Spack will be used to manage open source software packages on Fugaku.
Fugaku users can easily use preinstalled 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.

The Software for Linear Algebra Targeting Exascale (SLATE) project is to
provide fundamental dense linear algebra capabilities to the US
Department of Energy and to the highperformance computing (HPC)
community at large. To this end, SLATE will provide basic dense matrix
operations (e.g., matrix multiplication, rankk update, triangular
solve), linear systems solvers, least square solvers, singular value and
eigenvalue solvers.
