Performance Study of the First Three Intel Multicore Processors

Ami Marowka

Abstract


The transition from sequential computing to parallel computing represents the next turning point in the way software engineers
design and write software.
This paradigm shift leads the integration of parallel programming standards for high-end
shared-memory machine architectures into desktop programming environments. In this
paper we present a performance study of these new systems. We evaluate the
performance of an OpenMP shared-memory programming model that is integrated into
Microsoft Visual Studio C++ 2005 and Intel C++ compilers on a multicore processor.
We benchmarked using the NAS OpenMP high-level applications benchmarks and the
EPCC OpenMP low-level benchmarks. We report the basic timings and
runtime profiles of each benchmark and analyze the running results.
