Title:		EXPLORING THE CELL WITH HPEC CHALLENGE BENCHMARKS

ABSTRACT:

New architectures require thoughtful testing to explore the performance 
potential of the processor.  Here the HPEC Challenge Benchmarks are used to 
explore the Cell processor to understand the realistic performance as well as 
how that performance can be attained.  More specifically, for the time domain 
FIR benchmark, we find that a significant fraction (88%) of the peak 
performance can be achieved (as expected).  However, this performance does come 
at significant coding cost.
