makefiles, etc.
# After configuring, run the make as described in the INSTALL file.
# When compiling and linking your application, don't forget to compile with
# cicc and link to the MPI-IO library and the parallel version of the HDF5
# library (that was created and installed with the configure/make process).
