Detailed Description

Class allowing access to the shared memory part between sub-domains of the same node of a 2D array variable.

It is necessary that this variable be allocated in shared memory with the property "IVariable::PInShMem".

In this class, only the first dimension can be different for each sub-domain. The second dimension must be the same for all sub-domains.
