vec_fma Subroutine

public subroutine vec_fma(fieldProp, inState, outState, auxField, neigh, nElems, nSolve, level, layout, params, varSys, derVarPos)

Testing routine which performs fused multiplication and addtion on the state variable. The calculation is simple, so that the cost is mostly due to the data transfer through the memory interface.

This subroutine interface must match the abstract interface definition kernel in scheme/mus_scheme_type_module.f90 in order to be callable via compute function pointer.
