# 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
|
|

|
# 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,

|
# After configuring, run the make as described in the INSTALL file.
|

# When compiling and linking your application, don't forget to compile with

|
|
# library (that was created and installed with the configure/make process).
