====== PDE1 ======
The PDE1 benchmark approximates solutions to 3-dimensional discrete Poisson equations by means of red/black successive over-relaxation. It has previously been studied in compiler performance comparisons in the context of HPF, and reference implementations are available with HPF compilers. [[cases:pde1:implementation|Implementation]] sketches out the PDE1 benchmark and its HPF implementation, before some alternative SAC implementations are discussed. Their runtime performance is compared to that of the HPF code in [[cases:pde1:evaluation|Evaluation]].
