+# How to configure a parallel version of HDF5 on the Sandia National Laboratory
+# TFLOPS System that uses MPI and MPI-IO.
+
+# Read the INSTALL_TFLOPS 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.
+#
+
+# Using the MPICH libary by Daniel Sands.
+# It contains both MPI-1 and MPI-IO functions.

+# 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).
