Why is HydraCAT?

HydraCAT is necessary for several reasons:

Proof of Concept - In order for Chip Multiprocessors to be accepted, it needs to be shown that they can be an easy compile target.
Efficiency - The translation process is time-consuming and error prone when done by hand. Having an automatic translator gives speed and accuracy to the process.
Research Vehicle - From my point of view, the HydraCAT architecture is an excellent research vehicle for experimentation on all manners of source translation and feedback-based optimization of parallel programs.
