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.

r-jsonlite
A Simple and Robust JSON Parser and Generator for R. A fast JSON parser
and generator optimized for statistical data and the web. Started out as
a fork of 'RJSONIO', but has been completely rewritten in recent
versions. The package offers flexible, robust, high performance tools
for working with JSON in R and is particularly powerful for building
pipelines and interacting with a web API. The implementation is based on
the mapping described in the vignette (Ooms, 2014). In addition to
converting JSON data from/to R objects, 'jsonlite' contains functions to
stream, validate, and prettify JSON data. The unit tests included with
the package verify that all edge cases are encoded and decoded
consistently for use with dynamic data in systems and applications.
