Removes H5detect and H5make_libsettings from the build and replaces their functionality with things that don't affect cross-compiling. H5detect --> floating-point types are now detected on library load H5make_libsettings --> Moved functionality to a new H5build_settings.c template file

|
|
I. Prerequisites
|
|
========================================================================
|
|
1. Create a working directory that is accessible from the compute nodes for
|
|
running tests; the working directory should be in a scratch space or a
|
|
parallel file system space since testing will use this space. Building
|
|
from HDF5 source in a 'home' directory typically results in test
|
|
failures and should be avoided.
|
|
|
|
2. Load modules for desired compilers, module for cmake version 3.18 or greater,
|
|
and set any needed environment variables for compilers (i.e., CC, FC, CXX).
|
|
Unload any problematic modules (i.e., craype-hugepages2M).
|
|
|
|
========================================================================
|
|
II. Obtain HDF5 source
|
|
========================================================================
|
|
Obtain HDF5 source code from the HDF5 repository using a git command or
|
|
from a release tar file in a working directory:
|
|
|
|
git clone https://github.com/HDFGroup/hdf5.git
|
|
[-b branch] [source directory]
|
|
|
|
If no branch is specified, then the 'develop' version will be checked out.
|
|
If no source directory is specified, then the source will be located in the
|
|
'hdf5' directory. The CMake scripts expect the source to be in a directory
|
|
named hdf5-<version string>, where 'version string' uses the format '1.xx.xx'.
|
|
|
|
If the version number is not known a priori, the version string
|
|
can be obtained by running bin/h5vers in the top level directory of the source clone, and
|
|
the source directory renamed 'hdf5-<version string>'.
|
|
|
|
Release or snapshot tar files may also be extracted and used.
|
|
|
|
========================================================================
|
|
III. Using ctest command to build and test
|
|
========================================================================
|
|
|
|
The ctest command [1]:
|
|
|
|
ctest -S HDF5config.cmake,BUILD_GENERATOR=Unix -C Release -V -O hdf5.log
|
|
|
|
will configure, build, test and package HDF5 from the downloaded source
|
|
after the setup steps outlined below are followed.
|
|
|
|
CMake option variables are available to allow running test programs in batch
|
|
scripts on compute nodes and to cross-compile for compute node hardware using
|
|
a cross-compiling emulator. The setup steps will make default settings for
|
|
parallel or serial only builds available to the CMake command.
|
|
|
|
1. The "hdf5" directory should be renamed hdf5-<version string>. For
|
|
further explanation see section II.
|
|
|
|
2. Three cmake script files need to be copied to the working directory, or
|
|
have symbolic links to them, created in the working directory:
|
|
|
|
hdf5-<version string>/config/cmake/scripts/HDF5config.cmake
|
|
hdf5-<version string>/config/cmake/scripts/CTestScript.cmake
|
|
hdf5-<version string>/config/cmake/scripts/HDF5options.cmake
|
|
|
|
should be copied to the working directory.
|
|
|
|
3. The resulting contents of the working directory are then:
|
|
|
|
CTestScript.cmake
|
|
HDF5config.cmake
|
|
HDF5options.cmake
|
|
hdf5-<version string>
|
|
|
|
Additionally, when the ctest command runs [1], it will add a build directory
|
|
in the working directory.
|
|
|
|
4. The following options (among others) can be added to the ctest
|
|
command [1], following '-S HDF5config.cmake,' and separated by ',':
|
|
|
|
HPC=sbatch (or 'bsub' or 'raybsub') indicates which type of batch
|
|
files to use for running tests. If omitted, test
|
|
will run on the local machine or login node.
|
|
|
|
KNL=true to cross-compile for KNL compute nodes on CrayXC40
|
|
(see section IV)
|
|
|
|
MPI=true enables parallel, disables c++, java, and threadsafe
|
|
|
|
LOCAL_BATCH_SCRIPT_ARGS="--account=<account#>" to supply user account
|
|
information for batch jobs
|
|
|
|
The HPC options will add BUILD_GENERATOR=Unix for the three HPC options.
|
|
An example ctest command for a parallel build on a system using sbatch is
|
|
|
|
ctest -S HDF5config.cmake,HPC=sbatch,MPI=true -C Release -V -O hdf5.log
|
|
|
|
Adding the option 'KNL=true' to the above list will compile for KNL nodes,
|
|
for example, on 'mutrino' and other CrayXC40 machines.
|
|
|
|
Changing -V to -VV will produce more logging information in HDF5.log.
|
|
|
|
More detailed CMake information can be found in the HDF5 source in
|
|
release_docs/INSTALL_CMake.txt.
|
|
|
|
========================================================================
|
|
IV. Cross-compiling
|
|
========================================================================
|
|
For cross-compiling on Cray, set environment variables CC=cc, FC=ftn
|
|
and CXX=CC (for c++) after all compiler modules are loaded since switching
|
|
compiler modules may unset or reset these variables.
|
|
|
|
CMake provides options for cross-compiling. To cross-compile for KNL hardware
|
|
on mutrino and other CrayXC40 machines, add HPC=sbatch,KNL=true to the
|
|
ctest command line. This will set the following options from the
|
|
config/cmake/scripts/HPC/sbatch-HDF5options.cmake file:
|
|
|
|
set (COMPILENODE_HWCOMPILE_MODULE "craype-haswell")
|
|
set (COMPUTENODE_HWCOMPILE_MODULE "craype-mic-knl")
|
|
set (LOCAL_BATCH_SCRIPT_NAME "knl_ctestS.sl")
|
|
set (LOCAL_BATCH_SCRIPT_PARALLEL_NAME "knl_ctestP.sl")
|
|
set (ADD_BUILD_OPTIONS "${ADD_BUILD_OPTIONS} -DCMAKE_TOOLCHAIN_FILE:STRING=config/toolchain/crayle.cmake")
|
|
|
|
On the Cray XC40 the craype-haswell module is needed for configuring, and the
|
|
craype-mic-knl module is needed for building to run on the KNL nodes. CMake
|
|
with the above options will swap modules after configuring is complete,
|
|
but before compiling programs for KNL.
|
|
|
|
The sbatch script arguments for running jobs on KNL nodes may differ on CrayXC40
|
|
machines other than mutrino. The batch scripts knl_ctestS.sl and knl_ctestP.sl
|
|
have the correct arguments for mutrino: "#SBATCH -p knl -C quad,cache". For
|
|
cori, another CrayXC40, that line is replaced by "#SBATCH -C knl,quad,cache".
|
|
For cori (and other machines), the values in LOCAL_BATCH_SCRIPT_NAME and
|
|
LOCAL_BATCH_SCRIPT_PARALLEL_NAME in the config/cmake/scripts/HPC/sbatch-HDF5options.cmake
|
|
file can be replaced by cori_knl_ctestS.sl and cori_knl_ctestS.sl, or the lines
|
|
can be edited in the batch files in hdf5-<version string>/bin/batch (see section II
|
|
for version string explanation).
|
|
|
|
========================================================================
|
|
V. Manual alternatives
|
|
========================================================================
|
|
If using ctest is undesirable, one can create a build directory and run the cmake
|
|
configure command, for example
|
|
|
|
"/projects/Mutrino/hpcsoft/cle6.0/common/cmake/<CMake version>/bin/cmake"
|
|
-C "<working directory>/hdf5-<version string>/config/cmake/cacheinit.cmake"
|
|
-DCMAKE_BUILD_TYPE:STRING=Release -DHDF5_BUILD_FORTRAN:BOOL=ON
|
|
-DHDF5_BUILD_JAVA:BOOL=OFF
|
|
-DCMAKE_INSTALL_PREFIX:PATH=<working directory>/HDF_Group/HDF5/<version string>
|
|
-DHDF5_ENABLE_Z_LIB_SUPPORT:BOOL=OFF -DHDF5_ENABLE_SZIP_SUPPORT:BOOL=OFF
|
|
-DHDF5_ENABLE_PARALLEL:BOOL=ON -DHDF5_BUILD_CPP_LIB:BOOL=OFF
|
|
-DHDF5_BUILD_JAVA:BOOL=OFF -DHDF5_ENABLE_THREADSAFE:BOOL=OFF
|
|
-DHDF5_PACKAGE_EXTLIBS:BOOL=ON -DLOCAL_BATCH_TEST:BOOL=ON
|
|
-DMPIEXEC_EXECUTABLE:STRING=srun -DMPIEXEC_NUMPROC_FLAG:STRING=-n
|
|
-DMPIEXEC_MAX_NUMPROCS:STRING=6
|
|
-DCMAKE_TOOLCHAIN_FILE:STRING=config/toolchain/crayle.cmake
|
|
-DLOCAL_BATCH_SCRIPT_NAME:STRING=knl_ctestS.sl
|
|
-DLOCAL_BATCH_SCRIPT_PARALLEL_NAME:STRING=knl_ctestP.sl -DSITE:STRING=mutrino
|
|
-DBUILDNAME:STRING=par-knl_GCC493-SHARED-Linux-4.4.156-94.61.1.16335.0.PTF.1107299-default-x86_64
|
|
"-GUnix Makefiles" "" "<working directory>/hdf5-<version string>"
|
|
|
|
followed by make and batch jobs to run tests.
|
|
|
|
To cross-compile on CrayXC40, run the configure command with the craype-haswell
|
|
module loaded, then switch to the craype-mic-knl module for the build process.
|
|
|
|
Tests on machines using slurm can be run with
|
|
|
|
"sbatch -p knl -C quad,cache ctestS.sl"
|
|
|
|
or
|
|
|
|
"sbatch -p knl -C quad,cache ctestP.sl"
|
|
|
|
for parallel builds.
|
|
|
|
Tests on machines using LSF will typically use "bsub ctestS.lsf", etc.
