  We present a first look at ProtoX, a code generation framework for stencil
and pointwise operations that occur frequently in the numerical solution of
partial differential equations. ProtoX has Proto as its library frontend and
SPIRAL as the backend. Proto is a C++ based domain specific library which
optimizes the algorithms used to compute the numerical solution of partial
differential equations. Meanwhile, SPIRAL is a code generation system that
focuses on generating highly optimized target code. Although the current design
layout of Proto and its high level of abstractions provide a user friendly set
up, there is still a room for improving it's performance by applying various
techniques either at a compiler level or at an algorithmic level. Hence, in
this paper we propose adding SPIRAL as the library backend for Proto enabling
abstraction fusion, which is usually difficult to perform by any compiler. We
demonstrate the construction of ProtoX by considering the 2D Poisson equation
as a model problem from Proto. We provide the final generated code for CPU,
Multi-core CPU, and GPU as well as some performance numbers for CPU.
