Detailed Description

Comprehensive doctest-based unit tests for DNDS::ArrayDof (degree-of-freedom array) vector-space operations.

Run under mpirun with 1, 2, and 4 ranks. All MPI-global reductions (norm2, dot, min, max, sum, componentWiseNorm1) are tested with rank-aware expected values that scale correctly at any process count.

See also

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

Test:

setConstant, operator+= (scalar/array/matrix), operator-=, operator*= (scalar/element-wise/matrix), operator/=, addTo, norm2, dot, min, max, sum, componentWiseNorm1, operator= (copy), clone, scalar-array multiply, identity dot(x,x)==norm2(x)^2.
