Abstract
We present a compiler for machines with an explicitly managed
memory hierarchy and suggest that a primary role of any compiler
for such architectures is to manipulate and schedule a hierarchy of
bulk operations at varying scales of the application and of the ma-
chine. We evaluate the performance of our compiler using several
benchmarks running on a Cell processor.

The advances in semiconductor technology that have dramatically
increased the performance possible on a single chip have also un-
