Spack will be used to manage open source software packages on Fugaku.
Fugaku users can easily use pre-installed packages and built packages based on Spack recipes.
The following list shows the results of building/compiling packages for aarch64 according to the Spack recipes.
Note that the results in this list do not guarantee that each package will work properly.
On the other hand, Fujitsu will provide the following packages compiled with Fujitsu compiler on Fugaku as "external" packages, of which Spack can be aware.

perl-file-chdir
Perl's chdir() has the unfortunate problem of being very, very, very
global. If any part of your program calls chdir() or if any library you
use calls chdir(), it changes the current working directory for the
*whole* program. This sucks. File::chdir gives you an alternative, $CWD
and @CWD. These two variables combine all the power of chdir(),
File::Spec and Cwd.
