Perhaps not as much as from a comparison or size-by-side formulation of SPMD programs using the **coarray** Fortran approach relative to the MPI model but as a semiformal reference into the thoughts of an inventor of the coarray model, a resource worth reviewing closely is [**Parallel Programming with Co-arrays**](https://www.taylorfrancis.com/books/mono/10.1201/9780429437182/parallel-programming-co-arrays-robert-numrich) by Robert Numrich (Taylor & Francis, 2018).
