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-perl-unsafe-signals
Quoting perl581delta: In Perl 5.8.0 the so-called "safe signals" were
introduced. This means that Perl no longer handles signals immediately
but instead "between opcodes", when it is safe to do so. The earlier
immediate handling easily could corrupt the internal state of Perl,
resulting in mysterious crashes. It's possible since perl 5.8.1 to
globally disable this feature by using the PERL_SIGNALS environment
variables (as specified in "PERL_SIGNALS" in perlrun); but there's no
way to disable it locally, for a short period of time. That's however
something you might want to do, if, for example, your Perl program calls
a C routine that will potentially run for a long time and for which you
want to set a timeout. This module therefore allows you to define
UNSAFE_SIGNALS blocks in which signals will be handled "unsafely". Note
that, no matter how short you make the unsafe block, it will still be
unsafe. Use with caution.
