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.

lmod
Lmod is a Lua based module system that easily handles the MODULEPATH
Hierarchical problem. Environment Modules provide a convenient way to
dynamically change the users' environment through modulefiles. This
includes easily adding or removing directories to the PATH environment
variable. Modulefiles for Library packages provide environment variables
that specify where the library and header files can be found.
