Detailed Description

Dummy parallel descriptor used for sequential computations.

Its only useful information is the total number of items hold by the array which can be big (hence the use of trustIdType).

In this class, all the inherited counters accessors (get_nb_items*() methods, etc.) return this number. We however carefully check that the number of items fit within 32b since thoses inherited accessors return 'int'. No piece of code is actually using those methods in the 64b part of the execution (i.e. before Scatter).

Historically we used a MD_Vector_std for sequential computations too, and this std MD_Vector had a single block covering the whole array. But having a template version of the MD_Vector_std class (supporting both 32b and 64b) seemed unreasonable, hence the creation of the current class.

See arch.h.in for more explanations on 64b.

In this class, members inherited from MD_Vector_mono are meaningless and their information is not updated. Algorithm like get_sequential_items_flags() are actually overriden not to use this.
