The following is the way to figureout what petsc configure will download/install

balay@troll /home/balay/petsc (master=)
$ ./configure --with-packages-download-dir=$HOME/tmp --download-hypre

Configuring PETSc to compile on your system
===============================================================================
Download the following packages to /home/balay/tmp
hypre ['git://https://github.com/LLNL/hypre',
'https://github.com/LLNL/hypre/archive/v2.14.0.tar.gz']
Then run the script again
balay@troll /home/balay/petsc (master=)

For one - I see the following code in hypre.py

if self.openmp.found:
args.append('--with-openmp')

Normally - I use PETSc configure to install pacakges - and reuse them later -
in the following way:
<install hypre in $HOME/soft/hypre>
./configure --download-hypre=1 --prefix=$HOME/soft/hypre
<now use preinstall hype from PETSc>
./configure --with-hypre-dir=$HOME/soft/hypre
make
In this case you can try:
./configure --download-hypre=1 --prefix=$HOME/soft/hypre --with-openmp=1
PETSC_ARCH=arch-hypreinstall
./configure --with-hypre-dir=$HOME/soft/hypre PETSC_ARCH=my-regular-build-arch
[and no openmp option]
make PETSC_ARCH=my-regular-build-arch
One caveat: sometimes - mixing openmp compiled code with non-openmp
build of PETSc can give link errors [as compilers/linkers do different
stuff internally during linktime] - so this might not always work.
