Change in Documentation for the INSTALL process on the ASCI Red
Problem:
As part of the parallel HDF5 install process, upon compiling the
library and sequential testers, it is necessary to copy the testers
onto local disk prior to testing. This is almost done by steps 9-11)
...
9) cp -r ../hdf5 ../scratch
10) cd /scratch/hdf5/test
11) make test >&! test.out
After the copying to /scratch, when the "make test" is run,
dependencies are checked and it is determined that the executables
need to be rebuilt. Unfortunately, the MPI-IO libraries in
sasn100:/usr/community/mpi-io are not accessible on ASCI Red, so
that step #11 above gives an error.
Solution:
Albert Cheng and Robb Matzke suggested to add the "-p" option in
step #9, if available, to maintain the original modifications.
Those install steps were changed to:
...
9) cp -rp ../hdf5 ../scratch
10) cd /scratch/hdf5/test
11) make test >&! test.out
Everything works fine!

FOR THE INTEL TFLOPS MACHINE:
|
|
|
|
Below are the step-by-step procedures for building, testing, and
|
|
installing both the sequential and parallel versions of the HDF5 library.
|
|
|
|
---------------
|
|
Sequential HDF5:
|
|
---------------
|
|
|
|
The setup process for building the sequential HDF5 library for the
|
|
ASCI Red machine is done by a coordination of events from sasn100 and
|
|
janus. Special effort must be made to move the compiled and linked
|
|
testers to disks local to the processors for execution. This special
|
|
effort is shown here at steps 9) and steps 10).
|
|
|
|
The total required steps are something similar to:
|
|
FROM SASN100,
|
|
|
|
1) uncompress hdf5-1.0.0a.tar.Z
|
|
|
|
2) tar xvf hdf5-1.0.0a.tar
|
|
|
|
3) cd ./hdf5
|
|
|
|
4) ./configure tflop
|
|
|
|
5) make H5detect
|
|
|
|
|
|
FROM JANUS,
|
|
|
|
6) cd ./hdf5
|
|
|
|
7) make H5Tinit.c
|
|
|
|
|
|
FROM SASN100,
|
|
|
|
8) make >&! comp.out &
|
|
|
|
|
|
When everything is finished compiling and linking,
|
|
FROM JANUS,
|
|
|
|
9) cp -r ../hdf5 /scratch
|
|
|
|
10) cd /scratch/hdf5/test
|
|
|
|
11) make test >&! test.out
|
|
|
|
|
|
Once satisfied with the test results, as long as you
|
|
have the correct permission,
|
|
FROM SASN100,
|
|
|
|
12) make install
|
|
|
|
|
|
---------------
|
|
Parallel HDF5:
|
|
---------------
|
|
|
|
The setup process for building the parallel version of the HDF5 library for the
|
|
ASCI Red machine is very similar to the sequential version. It is done by a
|
|
coordination of events from sasn100 and janus. Special effort must be made to
|
|
move the compiled and linked single processor testers to disks local to the
|
|
processor for execution. This special effort is shown here at steps 9) and
|
|
steps 10). Following these test, there are the edit, compile, link, and
|
|
execution of parallel tests described in steps 12) through 16).
|
|
|
|
|
|
The total required steps are something similar to:
|
|
FROM SASN100,
|
|
|
|
1) uncompress hdf5-1.0.0a.tar.Z
|
|
|
|
2) tar xvf hdf5-1.0.0a.tar
|
|
|
|
3) cd ./hdf5
|
|
|
|
4) sh INSTALL_parallel.ascired /* this is different from the sequential version */
|
|
|
|
5) make H5detect
|
|
|
|
|
|
FROM JANUS,
|
|
|
|
6) cd ./hdf5
|
|
|
|
7) make H5Tinit.c
|
|
|
|
|
|
FROM SASN100,
|
|
|
|
8) make >&! comp.out &
|
|
|
|
|
|
When everything is finished compiling and linking,
|
|
FROM JANUS,
|
|
|
|
9) cp -rp ../hdf5 /scratch
|
|
|
|
10) cd /scratch/hdf5/test
|
|
|
|
11) make test >&! test.out
|
|
|
|
|
|
Once satisfied with the single processor test results,
|
|
FROM SASN100,
|
|
|
|
12) cd testpar
|
|
|
|
13) /* edit testphdf5.c, edit the following line */
|
|
char *filenames[]={ "pfs:/pfs/multi/tmp_1/your_own/Eg1.h5f", "pfs:/pfs/multi/tmp_1/your_own/Eg2.h5f" };
|
|
|
|
/* change "your_own" to your own directory name */
|
|
char *filenames[]={ "pfs:/pfs/multi/tmp_1/my_name/Eg1.h5f", "pfs:/pfs/multi/tmp_1/my_name/Eg2.h5f" };
|
|
|
|
/* delete or comment-out the next line */
|
|
char *filenames[]={ "ParaEg1.h5f", "ParaEg2.h5f" };
|
|
|
|
14) make -f Makefile.ascired
|
|
|
|
When everything is finished compiling and linking,
|
|
FROM JANUS,
|
|
|
|
15) cd ./hdf5/testpar
|
|
|
|
16) make test -f Makefile.ascired >&! test.out
|
|
|
|
|
|
Once satisfied with the parallel test results, as long as you
|
|
have the correct permission,
|
|
FROM SASN100,
|
|
|
|
17) make install
|
