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.

yaksa
Yaksa is a high-performance datatype engine for expressing, managing and
manipulating data present in noncontiguous memory regions. It provides
portable abstractions for structured noncontiguous data layouts that are
much more comprehensive compared with traditional I/O vectors. Yaksa
imitates parts of the MPI Datatype system, but adds additional
functionality that would allow it to be used independent of MPI. It
provides routines for packing/unpacking, creating I/O vectors (array of
contiguous segments) and flattening/unflattening datatypes into process-
portable formats. Yaksa's backend includes support for CPUs as well as
different GPUs.
