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-io-stringy
This toolkit primarily provides modules for performing both traditional
and object-oriented i/o) on things other than normal filehandles; in
particular, IO::Scalar, IO::ScalarArray, and IO::Lines. In the more-
traditional IO::Handle front, we have IO::AtomicFile which may be used
to painlessly create files which are updated atomically. And in the
"this-may-prove-useful" corner, we have IO::Wrap, whose exported
wraphandle() function will clothe anything that's not a blessed object
in an IO::Handle-like wrapper... so you can just use OO syntax and stop
worrying about whether your function's caller handed you a string, a
globref, or a FileHandle.
