Subject: [Hdf-forum] Building HDF5 with parallel support
Hi,
I'm trying to build hdf5-1.10.0-patch1. I'm trying to build it with a
variety of compilers: GCC 5.4.0, GCC 6.1.0, Intel 2015 and PGI 16.5 (we
support a lot of compilers where work). I have the following questions:
1. Can I build serial and parallel libraries at the same time, do I need
to do separate builds for each?
Yes, you can build serial and parallel at the same time. However, I typically
build serial and parallel installs separately. Why? Because I typically build
only static libraries and I don’t want serial clients to have to link with MPI
library in order to use HDF5. So, I generate a libhdf5.a that *does*not* depend
on MPI and another libhdf5.a that *does* depend on MPI using separate
configures and separate —prefix. If using shared libs, you *might* be able to
finesse this a bit and get by with just one shared lib with MPI references, I
don’t know.
2. When I have tried building using a configuration like this:
./configure \
--prefix=/usr/pppl/gcc/5.4-pkgs/openmpi-1.10.3-pkgs/hdf5-1.10.0-patch1 \
--enable-build-mode=production \
--enable-unsupported \
--enable-fortran \
--enable-cxx \
--enable-hl \
--enable-shared \
--enable-static \
--enable-parallel \
--with-zlib \
--with-szlib=/usr/pppl/gcc/5.4-pkgs/szip-2.1 \
CC=mpicc \
CXX=mpicxx \
FC=mpif90 \
2>&1 | tee configure.log
the 'make check' command just hang when it gets to testphdf5.
Well, you may need to set RUNPARALLEL enviornment variable to something
appropriate for your MPI installation
On my OS X system, RUNPARALLEL defaults to “mpiexec -n ${NPROCS:=6}” and that
works.
And, if your system doesn’t support interactive parallel runs, then you may
need to setup an srun or msub script to support it.
try “make RUNPARALLEL=foo chec” and see if that fails looking for command
“foo”. It it does, then just gin up the correct magic for value of RUNPARALLEL
to make it run a parallel executable.
HTH
Mark
After a
couple of minutes 'top' shows that there is nothing going (no noticeable
CPU or RAM usage, like what ever program was running completed or
crashed, but the make process, or script launched by make doesn't
realize that. Has anyone else seen this? Any ideas what's causing this?
