Detailed Description

template<typename ExecSpaceType = void>
class Intrepid2::RealSpaceTools< ExecSpaceType >

Implementation of basic linear algebra functionality in Euclidean space.

Note:

Compiled on devices (KOKKOS_INLINE_FUNCTION)
Callable on devices and Kokkos functor (no temporary allocation)
parallel_for inside of Intrepid functions is dictated by the provided execution space
With Kokkos::Serial, functions (that already contain parallel_for) can be nested in Kokkos functors
When a function is decorated with KOKKOS_INLINE_FUNCTION, remove Teuchos testing and std::vectors
For norm and det computations, the value_type is chosen from the first input container.
As the name says, the class assumes that input containers are "real type" and not complex type.
Functions that are designed for small problems are not parallelized e.g., dot, norm and det. These functions have non-void return types and expect to be used for small problems. However, high level (working on cell-level) functions are parallelized.
