Detailed Description

Comprehensive doctest-based unit tests for DNDS::ArrayTransformer ghost/halo communication, run under mpirun with 1, 2, and 4 ranks.

Tests pull-based and push-based ghost exchange for TABLE_StaticFixed, TABLE_Fixed, CSR, and compound element types. Also covers persistent communication and BorrowGGIndexing.

See also: DNDS Core Unit Tests for the full test-suite overview.

Test:: ParArray basics, pull (StaticFixed, Fixed, CSR, std::array), persistent pull, BorrowGGIndexing, push.
