d4.01.02 Some underground data structures

Summary:

Some « underground » data structures are described here. These are the ones that can be accessed in the code without passing as an argument because their name is known a prima facie. This is only possible because these SDs are « unique » (a kind of global variable).

Note:

To better understand the concepts mentioned in the SD*subterranes related to parallelism and linear solvers, you can consult the documents:*

*D4.01.03 (*Distributed data structure and parallelism), *

*U2.08.06 (*Parallelism user manual), *
